      Fun quote from an interview with Chris Sawyer:

      Latterly the machine code came back to haunt us when the decision was made to re-launch the original game on mobile platforms as RollerCoaster Tycoon Classic a few years ago, and it took several years and a small team of programmers to re-write the entire game in C++. It actually took a lot longer to re-write the game in C++ than it took me to write the original machine code version 20 years earlier.

          It’s probably not because it’s sucks. It’s because they’re trying to perfectly replicate an existing target. They have to read the assembly, digest it, then create the identical solution in C++. If they were just creating a new game, it likely would be much faster.

        Is there not a way to take assembly and automatically translate it to some higher level language?

        Edit: Post-post thought: I guess that would basically be one step removed from decompilation which, as I understand it, is a tedious and still fairly manual process.

          Your thought is correct. The basic problem is that higher level languages contain a lot of additional information that is lost in the compilation process.

            But do we need this information then? E.g. shouldn’t it be possible to just write what the assembler is doing as a c++ code?

            E.g. high level languages also support stuff like bitwise operators and so on.

              You could, but there isn’t much benefit. The purpose of all that extra information is generally to make the program easier to understand for a human. The computer doesn’t need any of it, that’s why it’s not preserved in compilation. So it is possible to automatically translate assembly to C++, but the resulting program would not be much (if any) easier for a human to understand and work with.

              To give a bad analogy, imagine some driving directions: turn left at 9th street, enter the highway at ramp 36, go right when you’re past the burger king, etc. These are translated into physical control inputs by the driver to actually take the car to its destination. Now we could look at the driver’s physical inputs and turn that back into a written list of instructions: turn the wheel left 70 degrees, turn it right 70 degrees, push the gas for 10 seconds, and so on.

              All the street name references are now gone. There are no abstracted instructions like “enter the highway” or even “take the second left.” It would be quite difficult for a person to look at these instructions and figure out the trip’s destination. Let alone make some alterations to it because there is roadwork along the way and a detour is needed.

                I get that. But the game is “finished”. there is no need for alterations. translating the assembler code into c++ in this way could serve to quickly get it in a format that is then compileable for other platforms.

              Take for example Haskell. It’s a functionnal, typed language. In Haskell, at compile time, the compiler analyzes all the types of all your functions and if they all match, it drops them completely. There is no type information at all left in a compiled Haskell program, because the compiler can know ahead of runtime if it is correct.

      I don’t think old=good is a good mentality though, lot of people seem to have it

      All the old software I know and use is exceptionally good, however I’ve heard about and chosen to use it because it’s survived the test of time (also because it’s still actively maintained and has had thousands of bug fixes over the years)

      Vscode and obsidian are pretty good and they’re electron, discord’s alright, pretty sure steam uses some kind of web wrapper as well.

      Real issue is electron is very accessible to inexperienced developers and easy to do badly, but I imagine people back in the old Unix days got an equal amount of shit bloated software

          An intern was using it, but I saw that he had set it up to run locally and connect to the ETX we were using and figured he had found a way to avoid that. Nope, turns out it runs a server on the ETX that also likes to fill up the home dir and he also just uses vim now.

        Old=good is a great mentality specifically when standing the test of time is an important factor. For the most part, the old code that’s still used today is only still used because it’s proven good, whereas it’s a grab bag with newer code. And that’s the cause of the unwarranted nostalgia thay you’re rightfully criticising.

        It’s like with music. “Oh, the X’s were the best decade for music, today’s music is garbage”. No, 90% of everything is crud but unless you’re an enthusiast, once enough time has passed, you’ll only ever be exposed to the 10% that isn’t. 50 years from now nobody is going to be listening to Cardi B.

They got to listen to a bunch of bad stuff (and probably some great stuff) that I don’t even know exists.

          You are very unlikely to write assembly that is more optimized than what a modern compiler could produce for anything longer than a trivial program. I don’t know if it made sense at the time of the original RCT, but OpenRCT would definitely not benefit from being written in assembly.

            I feel like that’s only true if I was asked to “write the assembly for this c++ program.” If I’m actually implementing something big in assembly, I’m not going to do 90% of the craziness someone might be tempted to do in c++. Something that is super easy in c++ doesn’t mean it’s easy for the CPU. Writing assembly, I’m going to do what’s easy for the CPU (and efficient) because, now, I’m in the same domain.

            The bottom line is cranking up the optimization level can get you a 2-5x win. Using memory efficiently can give you a 10-100x win.

              Using memory efficiently can give you a 10-100x win.

              Yes, it can. But why is this exclusive to assembly? What are you planning to do with your memory use in assembly that is not achievable in C++ or other languages? Memory optimizations are largely about data structures and access patterns. This is available to you in C++.

              Also, if you don’t want 90% of the craziness of C++ then why not just code in C++ without 90% of the craziness? As far as I know what’s what a lot of performance-critical projects do. They operate with a feature whitelist/blacklist. Don’t tell me you have the discipline to work entirely in assembly and the knowledge to beat the compiler at the low level stuff that is not available to you in C++ but you can’t manage avoiding the costly abstractions.

              I think it speaks volumes how rarely you hear about programs being programmed in assembly. It’s always this one game and never any meaningful way to prove that it would gain performance by not being written in C++ when using a modern compiler.

                I shouldn’t have used C++ as the example. Even C would work. I agree with everything you’re saying, but the original premise. I think if you put ASM vs C, C++, rust, etc, performance would fall near 50/50.

                I’m not the best assembly guy, and I’m not advocating we all write it. But I always felt that the compiler optimization assumption was wrong or weak. Everything would be aligned nicely for my sanity, not performance =]

        Writing in ASM is not too bad provided that there’s no operating system getting in the way. If you’re on some old 8-bit microcomputer where you’re free to read directly from the input buffers and write directly to the screen framebuffer, or if you’re doing embedded where it’s all memory-mapped IO anyway, then great. Very easy, makes a lot of sense. For games, that era basically ended with DOS, and VGA-compatible cards that you could just write bits to and have them appear on screen.

        Now, you have to display things on the screen by telling the graphics driver to do it, and so a lot of your assembly is just going to be arranging all of your data according to your platform’s C calling convention and then making syscalls, plus other tedious-but-essential requirements like making sure the stack is aligned whenever you make a jump. You might as well write macros to do that since you’ll be doing it a lot, and if you’ve written macros to do it then you might as well be using C instead, since most of C’s keywords and syntax map very closely to the ASM that would be generated by macros.

        A shame - you do learn a lot by having to tell the computer exactly what you want it to do - but I couldn’t recommend it for any non-trivial task any more. Maybe a wee bit of assembly here-and-there when you’ve some very specific data alignment or timing-sensitive requirement.

          I like ASM because it can be delightfully simple, but it’s just not very productive especially in light of today’s tooling. In practice, I use it only when nothing else will do, such as for operating system task schedulers or hardware control. It’s nice to have the opportunity every once in a while to work on an embedded system with no OS but not something I get the chance to do very often.

          On one large ASM project I worked (an RTOS) it’s exactly as you described. You end up developing your own version of everything a C compiler could have done for you for free.

        Writing it in assembly would make it pretty much the opposite of portable (not accounting for emulation), since you are directly giving instructions to a specific hardware and OS.

            you’re not usually directly accessing/working on the hardware

            I mean, you are. Sure, there’s a layer of abstraction when doing tasks that require the intervention of the kernel, but you are still dealing with cpu registers and stuff like that. Merely by writing in assembly you are making your software less portable because you are writing for a specific ISA that only a certain family of processors can read, and talking with the kernel through an API or ABI that is specific to the kernel (standards like Posix mitigate the latter part somewhat, but some systems (windows) aren’t Posix compilant).

      I’ve done heaps with memory managed languages in the past but shit as soon as I had to think about what I was doing under the hood everything got hard af.

      So serious question - does anyone have any good resources for a competent programmer, but with no clue whatsoever how to manage memory in a microcontroller space and avoid fragmentation etc?

        The best book I’ve ever bought on programming, and the second best book I bought for a class in uni, was https://dl.acm.org/doi/book/10.5555/1824214 it may be worth checking out on libgen and buy if it suits your needs.

        Whenever I do low-level programming on the AVR architecture, I’ll make a memory map. As in I’ll map out where I’ll put what. It may not be suitable for more complex programs, but it does the job for me. And it has enabled teamwork in assembly in the past.

        If you want to work in a language that doesn’t offer memory management, but manually mapping memory isn’t feasible either, how about building your own memory management? Or perhaps use an RTOS? I’ve used freeRTOS before on various arm-based micros, and it does take a bit to get started, but after that it’s easy sailing.

        Sorry for the following tangent, all semi intelligent content in this comment is found above this line.
        BTW I tried CoOS once, I wouldn’t recommend it… OK it was 12 years ago, I can’t remember exactly what was wrong other than the documentation was crap, but I don’t need to remember why to hold a grudge.

      Adobe promised that Lingo was the future of ‘PC and internet gaming’

      Luckily by the time I had to learn to write that garbage I already coded in several other languages. Made it easier, but somehow more painful. I’m pretty sure that shit was designed so that executives could look at the code and pretend they understood what was going on. At least with ‘common terms’ it eliminated the need for commenting out most of the time. One line of code would take a paragraph of text lol.

    Your game will actually likely be more efficient if written in C. The gcc compiler has become ridiculously optimized and probably knows more tricks than you do.

      Especially these days. Current-gen x86 architecture has all kinds of insane optimizations and special instruction sets that the Pentium I never had (e.g. SSE). You really do need a higher-level compiler at your back to make the most of it these days. And even then, there are cases where you have to resort to inline ASM or processor-specific intrinsics to optimize to the level that Roller Coaster Tycoon is/was. (original system specs)

        I might be wrong, but doesn’t SSE require you to explicitly use it in C/C++? Laying out your data as arrays and specifically calling the SIMD operations on them?

          There’s absolutely nothing you can do in C that you can’t also do in assembly. Because assembly is just the bunch of bits that the compiler generates.

          That said, you’d have to be insane to write a game featuring SIMD instructions these days in assembly.

            I think they meant the other way around, that if you wanted to use it in C/C++, you’d have to either use assembly or some specific SSE construct otherwise the compiler wouldn’t bother.

            That probably was the case at one point, but I’d be surprised if it’s still the case. Though maybe that’s part of the reason why the Intel compiler can generate faster code. But I suspect it’s more of a case of better optimization by people who have a better understanding of how it works under the hood, and maybe better utilization of newer instruction set extensions.

            SSE has been around for a long time and is present in most (all?) x86 chips these days and I’d be very surprised if gcc and other popular compilers don’t use it effectively today. Some of the other extensions might be different though.

              If you want to use instructions from an extension (for example SIMD), you either: provide 2 versions of the function, or just won’t run in some CPUs. It would be weird for someone that doesn’t know about that to compile it for x86 and then have it not run on another x86 machine. I don’t think compilers use those instructions if you don’t tell them too.

              Anyway, the SIMD the compilers will do is nowhere near the amount that it’s possible. If you manually use SIMD intrinsics/inline SIMD assembly, chances are that it will be faster than what the compiler would do. Especially because you are reducing the % of CPUs your program can run on.

              Oh I see your point. Yeah, I think they meant that. And yes, there was a time you’d have to do trickery in C to force the use of SSE or whatever extensions you wanted to use.

            Technically assembly is a human-readable, paper-thin abstraction of the machine code. It really only implements one additional feature over raw machine code and that’s labels, which prevents you from having to rewrite jump and goto instructions EVERY TIME you refactor upstream code to have a different number of instructions.

            So not strictly the bunch of bits. But very close to it.

    It still blows my mind how smoothly it gives the illusion of 3D and physics, yet it can run on almost anything.

          Like the classic, inherit a broken code base, and not being allowed by the owner to rewrite it from scratch. So you have to spend more time making each part work without the others working. Also before you are finished the customer says they have something else for you to do

            That’s when you start introducing modules that have the least impact on the legacy code base. Messaging is a good place to start, but building a new code next to the existing one and slowly refactoring whenever you got time to spare is at least a bearable way to go about it.

            Programmers love to rewrite things, but it’s often not a good idea, let alone good for a business. Old code can be ugly because it is covered with horrible leasons and compromises. A rewrite can be the right thing, but it’s not to be taken lightly. It needs to be budgeted for, signed off on and carefully planned. The old system needs to stable enough to continue until the new system can replace it.

              Okay, I’ll tell you, in this situation, the code never really worked outside of the demo stage. It was written in bash+ansibel+terraform+puppet designed to use ssh from a docker container and run stages of the code on different servers. And some of it supposedly worked on his computer, but when it failed to run when he was not clicking the buttons, and I read through each part, I can promise you that it never worked

              I didn’t write broken code base because I didn’t like the code, I meant that it didn’t work

                The whole point of docker is to solve the “work on my computer” by providing the developer hacked up OS with the app. (Rather than fixing it and dealing dependencies like a grown up)

                Bit special for it to still be broken. If it flat out doesn’t work, at all, then it may well be “sunk cost fallacy” to keep working on it. There is no universal answer, but there is a developer tendency to rewrite.

                  I’ll consede that his point in using docker was to avoid the “it works on my computer” problem. It was literally one of his talking points in his handover meeting. But that is not the problem docker is trying to solve, and not it’s strength.

                  Docker and similar container software makes many things very convenient, and has uses far outside it’s originally intended usage.

                  And in this situation, when want stable package versions, and simpler uniform setup. And you don’t have stable package versions because docker doesn’t provide reproducible builds (and he didn’t do the work work srojdn that), and it is not a simpler setup when you want to use the hosts ssh agent with ssh inside docker, which require different steps for different distros, Mac and Idk if windows would have worked? And sharing your ssh agent into the docker image is not stable either even if you set it up, it isn’t sure to work the next reboot. And can be every difficult in some Linux distros due to permissions, etc.

                  Then I ended up putting it on a vm, that is already used for utilities. If I were to do it today, I would probsbly use nix, to actually run these programs that is very sensitive to program version changes in a stable reproducible environment that can run on any Linux distro, including in docker

                  But the program had many more issues, like editing yaml files by catting them and piping them into tac and piping into sed and then into tac again… And before you say you could do that just with one sed command, sure, but the sane solution is to use yq. Let’s just say that was the tip of the iceberg

                  Oh and just have to note, claimed working features, but no way for that code the be executed, and when I actually tried to hook up this code, I can’t believe its ever fully worked.

          You don’t need to know the details of the CPU architecture and pipeline, just the instruction set.

          Memory addressing is barely abstracted in C, and indexing in some form of list is common in most programming languages, so I don’t think that’s too hard to learn.

          You might need to learn the details of the OS. That would get more complicated.

            I said modern programming languages. I do not consider C a modern language. The point still stands about abstraction in modern languages. You don’t need to understand memory allocation to code in modern languages, but the understanding will greatly benefit you.

            I still contend that knowledge of the cpu pipeline is important or else your code will wind up with a bunch of code that is constantly resulting in CPU interrupts. I guess you could say you can code in assembly without knowledge of the cpu architecture, but you won’t be making any code that runs better the output code from other languages.

I was in the first class at my school that learned Java in college. It was the brand new version 1.0.6! It was so rough and new, but honestly I liked it. It’s wildly different now.

      The game Roller Coaster Tycoon was famously hand written in raw CPU instructions (called assembly language). It’s only one step removed from writing literal ones and zeros. Normally computers are programmed using a human-friendly language which is then “compiled” into CPU instructions so that the humans don’t have to deal with the tedium and complication of writing CPU instructions.

        To further emphasize this, I had an assembly course in university. During my first lab, the instructor told us to add a comment explaining what every line of assembly code did, because if we didn’t, we would forget what we wrote.

        I listened to his advice, but one day I was in a rush, so I didn’t leave comments. I swear, I looked away from the computer for like 2 minutes, looked back, and had no idea what I wrote. I basically had to redo my work.

        It is not that much better than reading 1s and 0s. In fact in that course, we spent a lot of time converting 1s and 0s (by hand) to assembly and back. Got pretty good at it, would never even think of writing a game. I would literally rather create my own compiler and programming language than write a game in assembly.

That course was the most difficult and most fun I’ve ever had. I learned how to properly use registers to store my values for calculations, I learned how to use subroutines.

          To send the point home even more, this is how in python you make a line of text display:

          print("Hello World")

          This is the same thing, in assembly (According to a blog I found. I can’t read this. I am not build better.)

            org  0x100        ; .com files always start 256 bytes into the segment
          
              ; int 21h is going to want...
          
              mov  dx, msg      ; the address of or message in dx
              mov  ah, 9        ; ah=9 - "print string" sub-function
              int  0x21         ; call dos services
          
              mov  ah, 0x4c     ; "terminate program" sub-function

              msg  db 'Hello, World!', 0x0d, 0x0a, '$'   ; $-terminated message

            That assembly is for a DOS application. It would be more verbose for a modern Linux or Win32 application and probably require a linker script.

            But python turns that cute little line up top, into that mess at the bottom.

            Technically, not quite. Python is interpreted, so it’s more like “call the print function with this string parameter” gets fed into another program, which calls it’s own functions to make it happen.
