To be fair, assembly lines of code are fairly short.

Back in the day we wrote everything in asm
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.
Pssh, if you haven’t coded on punch cards, you aren’t a real coder
I don’t know if everyone gets the reference: RollerCoaster Tycoon is in fact writing mostly in assembly to use the hardware more efficiently
It also makes it really portable which is a big part of why all the ports to modern systems are so close to the original. Obligatory OpenRCT2 shoutout.
Step 1: Begin writing in Assembly
Step 2: Write C
Step 3: Use C to write C#
Step 4: Implement Unity
Step 5: Write your game
Step 6: ???
Step 7: Profit
Eww Unity
Step 6 extort developers
I mean, I’m pretty sure it would be a good learning experience so I would really not regret it.
I tried decades ago. Grew up learning BASIC and then C, how hard could it be? For a 12 year old with no formal teacher and only books to go off of, it turns out, very. I’ve learned a lot of coding languages on my own since, but I still can’t make heads or tales of assembly.
Assembly requires a knowledge of the cpu architecture pipeline and memory storage addressing. Those concepts are generally abstracted away in modern languages
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.
Try 6502 assembly. https://skilldrick.github.io/easy6502/
My favorite assembly language by far.
this page is great. starting right at “draw some pixels” in such a simple way just instantly makes it feel a bit more approachable!
If you can’t get enough 6502 you can build your own http://wilsonminesco.com/6502primer/
I built a 6502 SBC on a breadboard years ago
cool! I’d stick with commodore 64 if I ever actually do anything tho (very unlikely)
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.
Shifts bit to the left
Um what am I doing
Shifts bit to the right
program crashes
This game ran so smooth.
Reminder that ttd was open source even before open ttd :D
I want to get off Mr. Bones’ Wild Ride
Roller coaster Tycoon is one of a lifetime game.
Now everything is electron or react shit. Gone are the times of downloading fully featured software under 10mb.
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.
Further proof C++ is a pita
int main()
{
std::cout << "C++ is simple and fun ... you cretin\n";
return 0;
}I had a machine language course in uni, parallel with a C++ course. Not a fun semester to be my wife, or a relative of any of my classmates. Best case our brains were in C++ mode, worst case you needed an assembler to understand us.
And yes I know my code format will piss people off, I don’t care, it’s the way I write when other less informed people don’t force me to conform to their BS “Teh oPeNiNg bracket shouwd bwee on teh sam line ass teh declawation”
Edit: added a \n for the sake of pedantry :)
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.
But the game is “finished”. there is no need for alterations.
If only that was the case. But there is no chance a game built for windows 95 could run unaltered on an android phone. Things like the rendering systems, input handling, and sound output will need to be adapted to work on a new platform.
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.
Thank you. That is a good example.
But the modern OpenRCT, written in an actual language, is better in every way.
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
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.
I listen to music on a new music radio station - the good new music really stands out
Most people just like the (better bits of) stuff they listened to when they were young
That isn’t the whole picture. I was born in 1988. The sampling of music from the 70’s that I’ve been exposed to is completely different to the sampling of music from the same period that someone born in '58 was exposed to in their lifetime. They got to listen to a bunch of bad stuff (and probably some great stuff) that I don’t even know exists.
Chris Sawyer is a madman.
I believe you meant to write genius.
They call me the Programmer and I speak to the metal,
Now check out this app, that really shows off my mettle!
I don’t know exactly how much code reuse Sawyer had going back then, but if you’ve ever played Transport Tycoon (or more likely the open source version around today, OpenTTD) then you know that the interface and graphics are extremely similar. So it’s not like he started from scratch each game with nothing but a hot spinning disc and a magnetized needle.
But yeah, the main reason to put up with all the modern framework bloat is the ever-ephemeral promise of being able to write your thing once and have it ported to run anywhere with minimal to no further effort.
I love Roller Coaster Tycoon. It’s absolutely crazy how he managed to write a game in a way many wouldn’t even attempt even in those days, but it’s not just a technical feat, it’s a creative masterpiece that’s still an absolute blast to play.
It still blows my mind how smoothly it gives the illusion of 3D and physics, yet it can run on almost anything.
OpenRCT brings a lot of quality of life and is often the recommended way to play today, but the original RCT will always deserve a spot on any “Best Games of All Time” list.
It was even ported to the original Xbox. I remember the total games file size being incredibly small - compared to most other titles on that system.
If you’ve written 500k lines of code you were surely pretty confident about your decision.
You sweet summer child…
I’m a developer, I don’t just continue doing things for years if it doesn’t make sense.
(If I’m the one making the decisions)
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.
Shhhh you just described iterative development. Careful not to be pro agile, or the developers with no social skills will start attacking you for being a scrum master in disguise!
Fuck agile, or scrum, or whatever it is called. I just look at the issues and pick whatever I feel like doing. Kanban for life.
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.
