gbapfomgd VS cc65

The same way you learn everything, look at examples, read the docs, and keep trying. I had to write assembly while I was still in school for Comp Sci, in 2017 so people still learn ASM in modern times lol. We did it for the mips architecture. But I wrote a gameboy game a few years ago with ASM, and that would probably be a more fun first assembly project. Here you go: https://github.com/ahrnbom/gbapfomgd

Feel free to check out my book if you want an easy starting point. https://github.com/ahrnbom/gbapfomgd

True. The code generated by https://cc65.github.io/ is pretty decent but there are a few places where hand-rolled assembler will perform much better when you need it. Although I've made things for 6502-based systems in C with this handy compiler (thanks cc65 contributors!).

Is there something intrinsic to how C handles addressing that makes segmented architectures more painful than they ought to be? Or maybe is there a language where segmented addressing is easier?

I hadn't really thought about it in a while. :)

cc65

There's tools like cc65 that let you write C code for the NES.

You can use any text editor for coding and the tutorial uses cc65 for compiling assembly to machine code.

You can use cc65 https://cc65.github.io/ but because you are compiling it in a limit hardware the cc65 has its rules and recommendations to follow in order to get the most optimal binaries, and more specifically I read this when I made the "Pong" game for NES as a practice long time ago https://nesdoug.com/ , I hope it helps, happy coding!

What assembler/tools did you use anyways? Personally I'd recommend ca65 from the cc65 C compiler utility. It's very powerful, open source, and kept updated (unlike a lot of ancient 6502 tools, like WDC's)

It really is a cool project. https://github.com/cc65/cc65

It provides some template configuration files describing different memory layouts. And provides common libraries for input/output.

There's also a LLVM fork for MOS: https://github.com/llvm-mos/llvm-mos

They've got some interesting hacks with ZeroPage memory and register allocation: https://llvm-mos.org/wiki/Code_generation_overview

Interesting if you geek out on that kind of research.
