😀 The Acid2 test, now for the original Game Boy! 😀 (by mattcurrie)
jsmoo
Multi-system, pure JavaScript (& a little AssemblyScript) emulator, with great accuracy and speed. Currently some SNES, NES, GameBoy, Master System, ZX Spectrum, and GameGear support (by raddad772)

What is the "window internal line counter?"
My Game Boy emulator has almost passed dmg-acid2, except that it has the "Eye displayed instead of right chin" failure mode. The README says that this signals an issue with the "window internal line counter," but I don't see where that's documented. Can someone enlighten me?

I've made a Game Boy emulator using Rust and WebAssembly 🎮🕹️
I tested it with the classic dmg-acid2 test rom and another rom called sprite_priority.gb which is part of the Mooneye Test Suite.

What are good systems to emulate for learning purposes?
For everything beyond opcodes, and especially graphics, the pandocs go over almost everything you need. For testing graphics, you can use the dmg-acid2 test roms which have tests for most of the common graphics errors.

DMG-01 GameBoy emulator with debugger written in C++ using Win32 and SDL2
Adequate PPU emulation (passes dmg-acid2 test). This emulator uses Pixel FIFO, as opposed to common scanline renderer.

acid-dmg, this is a really nice PPU test, you can try to complete it step by step.

Best compiler to write .nes cartridge ROMs for testing my own emulator?
If you really want to use it, I have a bad 65816 assembler at https://github.com/raddad772/jsmoo/blob/main/component/cpu/wdc65816/wdc65816_assembler.js . Just don’t switch it to 65816 mode and it should produce compatible code. I wrote it as a pile of hacks on top of each other and you still need to add an iNES header.

Trouble with GB Joypad Input
If you want to really verify your CPU, check out https://github.com/raddad772/jsmoo/tree/b3807b55f03cdad2191810b2a770781d73c41870/misc/tests/GeneratedTests/sm83 , a set of 1000 tests per opcode, cycle by cycle, including read and write bus activity, in JSON format. It’s a bit of work to integrate them but there’s no better CPU test. Also you can generate more if you want to by using the code generation portion of the codebase. The only thing it doesn’t really test well is IRQ/halt stuff. It’s pretty common for folks to pass Blargg and still have things uncovered here. Usually things Blargg can’t test, or symmetric errors (flag both set and tested wrong), or corner cases Blargg didn’t think of.
