    • Project mention: Best compiler to write .nes cartridge ROMs for testing my own emulator? | /r/EmuDev | 2023-12-06

    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.
