chip8-test-suite

These are all great projects! When I find myself getting burnt out in my job I find that writing a little toy project usually helps be get back some spark. Some projects that weren't listed that I've enjoyed: - GUI based bot for a small video game - raft consensus algorithm - ray casting - simple b-tree or lsmtree storage engine I'll also second chip8 emulator as being a good quick fun one! It helps there are ROMs that help quickly validate your implementation also (https://github.com/Timendus/chip8-test-suite)

This is my first emulator. It is still missing a few bells and whistles like the sound timer, but otherwise it passes the basic tests from Timendus (https://github.com/Timendus/chip8-test-suite). I've also been thinking about making a Fortran dialect suitable for CHIP-8 (https://fortran-lang.discourse.group/t/fortran-chip-8-interp...).

I can recommend Timendus test suite (which includes the one mentioned as well), as a more thorough set of tests and verification utilities: https://github.com/Timendus/chip8-test-suite There are a lot of other useful references and tools worth mentioning, depending on how much hand-holding you want when implementing the emulator: - http://johnearnest.github.io/Octo/ - https://laurencescotford.com/chip-8-on-the-cosmac-vip-index/ - https://tobiasvl.github.io/blog/write-a-chip-8-emulator/ Additionally, note that there are lot of variants of the instruction set / system-specific quirks, which you probably don't want to entirely ignore in an implementation. In particular, the Cowgod's reference doesn't cover this fully (Matt Mikolay's is more thorough, but doesn't cover everything either).
