You can probably get something good enough for pokemon by just exposing the system clock or something, but for a properly accurate RTC implementation you'd probably need to actually simulate how it works, which is that, it's not a clock, it's a timer. and Pokemon Yellow)ДЇor the RTC, aењ†'s rtc3test rom is useful for that:

Gameboy Color games start working (started with Super Mario Bros.

Ironing out sprite priority and palette issues.

First Gameboy Color game, Tetris World DX.

Blargg's instr_timing test ROM issues fixed, then all pass.

(had to look at existing implementations)

Ironed out issues with CPU instructions (second pass).

The code is a bit of a mess and I took quite a few shortcuts, but any comments and/or advice would be appreciated! I've included Windows, macOS, and Linux builds for those who want to try it out for some reason :) Once that's finished, I'd like to add save state support, and then take a stab at sound (yep, I hear it's challenging!). The main hurdle to get that running is RTC support, so I'm hoping I can get that done soon. This subreddit has been a huge help, especially for ideas on how start testing the basic functionality! My remaining goal is to get my emulator to run my favorite childhood game, Pokemon Gold. What I can say is that I have never enjoyed a project this much: I ended up spending almost every waking moment thinking about the next thing to do or bug to fix! It's been a pretty wild ride, but I think I've gotten to a point where basic emulation is working quite well.

This is my first emulator, so I didn't know what to expect. I've been in love with Rust for a while now, so I decided to use it instead of C this time around. The idea returned this Christmas: for some reason, I suddenly had the itch to start writing a GBC emulator from scratch! Judging by the posts I've seen over the past few weeks, it seems like I'm not the only who got the itch haha. I spent some time digging into available documentation, but gave up the effort fairly quickly. In 2014, I decided to start writing a Gameboy emulator in C.
