Digging up this thread again. Been a lot more progress recently on my GB emulator. Turns out the trouble I had (garbage background data) that I spent weeks working on was really just a simple error (wrong opcode in the CPU). As I suspected, taking some time away from the issue and the problem became immediately clear once I started working on it again :p
Finally got background palettes to work and it can boot up from the GB BIOS instead of using HLE. Next up, sprites.

The CPU cheats, so it always wins or gets a cat game
