That's right. I've started working on LittleBoy, the GameBoy/GB Colour emulator to go along with FatMan. FatMan is hardly a dead project, I just got bored working on the same thing for so long.
The screenshots above are from memory dumps, not cartridge ROMS. I'm still working on the Z80(actually Sharp80) core and I can't even start to try stuff out before it's done. As you can see the tile render function works, but the palettes are exactly right(kirbies should be lighter). The tool dialogs have FatMan have been imported and operate in almost the same way except the addresses have changed.
