Tetris for the Mega Duck This Romhack brings classic Game Boy Tetris to the Mega Duck console (a clone with various changes to make it incompatible with the GB).

It’s a modified version of the dissasembly by vinheim3: https://github.com/vinheim3/tetris-gb-disasm.

Most of the work for this port was in adapting the Tetris music and sfx driver to accommodate the shuffled APU register addresses and bit values.

The patch is in UPS format.

Playing on console hardware: As with unmodified Tetris this is meant to run on a bare 32K cart with no save RAM and no MBC. For now Inside Gadgets has the only compatible flash cartridge, it can be used with OEM shells or 3D printable cart shells: https://github.com/bbbbbr/megaduck_cartridge_shell.

Playing on console emulators: If the patched ROM is played in an emulator then most likely the music and sfx will sound incorrect to some degree. At this time all Mega Duck emulators I’m aware of do not handle NR32 correctly, some may lack other required changes.
