Now working in compatible (single fire button) mode with the ability to add B as up for games which use up to jump.
Also has 2-3 button modes with active high (C64) and low (some C64, Amiga and Kempston). Atari 8bits could also use this, not sure if any games do though?
I did a quick new layout for the MegaMulti, which is to be a multi-platform version of the Mega7800.
It will support Amiga, CD32, Atari ST, C64 and Spectrum (Kempston). Amiga and C64 will also support light guns.
No Amstrad CPC unfortunately, as it's a bit weird.
