Document description

OneBus or VT02/03 is a clone unit designed to play Famicom and NES games. There is a great deal of information within this package, including applications, datasheets, memory maps and register documentation about this clone unit. Extremely useful if you are hacking any games that are meant to be played on the OneBus unit. Most of the games are fully compatible with the standard NES/Famicom with the exception of the games that use 4BPP graphics and the dual APU.

It is also possible to program a game for this particular clone unit with the information therein.
