@Firehawke: oh, I said 3x3. Um, yeah, 3x2 - but yeah I don't do any console stuff.
@Hannes: the current I-PAC has 40 inputs. Ple-nty for all you're needing:
- 2 joysticks = 8
- 3x2 x2 player buttons = 12
- dedicated 4-way = 4
- admin buttons: P1 coin & start, P2 coin & start, pause = 5
Total = 29 (if you wanted dedicated 'start' and 'exit' buttons, as well as more player buttons, you're covered.)
Also note there's only one ground, because the grounds between controls are 'chained'.
Consider it high comedy....sincere tragedy....whatever...don't take it personally.
