Game supporting multiple buttons

[Mrs Beanbag]

I still need to get round to making that Megadrive pad adapter... in theory it should be possible to program to use all the buttons if only two wires are swapped round. Not that that will help with existing games, but I hope to be able to take advantage of it in future.

The ADoom manual recommends swapping pins 5 & 7 and putting a 470 ohm resistor between them. Hired Guns and ADoom support 3 buttons then. I recall some emulators did also. None of the buttons map to other CD32 buttons so different code has to be used to read a 3 or 6 button Sega controller than a CD32 controller.

I read elsewhere it's recommended to use diodes as well because the Sega pad pulls lines up to +5V whereas the Amiga only expects connections to ground.

The code is much simpler than reading a CD32 pad, the extra buttons are simply multiplexed. Unlike the CD32 which uses some kind of serial protocol.

How's Mr Beanbag doing? Has there been any recent updates?

I've made it so you can load in special levels from the main menu, and fixed a couple of bugs, but not uploaded anything lately, really should upload something soon.
