Hi,

A while ago I happened to stumble upon new Sega Megadrive joypads from Dealextreme, and a while ago, I finally got the package. Actually they are made for "Megadrive emulator inside joypad" (to use as second controller), but apparently the connector and pinout is the same as in the original controller. Which, of course, also means it works on Amiga straight away.

NOTE: If you are going to use these on Amiga (or any other non-smd system with similar connector), it's probably a good idea to remove the single muxer chip, and do some rewiring. I heard somewhere, that certain button combinations might end up putting 5V on wrong (on Amiga) pin or something... Also, it's not easy to convert these to fully functional CD32 pads, so don't ask me "how?" you should be able to get 2-3 buttons working easily though.

The controllers are quite a bit smaller than I had expected, but at $4.55 you might not be able to buy D9 connector and cable (and would have to solder it, and it would look worse) so could be useful to repair joysticks with broken cables aswell. The directional pad is higher-than-usual (you actually have to move it to direction, rather than just press), and it's not possible to press f.ex. left and right simultaneously (diagonals work, of course). Especially the 3 lower buttons feel better than I had expected. All 9 cables are connected to the circuit board, so should be convertible to 2-button MSX pad aswell (one friend of mine pointed out that the "2nd button on MSX" pin isn't always connected).

Then some pictures:

The pads look like this.
Size comparison with Tac-2 and Competition Pro.

Haven't had time to do any proper experimenting yet, does anyone have any documentation on adding autofire? Would be nice to add it to those extra buttons...

Eek... incorrect voltage. That sounds chillingly familiar.
