Re: What a complete cockup this Vega thing is!
@ Lost all faith...
Actually it shouldn't be all that difficult to hack a 9 pin D port onto an existing bluetooth game controller. Throw in a microcontroller for the interfacing and you can use the extra buttons on the old 6-button Sega Megadrive joypads too.
I have a Zeemote JS1 bluetooth game controller but it's a right pain in the arse to get paired up and working properly on an Android device, perhaps there's a better working (connectivity wise) cheap bluetooth joypad out there that can be hacked.
