[ukvac] Mame Keyboard Interface
Would there be any interest if I produced a joystick-keyboard interface
for use in Mame?
I, like many others I presume, play games on Mame using the circuit
board from a PC keyboard that has joysticks and switches connected
where the key contacts would normally be. Most of you will be aware
that this is not an ideal situation as most PC keyboards are scanned as
a matrix and three keys pressed simultaneously can produce spurious key
presses - especially where two players are playing at the same time.
I propose to use a simple MPU like a PIC with separately wired inputs
(probably about 30 of them) which can be simply wired to a standard
control panel.
I haven't really looked at cost but in the £30 range sounds about right
to me.
Whadyya all think?
Peter
