Hi lads,after reading the forums for AGES,getting to know the scene,as im half way through my first mame machine. I think its time to start posting lol. Just a bit of input on this thread. My ps2 keyboard would turn the computer on. Now same as above,since it goes through the USB Mini-Pac it doesnt anymore. But heres a couple of thoughts. 1.If you have the USB don't the benifits overweigh the "key to power on function"? 2.If you use a trackball/spinner,then you will loose the power for them with PS2. 3.If you go USB to PS2 adapter,again you will loose the benifits? I reckon what brian said is the best,just run your PC power switch to a switch.
