(shudder) Yes - that's a big problem. And by now i have no ideas how to change speed for chanel 0 of the system timer. :((( Only one idea - to program RTC for interrupts but that's not nice too. But we will need some decision in that problem - i whant to run games :) P.S. btw keyboard hadnling by now works not well to - as soon as possible i will work with that problem in new consoles support module.
