I have come across an interesting issue with Altirra and keyboard input. I mentioned this in passing within the Altirra release discussion, but thought it was worth a thread to itself.
MyBIOS requires you to press Start+Select+Option simultaneously in order to enter its setup menu. These Atari keys are emulated by Altirra with F2, F3 and F4 respectively. So far so good. However it seems that my keyboard - and from what I have read most PC keyboards - will not register three key-presses at the same time. Judging from the appropriate section of the Atari "Self Test"; any combination of two from Start, Select or Option DOES register, but not all three. It is impossible therefore to enter the MyBIOS setup menu!
Again. this seems to be a Windows/Hardware problem and not a shortcoming within Altirra. I was wondering if Avery or anyone else could suggest a solution?
