morelenmir Posted March 21, 2013 Share Posted March 21, 2013 (edited) 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? Edited March 21, 2013 by morelenmir 1 Quote Link to comment Share on other sites More sharing options...
Rybags Posted March 21, 2013 Share Posted March 21, 2013 (edited) Seems it might be dependant on the PC keyboard in use - mine is happy to return all 3 pressed in both cooked/raw keystroke mode. I don't think Input Mapping options can help. The solution unless Avery can produce some special version might be to alter the BIOS image to accept a different hotkey setup to enter the menu.

morelenmir Posted March 21, 2013 Author Share Posted March 21, 2013 I think it might be specific to PS2 keyboards from some further reading. My current, otherwise very nice and clicky Logitech goes back 11 years... So... That could well be it. Quote Link to comment Share on other sites More sharing options...
Rybags Posted March 21, 2013 Share Posted March 21, 2013 Mines a cheap MS keyboard using the PS2 port. Most PC keyboards will get ghosted/masked combinations, I don't think PS2/USB matters very much. Quote Link to comment Share on other sites More sharing options...
morelenmir Posted March 21, 2013 Author Share Posted March 21, 2013 I guess it must be the Logitech keyboard itself then... Ah well. I have sort-of-bodged a keyboard macro that almost works. Kind of...!!! Quote Link to comment Share on other sites More sharing options...
