C128 - RESET: Keep booting into C64 mode #99

Closed bicurico closed 4 years ago

bicurico commented 4 years ago

Hi,

I configured C= + F1 as SOFT RESET and C= + F3 as HARD RESET.

I made sure that no C64 cartridge is inserted in C128 mode.

When doing a reset, the C128 reboots into C64 mode. I think it is because to RESET I have to press the C= key, which is the shortcut to boot into C64 mode...

BUT: C= is mapped to my CTRL key, so I don't seem to have any other way to have a key shortcut to reset the C128?

Thanks, Vitor

Yes, the C= key will be down while the computer resets forcing it to C64 mode. Can you use Tab+F1 or Tab+F3 instead? That's the commodore cntrl key and is another option in the keyboard menu. Although some keyboards may not like some Tab + F# combos.

I can look into releasing the commodore key if the action is reset though.

My bad. I assumed BMC64 was referring to the hardware keyboard CTRL key and not the CBM emulated keyboard.

Of course I can and will try it and report back.

Thanks, Vitor

Hello randyrossi,

i confirm that the issue was caused by myself. After configuring SOFT RESET and HARD RESET to CTRL+F1 and CTRL+F3 it works as expected.

My mistake was to think of C= as the mapped CTRL key on my USB keyboard and then assuming CTRL gain to be the same key, when of course BMC64 is considering the mapped Commodore keys, meaning that CTRL is actually mapped to the TAB key.

By the way, I received key stickers with C64 layout. After glueing them on the keyboard, using BMC64 on a 1701 monitor works just perfect!

Thank you very much.

Regards, Vitor
