Not sure about that AND #60 bit.
Are you trying to trigger on any multiple of 60?
Cause that won't do it.

You're better off deriving your count value from the clock, rather than counting yourself.

I want to add d64 capability to Vic20chrome/JSVic20 and I know that VICE can either emulate a full drive or basically hack one.
What functions in the kernel does it hack into to do this?

Function keys in emulator are now mapped the same as vice.

Ok, I'll put on a list of things to fix.

Fun. Love the music

@matsondawson Thanks for putting this on your page for online play but I have noticed a problem. F1 works ok to start the game but F7 wont stop it. In fact F4 which would normally quit the game stops the timer instead. :cry: Any ideas why? Is it because: PC = CBM ----------- F1 = F1 F2 = F3 F3 = F5...

I have the exact TV in my collection except without that name on the front.
It's B&W, so prob. not best for a VIC-20

> When you want to make the 3K extra RAM accessible to the VIC chip, you must add it at the correct side of the buffers, and that is only possible on the mainboard. The plan was to have an adapter you plug on the main board that also adapts to the cart slot. i.e. you plug onto the VIC side of the bu...

Would it be possible to add an adapter to the cart port that exposes the VIA bus on via cycles for RAM1,2,3? I'm guessing you'd have to decode the RAM1,2,3 for the VIA cycles, and block any chips selects/RW coming from the CPU. Maybe about 5 ics worth? Edit: Wouldn't require any soldering then. Of c...

All the images are dead in this thread, any possibility of a refresh?

I like the challenge of programming through its limitations.

Wow, So the current solutions are all user port? I'd connect the joysticks all to the standard port, and round robbin the +5v line to them, using the fire button line to toggle each successive joystick, by grounding it temporarily. Should only require one of those led chaser chips or similar. Or may...
