If it's working, can't be much wrong with it. Check continuity right through to your diag board.

At the risk of being patronising, are you certain you have the connector on the right way around? It isn't keyed and can go on both ways, I've written top on mine

Does the cassette actually load and save a game?

@beamrider: There's some idea I cannot get rid of. As those few sprites seemed to spark some interest, perhaps many would be grateful for a web editor to bring on a complete set of sprites and charsets. But to be honest: the VIC Screen Designer's user interface is far too complicated for anyone to ...

I like the ideas in the BBC version which sounds reasonable. Also the number of monsters could be reduced, such as the platforms, if needed.. Yes, that is what you should be aiming for although the beeb runs at twice the speed of the Vic. If you went for Multicolor mode that helps as your objects m...

Hi, i think the Commodore VIC20: Software Sprite Stack library is the best address for this. https://www.youtube.com/watch?v=UgynBsgwSyI Yes, I think that would be a good fit, Popeye and Pooyan also both used that (Popeye in heavily modified form to allow 3x2 character sprites). Also, TRSE maybe an...

Chat GPT says it's possible :D Creating a version of Bubble Bobble for the VIC-20 is an exciting project! The VIC-20 is a classic home computer that runs on the 6502 microprocessor. Developing a game like Bubble Bobble on this platform involves several key aspects: understanding the limitations of t...

That looks really impressive. I briefly played this on the Amiga and never imagined we'd have a Vic conversion. Congratulations on your achievement.

Out of interest and as something I've never really used. What's the benefits of using a monitor rather than just going straight to an assembler and using the VICE monitor.

I would suggest separating the problem into two parts..

1) Learning 6502
2) Learning to program the VIc hardware in 6502.

I would use the many web based resources (google 6502 assembler online) for part 1 then you will find part 2 much easier.

Attached with Makefile in the ZIP: 32k-loader.zip Assuming that all works since you've attached a make file. In Popeye I had an additional step of copying the bootstrap/relocate code to the cassette buffer as the first step and running everything from there otherwise it overwrote itself when reloca...

didn't realise this thread is nearly 9 years old - will be a relief to draw a line under it I imagine Yes. Everyone will be happy and I'll have forgotten about it three days later. arukanoido.demo.1689.zip fixes +24K mode and has +3K disabled. AFAIR +24K was preferred by most? I don't think many pe...

No, and you could possibly introduce more bugs - it's plenty smooth enough already. Leave that for your next game in 10 years time

nice, didn't notice the clash before but still plays smooth.

i don't much care for the flashing before a screen is shown. Even on a CRT it didn't look pleasing to my eyes. Reminded me of having a loose video cable
