Re: WIP: Bubble Bobble
The screenshot looks nice! This would be a very challenging project though. It kind of requires double buffering and it’s not the VIC’s strength because of the limited graphics memory.

Re: Prince of Persia
This looks fantastic! The wall perspective suits the hardware and hides the wide pixels nicely. Good choice to use hires.

Re: modded VIC 20 kernals?
Yeah, asking for the screen size returns hard coded values. It would have been nice if that was dynamic, but sadly too late.Merytsetesh wrote: ↑Thu Mar 14, 2024 12:21 pm If I had one mod for the VIC KERNAL, it would be to amend the screen routines to take account of variable dimensions instead of relying on the hardcoded values...

Re: 40- and 80-column expansions
I tried a couple of file browsers before I started making my own. I didn’t like the ones I tested because they didn’t feel intuitive to me. Lots of keys to remember or small inconveniences like for example CBM Command overwriting files without asking and using @: which triggers the dreadful 1541 bug...

Re: 40- and 80-column expansions
What application did you have in mind? I’m working on a file manager application for the C128 and I started considering to port it to the VIC20 since it doesn’t have many such applications. The standard screen would of course work but it would be nice to make use of additional hardware as well. I’m...

Re: 40- and 80-column expansions
Thanks for the detailed response. So the only problem would be to ensure that the running program can fit in the RAM that isn’t blocked by cartridge ROM.

40- and 80-column expansions
Did the 40- or 80-column expansions provide an alternate kernal ROM to allow them to be used by BASIC programs without modifications? Or did some of them, or none?

Re: Missing Pixels on screen??
All the pixels seems to be there. It’s just really blurry. The image quality isn’t great on an unmodded machine and a HDMI converter on top of that only can get worse.

Re: Vic20 Startup sequence to main screen Display? (was: Help Cartridge with a startup SOUND)
You seem to get as far as the VIC chip initialization since you have something displayed with the correct number of volumns and rows. If you type on the keyboard, does the screen change in any way as a response? You could try poking to change the border color or start a sound to see if only the disp...

Re: Suggestions, please!
Cheese and Onion should work on NTSC and is a cartridge game. H.E.R.O isn’t on cartridge, but has an attract mode. H3LP B0DG3 looks nice but I haven’t tried it. Super Monza also looks really nice.

Re: Is there sample VIC20 assembly doing wedges for BASIC?
I happen to be interested in this topic as well right now. What’s the issue with IF, THEN that needs special handling?
