Looking great - very smooth.
I pressed the L key and it locked up, perhaps that's normal.
Vice 3.1 snapshot attached anyway.

Re: In the making: Arukanoido – an Arkanoid clone
I had a similar issue when developing Popeye. It would sometimes get stuck. In the end I reorganised the memory map to put all writeable values on a single data segment then set up vice watches to alert if writing outside of that segment. I also set up an auto play mode with infinite lives. Then I s...

Re: Cartridges!!!
As a teenager I had Jelly Monsters and Super-Lander.
I too had to have the original cartridge even though I have them on the mega-cart, just for the box, artwork and smell.

Re: VIC20 Jailbar removal & improved S-video modification.
Thanks, I'm going to try it out.
I have a few Vic-20s and will keep most with the blurry "period-correct" look, but will try this on one of them for sure.

Re: Great gift for VIC-20 freaks
Nice idea.
Might be useful to also have pages with grids for designing user-defined-characters and screen layouts?

Re: Mega-cart issues?
Good idea about the cart extender. I don't have one so I'll have to see if any are listed on ebay or find if anyone is producing contemporary versions. My VIC-Rabbit has a "passthru" cart connector, so I'll play with that too, see if it helps. If you can't get any joy with the "VIC-R...

Re: Mega-cart issues?
I believe you should be able to prevent it from AutoStarting by using a cartridge port extender that allows you to turn it off? Then you could try switching it in and running the program again?

Re: Mega-cart issues?
fair enough, only skipped through.
You can try unzipping and running the attached mega-cart repair program on the Vic. Can't remember where I got it, but it has rescued mine a couple of times.

Re: Most recent Gamebase with Newest VIC-20 Games?
Just a suggestion but it would be nice to have this project re-platformed into an online offering rather than something you have to download and install on a Windows only machine. I took a look at it once and easily generated a web front-end in ASP.net by converting the access database to SQL. It co...

GPT-4 Can you show me how to add two sixteen-bit numbers in 6502 assembly language? Certainly! Adding two 16-bit numbers in 6502 assembly language involves a process called "16-bit addition with carry." You'll need to split each 16-bit number into two 8-bit numbers (low byte and high byte...
Re: Targ
I've never Spectar before - looks quite good.
On a related side note: It's funny how game programmers of the era thought that an ascending/descending frequency-sweep was a cool sound effect. Seems something particularly prevalent on the Vic.
