Re: Conversion of VIC-SSS-MMX to CBM prg Studio
You may need to add conditionals for non MC use as I wasn't interested in that.

Re: Conversion of VIC-SSS-MMX to CBM prg Studio
The API as it stands doesn't really support multi-color sprites per se, they unexpectedly disappear behind background graphics because of the simple XOR. See the original 2013 Pooyan. I made some changes for Pooyan 2015. http://sleepingelephant.com/ipw-web/bulletin/bb/viewtopic.php?p=80327#p80327 Al...

Re: Video noise on VIC-20
Thanks for this.
I guess there's only one Poland based Commodore PSU supplier on E-Bay, so it's worth spreading the word that these are not suitable for the Vic-20.
Assuming it works okay on the C64?

If you were so inclined, you could modify the above and join two halves with a ribbon connector?

Re: Commodore Vic-20 with a Blank screen?
Okay - sounds like it may be the Vic chip and the BASIC ROM in that case, but honestly, it could be a lot of things. You really need a known working machine into which you can try the suspect ICs.

Re: Commodore Vic-20 with a Blank screen?
Since you can hear sound with the cartridge, switch it on and type: poke 36876, 220 : poke 36878,15 <Press return> If you can here a sound then the KERNEL ROM and BASIC are working otherwise they are good candidates to swap. But most likely it's the Vic chip since you get no display running the game...

Re: Vic 20 Noob: trying to load Bewitched
[...] I'm still getting a little bit of fuzz though, [...] You should check out the plethora of threads regarding a S-Video mod on the VIC-20 here in Denial. :wink: I will do that, maybe a future mini project for me. The picture quality is acceptable but there's room for improvement. I actually pre...

Re: Vic 20 Noob: trying to load Bewitched
I've got Bewitched to work! One important thing I didn't mention was I had a Simplex Data 16k memory pack plugged in, it hadn't occurred to me it could affect a cassette drive motor control! Removing the memory expansion allowed the game to load fully. I've now read that having too much ram can sto...

Re: Vic 20 Noob: trying to load Bewitched
Welcome to the forum and the world of the Vic. I'd start by cleaning the tape heads and moving the cassette away from the TV if that doesn't work it could be the tape itself or even your Vic. Unless you have access to other hardware it's difficult to determine the issue. To enjoy the Vic-20 without ...

These are by far the best soldering videos I've seen (professionally produced). This is lesson 9 but all 9 are worth watching.

Re: What would be a good game for...
If your talking about the general public I'd say it would have to be Space Invaders (Avenger is coloured) or perhaps Donkey Kong?
