VIC-20 core for the MIST FPGA board

A new core has been released for the MIST device a few days ago, and it is the VIC-20! http://666kb.com/i/cunefrh7q9t9ne0dl.jpg Scanlines are supported already, however a USB joystick is currently not supported, you have to use an Atari/Commodore-style jostick. Currently only the 16K-expanded VIC is...

For that matter, was VC-20 sold in Austria, German speaking parts of Switzerland, Luxembourg and so on? All I can confirm to you is that it was also sold in Austria under the name VC-20. I didn't know about the name VIC-20 until the mid-90s when I read about it on the internet. BTW, in the 80s I wo...

Wow, there are some more games from Aleksi Eeben! So far I only knew those from the Minigame contest.

The screenshots look great :shock: I'll have to try them out...

Did any of you talented VIC programmers ever talk to this guy and ask him how he's doing all this?

Apart from the fact I have not tested this program, something like this may work, possibly with some modifications: Almost! The first line should be "...GOTO 20,30", but then it works! Here's the loader for Donkey Kong: 1 ONAGOTO20,30 10 A=1:FORI=0TO5:POKE7680+I,PEEK(45+I):NEXT 15 LOAD&qu...

Re: How to run cartridge dumps in PRG format

To load a game, just load it ,8,1 and then start it with SYS64802 For a 16K image you need to load both files before the reset sys... One final qustion: how do I make a loader program for multipart games? For 8k carts, it looks like this: 0 IFA=1THENSYS64802 10 A=1:LOAD"CONGOB",8,1 But ho...

Pole Position is tricky to get to start - you need to disable IRQ. In VICE, you can use Alt+R to simulate a soft reset button. On a real VIC, try: POKE 37166,PEEK(37166) AND 127:SYS 64802 I've just tried this in VICE - and it works! :) Thank you all. Now I'll take a screwdriver, and let's see what ...

Re: How to run cartridge dumps in PRG format

Ok, thanks! Now I begin to understand how it all works :) I've now tried this in theory with VICE, and most of the games work beautifully. BTW, it took me some time to find out that for 16K carts you have to type NEW before loading the second part, because otherwise you get an "Out of memory&qu...

How to run cartridge dumps in PRG format

Hi folks, having read the recent discussion on the Atarisoft titles, I checked out the PRG format cartridge dumps at ftp.zimmers.net and decided to open this new topic... Now how do I get these games running on a real VIC? I assume that I simply have to LOAD these files, and they automatically get l...

I still have WinVice 1.7 from July 2001 - I'll send you this one if you want, just send me a PM with your mail address.

In the meantime, I've tried a few things... First, I've built the the Cinch cable adaptor, and with this, the picture is a little sharper and - as expected - the lines are even more visible. BTW, although my VIC is a 2-prong one, I've connected the "Low" Pin (Boray: I simply forgot about w...

You're a little lucky to load C64-saved data on a VIC, but generally it works. I've copied quite a number of *.PRG programs to tape now with Copy 190, and all of them work! In case that anyone is interested, here's a list of the games that I have got running from cassette with that method: Unexpand...

Hmm, and I thought that was a simple question... :? Ok, now I've tried the "C64 method" myself: as described, I transferred a VIC program to a C64 floppy disk (it can be a VIC 20 disk as well, there is no difference) using the Star Commander. Then, I ran the Copy 190 copy program on a C64 ...

Copy program for disk to tape transfer?

Hi all, I'm looking for a copy program running on the VIC (I have a 16K expansion if required) that can copy programs from floppy to tape . Where on the web can I find such a program? Or is there any trick for transferring machine-code programs from disk to tape? For a basic program, it's of course ...
