Re: Newly Found 40+ Year-Old VIC-20 Easter Eggs by Commodore Programmer Andy Finkel

If you hit C= Shift and CTRL on the title screen of Omega Race it lists out a title screen with Andy Finkel and his associate after you release the keys. He also pointed out that you can press shift F1(F2) and get extra lives on Omega Race which I didn't know either. The Loan calculator from the 6 p...

Re: A New Draft

This looks pretty cool! I guess the best way to find errors in the book would be to use it. I have a comb binding machine which makes "lay flat" books a like the original programmers reference guide. Maybe, with permission from the author, I'll print one for myself? I think I even have som...

Re: ANY LANGUAGE OK!

I have an idea! If we make the English translation vague and rather ambiguous, it'll make the translations seem more clear! Welcome to a word tribe called 'denial'. The Commodore VIC-20 is the only brand to speak of. Super happy #1 star king computational devices. Typing vigorously, turning on your ...

Re: Anyone have success running "PET LOADER"

Well, I was thinking one might add a basic wedge. This could intercept the pokes of a given range and simply append the range to the "correct" range; or the specific address to be correct. Then change the background and foreground to black. Change the text to green or white. Tah Dah! How c...

Re:

Actually, the start address is $BA86. The ROM dump is for most part empty all the way up to $B088, where some text in German appears: "Ein gabe im format". The screen is set up based on values stored in $B480 and onwards, which is copied to $2680 (RAM). In theory, it would be enough to: P...

Re: My BASIC Roguelike

One thing you could do to offset balance or ease would be to have some alien attack mini game thrown in there... that would be pretty darn cool! Whatever they hit gets destroyed in the main game or something like that. How is this game progressing btw? I hadn't played it for a while and today I was ...

Re: How to read bits from tape

@Forbidden64, was him Luigi Di Fraia ? Ya, that is the guy. Somewhere, i can't find it, he did a complete analysis of Rabbit's fast loader for the VIC-20. Interestingly though, the 6522 seems to allow for automatic control of all this stuff. They just didn't use it likely because Chuck Peddle had h...

Re: Using FAT-40 to circumvent LIST protections

Ah, I see. Well, you certainly know your 40 column editors! While I am at it, do you know of any 40 column word processor type things for the NTSC VIC? One that can save SEQ files?

Re: Using FAT-40 to circumvent LIST protections

Interesting. This seems to be FAT-40 from Zimmers.net: http://www.zimmers.net/anonftp/pub/cbm/vic20/utilities/8k/index.html Apparantly someone had fixed this for PAL and the version you have is back-fixed to NTSC. The original however was always NTSC. It was called VIC-40 and is from Ahoy Magazine ...

Re: Using FAT-40 to circumvent LIST protections

Has this been released? I'm always interested in 40-column-editors. The ones out there all have some problem or another (either they do too little or too much). Actually, I am not sure where I got it. A few years ago, called 'FAT-40 4609.prg'. I modified it for use with NTSC televisions, installed ...

Re: CBM DOS: How to read directory in raw format?

Hi there, am trying to read a directory but I don't want to process the BASIC listing version. Using a secondary address of $60 was supposed to help with that but I still get the BASIC thing. Any ideas? My advice would be to stick with the block commands themselves. In addition, I have heard it men...

Re: Relocating basic?

Looks spot on. 27 = 1B, 255 = FF
1BFF = 7167

Neat experiment. At first I thought ... Oh no, another program that doesn't work on NTSC. Then I saw what you were doing, pretty cool experiment!

Using FAT-40 to circumvent LIST protections

There is another truly bizarre thing I observed today. Once again on my adventure of converting a huge number of UK programs over to NTSC...the game DOTMAN does something in basic(among many astonishing things) that is truly off the charts weird for cursor control. I am wondering what other things t...
