It uses PB7 indeed, and that's L - correct
The problem might indeed be the video source - if the video was deinterlaced, ie is now 25fps, then it will probably not work

Re: Help modifying C64 PAL code for NTSC machine
Generally on NTSC everything needs to be 20% percent faster (50Hz PAL vs 60Hz NTSC). So, when you you look at the code, there is one delay loop at $c044 which is called with different values in X at various places. So the first/easy attempt is to make this delay loop 20% faster (which then means all...

Re: Vic-20 mouse driver & demo program for NEOS mouse
I think you'll have to make sure to plug in the mouse before turning on the computer, and also make sure nothing else uses that joystickport before you run the NEOS program.... its really all a bit unstable

Re: Can you use a 6502B clocked at 1Mhz in a Vic20?
Its just the maximum clock rating, many MOS chips have this. In a VIC20 (or C64 for that matter) any "A" or "B" (and variants without) can be used

Re: Loading multiple data files into memory - HELP!!!
If you are using kernal, you can use one file and patch into the STOP vector (iirc) to update the progress bar (or do whatever during load)

Re: 1st ANNIVERSARY: Vision BASIC - New Paperback Edition - Fastest BASIC Compiler !
It's not as exaggerated as you might believe. It's not a question of believing. As said before, anything "hit" would be all across the usual places. Let alone "tremendous hit amongst Commodore 64 programmers, from beginners all the way up to seasoned coders." Vision BASIC does p...

Re: 1st ANNIVERSARY: Vision BASIC - New Paperback Edition - Fastest BASIC Compiler !
To be honest, most of the time i don't bother, because i am really not that interested in those new games. I see what is being released (and what is not) though :) As for this BASIC compiler, i might take a brief look at it and play around with it for a while, IF it'd be available for free. I wont p...

Re: 1st ANNIVERSARY: Vision BASIC - New Paperback Edition - Fastest BASIC Compiler !
In other words, don't expect all software to make its way there, especially if the developers step in. Am I wrong about this? Was the above just rhetoric on the part of their admins? a) CSDb is an archive, whatever is released gets an entry, sooner or later. That however doesn't necessarily mean th...

As soon as it becomes a "hit", it will happenCould it be that the vast majority of purchasers aren't interested in posting it to nefarious websites?

One doesn't contradict the other though. However, that there is no "crack" floating around anywhere, kinda tells you how much of a "hit" this isI would hope there's no trained version on csdb.dk!
Vision BASIC is an actual commercial product currently being sold.

Re: FPGA 6561 - PAL Questions
of course you can never guarantee that some funky demo isn't going to write unexpected stuff to unexpected locations Very often its not those "funky demos" - but old games. The Demos mostly are coded very clean and made by people who knew exactly what they are doing - other than the games...
