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: Suggestions, please!

I always found "Capture the flag" somewhat impressive, being such an early title with first person 3D

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...

Re: 1st ANNIVERSARY: Vision BASIC - New Paperback Edition - Fastest BASIC Compiler !

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

Re: 1st ANNIVERSARY: Vision BASIC - New Paperback Edition - Fastest BASIC Compiler !

I would hope there's no trained version on csdb.dk!

Vision BASIC is an actual commercial product currently being sold.
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 is :)

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...

Re: FPGA 6561 - PAL Questions

I think it would be fun to have it available, assuming it doesn't break anything. If i learned one thing in 25+ years of fiddling with emulation, it is: if it doesnt work 100% exactly like the real thing, it *will* break something. And yes, that includes everything "irrelevant" or "u...

Re: FPGA 6561 - PAL Questions

As said before, contact that "Tobias" guy from Forum64 - he has the numbers in a nice table, and they arent in this weird form that VICE expects. I just randomly added or subtracted 180° or 360° or whatever until the VICE color generator produced the expected result - no idea why exactly i...
