Re: Forum moved to new host
Here's a draft of a refurbished VIC-20 logo for Denial, with the perspective being correctly applied this time: https://dateipfa.de/.Public/denial/images/tools/vic-20.png I can replace the cyan background with any other background colour, and would also add in the Denial caption. Internal links will...

As Parkinson's last law states, postponement is the deadliest form of refusal. If this had been a real prototype of WoW, I suppose the people concerned would have pulled out all the stops to confirm its existence. OTOH, if it wasn't the case, the natural reaction - after causing all the fuss - would...

Nigel, regarding news for the VIC-20, just take a look at the newest postings in the Announcements section. There have been a quite a lot of interesting developments in the last few weeks. They're already there, literally on a silver platter. Those announcements are however usually quite short, and ...

Re: fcbpaint - graphics editor with drawable inline color sp
Noted but I have yet to come up with a behaviour that is useful. I guess it will have to adapt to the actual pixel shown. It doesn't do that now. The cursor in MINIPAINT is a frame around the current pixel. It is drawn from the two global colours which have the lowest and highest brightness, respec...

Re: fcbpaint - graphics editor with drawable inline color sp
I see. Scheduling the instructions should already be quite difficult as is. ... For another few things: - I could make fcbpaint crash by tapping RESTORE several times in the preview. Upon returning to the editor, the VIC-20 would end up in a perpetual warm start of BASIC (a blinking 'READY.' in the ...

Re: fcbpaint - graphics editor with drawable inline color sp
Hi, -- in some cases splits as close as 2 or 2.5 chars apart are allowed. from what I gathered, the placement of split 2.5 chars apart relies on the ZP being initialised to $00 .. $FF. That means a load instruction which would normally take 2 cycles in immediate mode can be replaced by one on the ze...

Re: How to implement WHILE-WEND
Waterloo BASIC speeds up the processing of its program flow control commands this way. This applies to IF blocks, loop constructs and procedure calls. I briefly mentioned the 3-byte tokens used for that purpose in a posting here . From what I remember, the extension does not go over the whole progra...

This answer's quite late, and I am not being quite sure, whether the project has been continued in the meantime, but nonetheless ... I haven't yet learned how to save a file in VIC-20 format yet. That will be my next challenge. My initial goal was to be able to open an image file, select a portion o...

My mistake. Not a buffer, but the memory area 664-767. The addresses from 659 to 672 inclusive are used by the KERNAL for the Pseudo 6551 registers. There's a 'free' area from 673 upwards, up to address 767 (the so-called program indirects). Actually, the Super Expander uses that area for workspace...

I removed the secret in Doom that was screwing up a level, but I haven't integrated the loading screen that Mike sent me. I need to make it load the game when you press a key. Would the main program of VIC Doom (temporarily) fit into memory behind the already loaded splash screen (i.e. after ~$2100...

I also just implemented POKE 808,100 to disable RUN STOP/RESTORE. Does anybody here know of any negative effects of using that POKE? It's surely one of those POKEs that were published by dozens-a-mill in the magazines of those days. 808/809 is the STOP vector, and points to the routine that is supp...

Nice! :) German C128s also have a second character-set with slim chars (DIN-mode). When using this the characters look very much like on the VIC-20. Should be no big issue to dump the original charset of the VIC-20 and include it so it can be copied to the VDC RAM. I once 'emulated' a VIC-20 program...
