I am looking for light pen software for the vic-20 or the C-64. I purchased something on eBay and the box came with a light pen but WITHOUT the software disk.

I am looking for graphics software or anything that you might suggest.

Ok... That EOR 0111 or EOR 1000 trick is VERY TERSE and COOL!!!

I think this is a concept I need to apply to my style. Many thanks.

Thank you, Robert. You pretty much confirmed my methodology. I did not switch direction in such a nice way as your XOR solution. I don't completely understand it right now but I will go through the math of it and see how the XOR switches direction. This seems like it could save me quite a few cycles...

I will check it out when I get home. Do you have the source you would like to include?

Yes, I know of Robert's routine. It is very brilliant and broad in its application.

I want to be much less broad, stay within the unexpanded vic, and experience developing my own routines.

Looking back at what I typed.... :P I have come up with my own routines in ML but I will try to restate my question. I wanted to move a 2 pixel by 2 pixel "ball" around the screen in a smooth fashion. Imagine a paddle at the bottom of the screen and a ball being launched from this point. T...

I am not sure what the protocol is around here so I don't mean to be offensive. Is there a way you could distribute the numerical definitions of each character? There may be a few I would like to copy for some programs. Thanks. Jonathan BTW, the question mark was not altered for a reason. I work on ...

I am trying to come up with a nice ML routine that will shift a 2x2 ball in a hi-res fashion. The ball is multi colored so I want to shift 2 bits. The X,Y deltas will be as follows 2 bits, 2 bits 2 bits, 4 bits 2 bits, 3 bits The X move is fairly easy with shifts I am looking for suggestions on a te...

I am looking for the original magazine.

If you want an original mag to complete a set then sorry, I have no originals.

I am looking for the following Compute! Gazette. I have issues to trade or I would purchase.

Hello everyone. I know that Compute!'s Gazette eventually came up with a monthly disk. But how about those early issues? :-) Does anyone know of a repository containing these programs? I am HOPING someone has typed them in at some point. I have been trying to complete my Gazette collection that rela...

LOL. My sprites I am creating and the flow of the game is not too intense so I am pretty happy with things so far. It has been fun learning and developing my own routines. I figure that once I get this down I will start using Robert's API. Yeah, it only took me 24-years to get rid of the flicker! :P...

Grin..... Yes, it is. Once I stepped into the routine it became clear.

Hello everyone. I am including my trace session from a debugging session and I have a strange side effect that I cannot begin to explain. Any help would be appreciated. Things go nicely in PC 108E, 1090, 1093. Once 1095 is executed (STA $0364,Y) the PC gets reset to FF73 This makes NO SENSE. Help!! ...

I am writing my first game with smooth scrolling sprites. My current sprite 2 characters sitting side by side in multi-color mode. In essence 8x8 (actual 16x8) The method I took was to define the graphics and then at the beginning of the program use the LSR ROR ROR to build my 4 possible sprites. Th...
