I hang out on Lemon once or twice a week. I come here about once every month or two.

I created a somewhat faster routine and actually creates more interesting patterns.

Code: Select all

10 A=162
20 PRINT CHR$(205+PEEK(A)AND1));:GOTO 20

Re: Porting to other machines?

Anybody here who has dabbled in porting VIC stuff to other machines? (64, A8, Oric, 2600/7800, Apple II or whatever) Any traps or tips to smooth the ride for an aspiring dabbler? The easiest target would be the C64 since it uses all of the same kernal calls and most of the graphics can be ported ov...

I laughed when I saw this a few days ago. The code is only slightly modified version of a 3 or 4 line program right out of the VIC-20 user manual. As memory serves the program was called "Random Maze" and it actually used a random statement to generate a 0 or a 1. Then it used two IF state...

need help with line-drawing routine

I realize there are sample source codes I can look at, but I was hoping somebody can just give me a brief explanation of the logic. Lets say you need to plot a line from 0,0 to 100,20 So you create a loop on the X axis from 0 to 100. No problem. How do you calculate the Y axis as you move along the ...

Could you tell us more about the scripting language? Well, it is sort of in limbo right now as I'm still experimenting with different concepts. But here's what I can tell you. Each command consists of 3 bytes. You have a command and then two arguments. To do something simple requires one commands s...

New graphics project

I'm writing this for the C64, but I thought I'd mention it over here because this could easily be ported to the VIC-20 and I wanted to see what kind of interest there would be. First let me explain where I'm going with this. I wanted to create a game very similar to "Amazing Breaker" which...

Here's a DASM ML PRINT@ routine that I made that resides in a little unused space in page2 RAM. To use it just use SYS679,X,Y:PRINT"text" Funny, I was thinking you could not use the SYS command with the register arguments on it except on the C128. I could have swore I tried that on the C6...

Yeah - I essentially learned BASIC from the book that came with my VIC-20. I think it is just fine for beginners, plus it has a lot of stuff that is specific to the VIC-20 (assuming that is the machine you are trying to learn to program for)

Actually, now I'm kind of wondering if it might actually be possible to simply redraw the entire screen each frame. There are a few things going for this idea. For one thing, I'm used to programming on the C64. But the VIC-20 has only about half as much data on the screen, plus the VIC-20 has a fast...

I have a 2003 PPC eMac. Should I keep it for future retro nostalgia?.. Good question. I'd say the original iMac with the colored plsatic will probably be collectible. Not sure about the eMac, though. That is a much less well-known machine. Of course last time I checked those machines with the built...

http://www.youtube.com/watch?v=bgTYLuCvzMA This was done bei streetuff of TRSI for the VIC-20 a while back. I had a chance to chat with him at the Nordlicht-demoparty this year asking him what kind of scrolling this uses. As I suspected he confirmed it uses 4 pixel scrolling. Wow! I've never seen t...

D) Shifting every pixel on the screen is probably too slow. It can be done vertically pretty quickly but I doubt horizontally. Yikes! I was afraid of that. Which brings up the question about if this game were to be done, how smoothly could it work? I wonder if we just moved a full 8-pixels at a tim...

I actually own one.

It is basically a Plus/4 without the built in (crappy) software and limited to 16K of RAM. Then shoved into a C64 style case with a different color. Oh.. and it has no user-port either, I believe.

Super Mario Bros for VIC-20

So here's a photo of the original Super Mario Bros. on the NES: http://i282.photobucket.com/albums/kk277/adric22/mario-original.gif Here's two photos of what it would look like on the VIC-20. http://i282.photobucket.com/albums/kk277/adric22/mario-vic20-multicolor.gif http://i282.photobucket.com/albu...
