Denial

Thanks Beamrider, that is consistent with what I have seen.

Do coders use multiple interrupts per screen or do they tend to keep control of the raster within the one interrput for the whole visible screen. (Does that make sense?)

I was wondering whether anyone had modified it to interface to C via cc65 or do you have to code in ca65 or BASIC?

I've played with this raster interrupt some more, and when I comment out the sync code in the interrupt code after the timer has been setup and enabled I get horizontal jitter. It appears that there is cycle variation in the timing of when the IRQ occurs. It doesn't appear to be totally stable as Ka...

Sorry to dredge up an old thread and hijack it, but this is the topic I wanted to ask about. I've implemented Marko Makela's stable raster routine from the original article in C-Hacking Issue #10 in cc65. I've modified it a bit to move the effect on the screen (and added it to my existing test code)...

Beyond hope, actually. It's impossible to type in the program from this scan. Richard sent me a version of the program that had been typed in, however with the difficulty in reading the scan it had many errors and they were what I was trying to work out using CBM Prg Studio. The 3D maze program is ...

Home Computing Weekly, Issue 20, 19 July 1983, Page 30, Mazes make the game...here's how to construct them. https://archive.org/stream/home-computing-weekly-020?ui=embed The text is really small and the scan is low resolution. I haven't been able to find a better quality scan of it. I printed it out...

Hi All, I'm the user who asked Arthur to add the Vic20 tokens the CBM Studio. I didn't even know they were different until I started helping another Vic20 user who hosts a site of type-in programs to debug one of his listings that used a Super Expander and was not working. I decided to use CBM Prg S...

Thanks for the reply Kweepa.

If I uncomment them, it's the first one the code comes across in main().

This code is a mishmash of ideas that I've been working on for the past few years. It was me learning how to program for the VIC-20 hardware.

I'm finally putting out a call for help. Over the past few years I have been trying, on and off, to get some code that I was working on prior to Uz passing the CC65 maintenance on. Initially I had issues with actually building the program, as the config file changed, and way custom startup code chan...

I recently came across this game while surfing through Boray's website and became quite addicted to it. It's easy to just sit and play. Anyway, I came across what I think is a bug. I like how the game shows you where you have been winning hands and I noticed I hadn't won with a straight very often s...

I now have it writing out the MiniGrafik multicolour grey scale images. No fancies for selecting colours yet.

Nearly another year down the track, and still I continue to plug away at my plug-in. :lol: I thought it was time I posted an update. I've cleaned up to code a bit and have got it correctly writing out image files (I say correctly, however I think I still have it set so that it auto loads and runs in...

It has been quite a while since I've had time to develop this plugin further. I was quite surprised at the interest in my initial trials. I sense from Mike that his preference is to have Minigrafik development done using Minipaint, and I can respect that. However, the sort of development I'm looking...

I got the first two OK...bit rusty on the Apple II, however this one stumped me. I wasn't aware of any palettes that had transparency. I had to do some research and I found it. ;^) I can't claim it though, as I didn't know it.

In my case, you can see from the 'ls' under my error code, that the file it was saying wasn't there was in fact there.
