Yes, you're right, I wasn't specifically interested in using the RAM disk features. I'm glad Sven is sorting it out.

Re: Circle Routine with Aspect Ratio

There's this video from a a scener which usually does 8088 assembler code, showing his adventure to draw ellipses with a generic orientation regarding the screen axes. He did a comprehensive work. https://www.youtube.com/watch?v=d8ulXJZD0P8 I did a standard bresenham circle for a game, but to comput...

Re: Using FE3RD in VICE (was: Re: FE3 RAM Disk)

Yes, this issue looks similar to the one I had. I'm attaching an image depicting Mike's instructions. Click on it to see it a little larger. 2023-08-16 (2).png In order to study or use this program, I think there's little advantage compared to the standard FE3 ROM, where it ended up being integrated...

Re: Bad Apple

Thank you. I used VirtualDub (same as in Nuvie movies) to convert the video to a bmp sequence. Then a python script for Gimp to resize and convert the bitmaps to black&white images of 14x16 chars (112x128 pixels) for the VIC, and then export to RLA compressed binary files. This is 224 chars, sli...

Re: Vic-20 mouse driver & demo program for NEOS mouse

An update about my Neos mouse: it seems to work well with my Final Expansion Alpha plugged in. Whileas the other day when I was trying it with MCES 37kB RAM (which overlaps IO area) the mouse driver sometimes started fine, but sometimes refused to start and showed the wrong behaviour I tried to expl...

Re: Vic-20 mouse driver & demo program for NEOS mouse

I wasn't capturing the mouse Alt-M, however, it still doesn't work. The values stop increasing but then remain constant.
However, I got a real Neos mouse from ebay and sometimes it works fine, sometimes it just does the increasing coordinates thing.
Anyway, it's cool.

Re: Vic-20 mouse driver & demo program for NEOS mouse

This is interesting. But I was unable to run the sample programs in VICE.
The program displaying the mouse coordinates shows both values incrementing regardless of the device selection in the Control port box.
Maybe I missed some step or something has changed in the emulator.

Re: Happy Easter Greetings from Revision 2023!

I tried to watch the stream on friday but I had some difficulties as I'm used to Youtube and Twitch, which lower image quality as long as needed.
Then on saturday evening I was busy and forgot about it, I hope they upload the video somewhere.

Re: Using FE3RD in VICE (was: Re: FE3 RAM Disk)

I don't know how to enable the FE extension in VICE, I thought it was enough to tick the checkbox "Enable Final Expansion image write back". I've noticed that the extension isn't actually activated, the RAM bank select in the RAM Disk application does nothing, all the writes go to the same...

Re: A good book or written piece about large resolutions on VIC?

The maximum columns I got with a 1084 was 27-28. Maybe even 29 columns, but at this point the image width was so narrow that the whole borders fit inside the screen and the edges of the CRT had an uncomfortable white glow. It's better to stick to 26 columns for PAL, anyway regular TVs can't adjust t...
