Re: "Ultimate Expansion" - new firmware for FE3

By following the new building instructions for final-expansion.git visible in git view, I am now able to build the examples too. Thank you, this is great!
However, I find that the clonable final-expansion.git repo is now three commits behind what's shown in git view. Is this by intention?

Re: "Ultimate Expansion" - new firmware for FE3

Thanks for the link to the 1.5 download and the git clone URL. I have now managed to build all but the examples folder. It depends on some d64 tools that I don't have in my environment. (I had to download a snapshot of zippy.git and extract it in the zippy-folder since the zippy.git git module would...

Re: "Ultimate Expansion" - new firmware for FE3

I would like to test the new version so I have downloaded a snapshot of the 1.5 tagged commit. But I can't build it due to missing python stuff. How do I set up a working build environment? Alternatively, is there a pre-built zip for 1.5 somewhere that I've missed? Also, is it possible to clone the ...

Re: Ghost Town anyone?

I've been amusing myself with translating the VIC 20 16k version of Ghost Town posted in this thread from German into English. And I now think that I've got something worth sharing. I've played it through using the solution from the link in the first post so it "should work". I find the ga...

Re: Is VIA emulation cycle-exact in VICE xvic?

Sigh, you are correct. The "fixed" version fixes the line jitter but breaks the initial raster synchronization for NTSC xvic on the first run (It seems to be working for PAL xvic) Rerunning the program while it is still active breaks the raster synchronization for both PAL and NTSC. This h...

Re: Is VIA emulation cycle-exact in VICE xvic?

When I wrote the RNMI code I coded it on xvic as I didn't have a real vic20 of my own back then. So the code was glitch free on the version of xvic I used but not on real hardware as pointed out in this thread. A few years later I got hold of a real vic20 and could dig deeper into the observed jitte...

Use LOAD"",1,1 to load and SYS8192 to start. It loads to $2000-$4000 so it is a +8k game.

As far as I know the -aspect option is only available for the SDL-ui. The -config option combined with multiple config files is an option but is not as easy to manage as a single config file. As aspect ratio really is a property of the video mode I think that they should be associated. However, I ha...

Thanks for looking into the timer2 bug! Another thing, this is not a bug but more of a feature request regarding the "keep aspect ratio" option. This option is great but it only makes it possible to set the correct aspect ratio for one video mode, not all. I would like it if each video mod...

I think I've found a bug in the VIA-emulation regarding the behavior of the second timer. This has probably not anything to do with the bugs you have fixed, but anyhow.. When timer2 counts down to zero it continues into the negative so that it is possible to determine how many cycles ago it reached ...
