Does it work in VICE?

If my VIC-20 Ultimate Expander is working correctly, I will show the demo at the next FCUG meeting.tokra wrote:Requirements: Real NTSC VIC-20 (wont't run on emulators) with 24K RAM expansion (32K for converters)

Thanks, but no: PAL is completely impossible, since the VIC-6561 does not support the interlace-feature. Only the VIC-6560 has that one.
So while PAL has a larger overall display area (208x256) NTSC beats that by using interlace which adds flicker to the picture. Take your pick.
The screenshot above probably is only one half picture, it's pretty hard to take a screenshot when the picture frequency is 30 Hz instead of 60 Hz.

This release in certain part is also a response to the whining, that tokra and I got from NTSC users, saying they wouldn't be able to run MAXIGRAFIK, and later, the MFLI pictures on their VIC-20's.
So by now, PAL users had MAXIGRAFIK and MFLI available at 208x256, NTSC users now have MIFLI available, at 168x384i. Both offer a comparable, and (in case of NTSC, near) a full-screen, colourful and fully bitmapped graphics mode. For the more adventurous there's VFLI (PAL) available with a hardware mod - a NTSC variant, VIFLI, also with 168x384i could be done, but quite possibly will remain in the drawer for the next time.
Just to say it again - the tools are out there now. Take them, and develop something nice with them by yourselves!

Please find a YouTube Link for your viewing pleasure. Took some time to record and convert so it would look good on YouTube. I also updated the download-archive, since I found a minor bug in the loader. It would only work on 32K not 24K-expansions before. Since some fastloaders use BLK5 these were affected as well.
Witzo: No, just some random internet cat, sadly

Thanks! Very cool! I immediately posted the video link on Facebook.
