Last post on Forum64 by peiselulli on this was on Apr, 21st, where he replied to the question whether there were any news with "Leider bisher noch nicht ", which means "unfortunately not yet". Hopefully they can work something out still.

David van Scouten has posted a tutorial video on how to convert pictures using the tools (in german) here: https://odysee.com/@DvS_Arcade:b/VIC-20_Image-Tut:6 If anyone wants to try it themselves, this is a good starting point. Some things can be streamlined, but it certainly works the way he explai...

Steps to reproduce: please post the exact steps on the tracker :) (also pls try if you really have to remove the ini, or if starting with -default is good enough) Done, starting with -default is good enough (e.g. NTSC-interlace works). But starting with a saved .ini it crashes once interlace-mode i...

Tried the newer versions on both PAL and NTSC. I always have to press "Space" once the test finishes, then the VIC20 does a reset. Is that correct behaviour? It never finishes without pressing the spacebar on both PAL/NTSC. Attached please find my 4 result-files. While I got your attention...

This promises to be interesting:

Excellent analysis! Just playing around with your findings a little to see which portion of the video-RAM gets displayed. This seems to be just VM/2, right? In your example above for $9000 = 36 and $9002 = 22 (standard) the value for VM goes from $000 to $020 because only 16 (of the 22) chars of 2 c...

Just an SD2IEC-device.

Glad to have helped. But then what did you mean by "repair tool"?

Again, the MegaCart has a universal PAL/NTSC-fix for this. It removes a table for the registers $9000 to $900f, sets standard values using a ROM-call instead and just manually puts the needed values in the remaining registers thus not touching $9000 and $9001.

Strange, usually I can fix such issues (like no music at all), by holding CTRL and then selecting "RESET PREFS". Have you tried reseating the cart or using a different VIC-20? Maybe NVRAM is starting to go bad? nbla000 should know more.

The non-patched ROM-images are causing so much confusion nowadays and Mega-Cart has been out-of-production for so long that it would be nice to have an archive of the patched Mega-Cart ROM-images for the affected cartridges. I realize that some of the images require code outside their own ROM-images...

In any case if you don't have/use pi1541 but just sd2iec devices or CBM drives with JiffyDOS there is no reason to install SJLOAD09. Of course. I just wonder: There seems to be only one version of SJLOAD07. Is this PAL-only? A self hacking runtime code is not possible because when you write on $9E0...

Talking about Mega-Cart, the next SJLOAD version will check $ede4 in ROM and if the "installed" version is for that system uses it else uses kernal load, so you may install the PAL version but if you use a NTSC machine, the SYS40000 do nothing and LOAD works anyway (kernal protocol). To b...

Are the NTSC- and PAL-variants very different? Since I use my Mega-Cart on both machines it would be nice to have a "universal"-version (V9) provided it still fits in the free space on the Mega-Cart. Also: obvious less bug reports from users with a version that checks for PAL/NTSC-device (...

Yes, this is most definitely the same effect. I just found that back in 2018, Mike and I discussed this and I adapted/improved the test-program by Lance to better analyze the problem. Try the attached D64. Should work with or without expansion. It basically fills the screen with chars 0-255 and each...
