Stefano, my code generates 2 different vsyncs, one for odd fields and one for even fields. That makes it easy to know which phase you're in and which part of the graphics should be used.

The keyboard OVERLAY needs to be updated to get the correct keywords for the 8k ROM. The matrix is the same. A simple sticker would be enough.

Here is my post about interlace graphics

A long time ago I made real interlace mode with source code, available somewhere on this forum, search for ilena.

Ah, nice to see someone expanding an old game I did long ago
I really like the side-info, and UDG is very luxurious. Good work!

Moggy, stereo is indeed possible but at reduced samplerate. I don't remember if shuffling data from the card was a bottleneck or not.

Wow, another user! This makes me really glad

I believe this is what you request onfo about: viewtopic.php?f=6&t=1827&hilit=Annivers ... lKollTroll

There is a program to convert audio to the format needed by this player. Have a look at the description at guthub, it tells most you would need to know.

Try CONFIG "M=H" before the program...
EDIT: now included in the release-files.
