Started coding a demo with a friend of mine.
I made a part that uses raster interrupts and gives the illusion that the picture is up in the border.
- Opening the borders
- Changing the border colour midway
- Using NOPs to get a stable rastersplit
- Sprites in the border
- Fixing the sprite mirroring in the bottom part
- Learning a lot about bad raster lines, I had to make a lot of workarounds to get it working
Hopefully I’ve got some rastertime left to play music. But I learned a lot!
UPDATE: Yes also with SID music!

Not shown: Bad raster lines, split colors background and bordercolor.
Maybe I’ll add these later.

Sprite multiplexing done and self modifying code.
