I share these IPS patches. They turn on R800 (if it's found...) and work correctly.

Dragon Slayer 6 - R800 OK_IPS_PATCH

Fray MSX2 R800 OK_IPS_PATCH

Psycho World - R800 OK_IPS_PATCH

Undeadline - R800 OK_IPS_PATCH

I hope you like it!!

Victor, Line interrupt occurs higher in R800 mode, or have you found a solution for it to happen in the same line with Undeadline?

Victor's patch for Undeadline indeed looks way cleaner than the previous version I've already seen! In this previous version, the display was flickering badly between the score and game areas, now there are only a few lines, that remain black and do not flicker!

My understanding at the time was that the VPD in R800 mode was slower to transfer the sprite datas to VRAM, causing it to miss the expected interrupt line. Wondering how Victor did to fix that ? (maybe just shifting the interrupt line down so that it's never missed?).

Yes... You're right... I'll check that...

I optimized Undeadline and the game is really faster but because of interrupt issue I did not release it. This version interests you?

The idea I had in mind to fix that (a long time ago): switch CPU to Z80 mode before to transfers sprites to VRAM, and switch back to R800 after that (switching CPU also takes some time, so not sure that this will work).

You're right.. the issue is the time with the OUTIs with the sprites in line interrupt... but just writting a RET in FD9Fh is works better!! the line is two or three pixels higher..

The real problem is that this game doesn't manage correctly the interrupts....
