So now it works well, but it fails the unibios CRC check for one of the roms...
Guess I'll EP rom replace the other P rom as well and see if that fixes that...
some other day.
Happy enough for today.
Never mind, looks like everything is fine. I have the same CRC as this dude:

Guess I just have an old unibios.
Nice!
Then everything works great!
The CRC checks are fiddly as is. If the cart connector is dirty, or even slightly misaligned, I’ve had failed CRC checks when the game plays perfectly. Reseat the cart and suddenly it passes.
