Its me again =)
Ive tried it now with a Xstation, PSone, SCPH-5502, SCPH-7502
and a PS2 with modchip, on all consoles i have thid graphic bug =(

Amazing. It runs so well. I made it through the end on the SCPH-1000, shows lots of promise.

Bugs:
- Can't die (not even in pits)
- No boss (not yet implemented)
- Ring counter is weird if you loose rings


Cool, I tested it and it ran 100% on my scph5501 and on a PSone, the bugs you saw are ...
