Yes, i believe it is too! I manage to get it to boot and it froze on certain options i started to get it to work then it froze when i completed a level.
it's strange as i tried it on a new dreamcast i just bought today along with it, the dreamcast is refurbded and modded from a respectable seller on ebay. i tested it on my Treamcast and it works fine, but im confused as every other game ive tried on this new system runs fine with no read errors but all signs point to it being the dreamcast its self :/.
Silly question but could it be the custom bios that is the problem?
