Dreamcast GDI Compatibility List

[thedoctor45]

Has anyone been able to get Urban Chaos working in RC4?

Accoring to several compatibility lists it should be possible but I tried it with PAL and NTSC-U versions using optimized GDI format but only get a back screen - am I missing something here? I'm running this on an NTSC-J console btw? Does this game have a hardcoded region lock or something like 4 Wheel Thunder?
