I've forgotten about that game. I noticed the original version has no region protection, but the "Wonder Price Version" is not confirmed for having no region protection. Any idea for sure if it is or isn't compatible with NTSC?
Edit: Actually, scratch that. I just saw on a shmup forum that it apparently is region free. May order this one as well.
It definitely is. I have the Wonder Price version and it plays in my US 360.
