Hi!
This game has an issue with jump tables not found like a couple of other games. It hangs the emulator for a fairly long amount of time, but it is still processing and progressing in the background.
I'd recommend trying with PPU fast so you can get ingame.
I have confirmed the demo goes ingame after some patience here

Please try leaving the game/emulator open for an extended period of time and report back if you can. Thanks!
As for now, I will move this to general discussion as nothing reports are taken very seriously. If it is left open for a very very long period of time and still fails to boot, I will move this back to the nothing category.
