Other notes

As mentioned, the game boots when "Card read DMA" is off. Interestingly, a previously AP-patched trimmed ROM appeared to boot without additional adjustments.

I am experiencing the same issue as above. My USA dump version boots with DMA but it freezes entering certain places like the top of the lighthouse in Lodestar. I tried switching all settings but only DMA=off solves it. I hope it helps.

clear the patch and fat caches

RocketRobz commented 3 years ago

Don't remember if this game got added to the DMA blacklist, but since turning it off fixes this, this will be closed now.
