@jpd002, can you make an issue label for this in the compat repo?

-Emotion Engine Cache

I will close this if it's done.

jpd002 commented 6 years ago

I've created the label: https://github.com/jpd002/Play-Compatibility/labels/issue-eecache. Not sure what is the extent of the issue, I guess some games rely on the fact that cache is not flushed (after a DMA transfer or something)?

jpd002 commented 6 years ago

Actually, we can keep this open since this is an actual emulation issue.

I did not enconter a game that rely on this yet, so far I can only test Evoltuion Snowboarding and the Homebrew. In Evolution Snowboarding, the cache is used during every cutscenes and in boss fights. Also I forget to mentioned that only the jap version of Dead or Alive 2 use the cache.
