Akiba's Trip Undead & Undressed [BLUS31425]

Fixed by Jarves.

Settings:

Both recompilers
OpenGL with GPU Texture Scaling and Invalidate Cache Every Frame(not entirely sure this is necessary)

Played for about an hour, no crashes, speed never dips to unplayable territory(10fps is the lowest I've seen, with several dozen characters moving around on screen at once, and even then it doesn't feel that slow). Would absolutely call this playable.
