Emulator

Starting with 3.5-367 (rca46a34dde49347f320e8cb79cdca8df7a022657), Metroid Prime 3 (RM3E01), Metroid Prime 3 Trilogy (R3ME01), and the Metroid Prime Trilogy menus suffer from framelimiter problems. The VPS is 60, and the speed shows 100%, yet the game runs at 10-20fps with very slow gameplay. It's unplayable. Adjusting the framelimiter has no effect, and turning it off makes the game run way too fast on my system. I've tried JIT/JIT64, Vbeam (made it worse), all graphics backends, MMU Speed Hack, EFB to Tex/Ram, and even Real XFB. No dice.

All of Metroid Prime 3 is affected, both menus and gameplay. Metroid Prime Trilogy is rather weird. Metroid Prime 1 Tri and Metroid Prime 2 Tri are unaffected. But the Trilogy menus and Metroid Prime 3 Tri both have the problem. I have no idea why this is the case.

3.5-375 is worse than 3.5-367. 3.5-367 runs at 20fps, while 3.5-375 runs at 13-14fps. I didn't do testing to confirm it, but that since it started with the IPC-HLE merger, the second IPC-HLE hacks change made it worse.
