Emulator

What's the problem?
In both SSBM and Mario Superstar Baseball, I set up the game in whatever mode, and it gets stuck at the loading screen.

Dolphin version with the problem (as it appears in the title bar, Ex.: "R
4779" or "R 6403M"):
2.0 JIT64 DC

(optional) Dolphin version that does not have the problem:

Operating system and version:
32-bit or 64-bit:
64bit

Game ID (as it appears in game properties, Ex.: "GZ2P01" or "RSBE01"):
GALE01 and GYQE01

Build command-line (not on Windows):

Was the ISO a plain dump from disc, compressed and/or scrubbed?
Both were extracted from .r00 etc files

Please provide any additional information below.
I've tried various things such as changing the gfx settings, disabling the dual core thing, idle skipping, etc. I don't know if this is relevant, but in SSBM, the (m) code causes the game to crash right when I open it with various errors such as redundant MOV, and a couple others.
