I started playing ff7 and its been working fine but a few days ago the colour has changed in it such as characters shadows have turned from black to blue and the save/load screen has gone from blue to black. Various other colours seem different also.

Also resident evil 1 now flickers and sound is alot more muffled but a few days ago it was also fine.

Only thing I have done is updated apps from the app manager. Any ideas why this is happening? Both these were run at 900 MHz with psx4m version 0.4.4-1, frameskip 4 and cycle multiplier 2.
