The "Timer hack" feature is very buggy.

[ravope]

1. Timer hack doesn't have any effect until I enable the "Show FPS counter" (any form, so doesn't matter if FPS or Speed or Both, just choose any of them).

2. If both the timer hack and FPS counter are enabled, it makes the PPSSPP unusable, the games unplayable.
Tested with these games:

Vice City Stories:

If Timer hack and FPS counter are enabled, the PPSSPP freezes.

Colin McRae Rally 2005:

If Timer hack and FPS counter are enabled, the game will behave unexpectedly. Completely unplayable.
