Just to let you guys know, saving to the memory card works fine in MGS for me. Only when I try to use Fpse's save system i experience crashes and no sound.
Also after clearing the data as I was instructed to fix the overlays I noticed significant speed increase in landscape mode.
To get full gameplay speed in MGS I had to over clock my droid to 1.0 Ghz
Hope this helps some people, keep up the good work Schtruck!
