I Have only tested this problem with Tomb Raider 2 & 3 (only roms I have on my device)
I am still having problems with the stop and start buttons on my Galaxy S3 and my Transformer Prime. I have loaded game from memory card which works OK with stop start buttons but after saving game with FPSCE the save does not allow access to stop start buttons and game freezes.
I thought originally it was old save states but it also seems to occur when saving new saves from memory card. The save created immediately after the load from memory card seems to work OK but subsequent saves revert back to same problem. I have also tried re installing , reset and using both opengl and software mode. I have also tried many save state paths on internal memory and sdcards.
The problem occurs on both my phone and tab it therefore may be just relevant to the 2 Tomb Raider games I am using, however both the same roms worked perfectly well in previous versions of FPSCE.
Are there any previous versions of the android version available to test ? (difficult with upgrades via play store)
Edit: Some of the sound effects also do not seem to work after save. When I originally got this ISO to work I had to convert XA video streams in pocket ISO - I do not know if it may be video cuts between saves that may be affecting app
Any ideas welcome.
