I fixed most of the problems and added different versions
The differences are overworld,status bar
I did not encounter major problems that hinder the experience
To fix slowdown you must use retroarch emulator core snes x 2010 pc and android  then select option and reduce slowdown then click compatible or max
Please use this hack on a clean rom+header
If find a problem, please make sure the ROM is clean, the emulator is properly running, and also make sure that the patch is properly applied
Do not use srm in the emulator as that spoils the game
Please if find problem Write it + level Name
Enjoy
