i just want to continue earthbound halloween hack on my 3ds but i can't because of the kill ending. I want to port the save from my computer but idk where it is. Help would be appreciated.
Well… this depends on the version you are using
Test with snes9x version 1.58 from openSUSE "emulators" repository with snes9x-gtk:
Writes saves by default to the location of the current ROM.
Test with snes9x version 1.60 for Windows 64-bit (with wine):
Writes saves by default to the location of snes9x-x64.exe in the sub-directory "Saves"
Another version may have different default locations. The settings menu should tell you the current location for saves, savestates, screenshots…
Savestates are not compatible between 3DS and PC versions of snes9x, but the normal SRAM saves are. In the worst case, if you can't find out the location, search for "*.srm" files on your computer.
For the 3DS version saves are stored at the location of the current ROM.
