You're totally right, my DS cartridge was version 1.1 but I didn't check to make sure the rom was the same version, I just assumed the current online roms would have been updated. I downloaded a new rom and made sure it's rev 1, #1395 and was able to load my saves right away.

Thank you so much for your help!

I'm trying to import a save from my DS cartridge to play on DeSmuME. I exported the save using TWL on the 3DS via Homebrew. I imported the save onto my computer and into DeSmuME. The game itself ran and loaded the home screen and I got to the point where I can select one of my two save files to load. The game displays the preliminary save information (character name, in-game date), but I can't actually load either file. When I try, both save files give me an error message: "ARm9 Undefined Instruction Exception." I tried searching for this error and couldn't find anything.

The full error is:
ARm9 Undefined Instruction Exception.
ARM9 Program Counter: 0x01FF8050
ARM9 Instruction: 0xEC000002
ARM9: 0x01FF8048

The game is Harvest Moon DS (the final release version, not the glitchy one) and I'm running DeSmuME on a Mac

Here is a screenshot of the error: https://imgur.com/a/HIXo77A

Is there a reason this is happening and any way around it so that I can load the game?
