I beat shadowrun for liked the mil time and i wanted to cheat some stats so I copied the smc and srm file to my desktop, opened the game with zsnes,
My save file loaded so I used the game genie support in there to get my stuff, saved and copied them back to the card and...
It worked YAY! Now i have my cheated save game in SnemulDs
