Thank you, this has pointed me in the right direction.

Do you know what sort of tool would allow me to extract my save and inject it back? I would be interested in doing something like this.

Everything I had accomplished in the save file was still there. ie. I had all my old pokemon and my hall of fame record was untouched

Hello, I see these forums are hardly used but I'm not sure where else I could ask this. So when I was in middle school I played a copy of Pokemon Ruby version. A friend at school said he could get me any pokemon I wanted if I let him borrow my game so I gave it to him and when he returned it I had pretty much everything. 99 of every item and TM. Multiple shiny legendaries. My pokedex was completed (386) and he also changed my player name. I just want to know how this is possible - I had a cartridge.
