Summer vacation has started for me and I decided to begin collecting a physical copy of each Pokemon all on my own (no trading with others except npc's) once again. I decided to start with FR/LG and then transfer those to B/W2. My problem is that I used a gameshark on my LG cartridge (I know the rules say not to discuss gameshark, but I believe this is a bit different) once to mess around with the game, just for fun. I was wondering if this will have an effect on the legitimacy of Pokemon I catch within a new File in said cartridge. Will these Pokemon be considered hacks/not legitimate (maybe some marker within the code that determines this), or does starting a new file erase all traces of gameshark use on the cartridge? Could anyone corroborate on this?
I know it is a pointless question, but I want to start over clean and enjoy Pokemon how I used to.
