I am looking to backup my Heart Gold save from my CycloDS and transferring it to a retail cartridge with NDS Adapter Plus (with a little Pokesav editing). But I'm not sure how trainer IDs, Secret IDs, and so on, work. For instance, if IDs are rom specific, I would rather keep the IDs from the retail cartridge. So, my question is: How do IDs work? Are they cartridge specific? If so, what all do I need to edit of my rom save before I transfer it to the retail cartridge. For instance, I was thinking (if necessary) of changing my IDs to match that of the retail cartridge (but that would mean having to change the IDs for all my pokemon as well). Could somebody list what I would need to change in my rom save to make it seem like I played the whole game on the retail cartridge? Any help is appreciated.
