Need some advice and Info About slot 2

hi there people
so me and my brother and big pokemon fans and we have all the gen 3 games on original cart.. but have platinum and hg/ss on r4 so my bro traded all his gba slot 2 games to his platinum save.. then the plat save corrupted in true r4 fashion so i know you cant emulate gba games on slot 1 so how do i go about emulating gba games on a slot 2 and can i still use my r4? i really need help here i have no idea where to start with this... or what device to use any help would be greatly appreciated

I don't see how emulating games can help, since your Pokemon on the GBA are totally GONE. How did the save get corrupted? I can probably help you with that.OR, if fixing the save doesn't work, if you make a list of ALL the Pokemon you had on the GBA, with as many details as possible, I can help you pokesav.

so we can paly them through on pc speed up the gameplay then transfer the rom to a slot 2 device.. so back to my previous questions thanks for the help though..
