After owning a flash cart slot-1 for DS, thoughts have arisen to purchasing a slot-2 flash cart...but now I'm a bit skeptical. I know for sure that purchasing a slot-2 will enable me to play GBA games on my DS--but I already have a hacked PSP with a perfect GBA emulator. BUT, other questions arise with the GBA Flash. If I were to purchase a slot-2 for my Ds, would it work in my GBA SP's as well? Would it be able to link and trade and all that for games like Pokemon? And in the DS, would there be any possible way for it to detect a certain game in DS Mode, to use for games like Pokemon P/P/Pt for Pal Park? Or should I forget it altogether and just stick to my PSP?
