Good SNES & NES emulators & Flash Linker for the GBA?
 

What are some good SNES & NES emulators for the GBA? I've seen a few floating around now and again but never paid much attention to them. I'm a noob when it comes to the GBA scene, I just finally broke down and bought one. :D

I'm plan on getting a flash link here in a bit mostly for the about mention above. Since I've never considered getting a GBA until now I've found myself lost out of the loop of the subject, and was also wondering what you guys suggest I get for the Flash Linker. I was considering the X-ROM 512Mb, but want to hear some options beforehand, perferbally around the same size but I'm open to anything really.

Any help would be appreicated, Thanks
