I wanted to know if there are any GBA emulators I can use on my r4. Thank you in advance for any help any of you can provide.
when in doubt you can also google search "what you want" + gbatemp
a) Lameboy does not play GBA games. Only GB And GBC.If you haven't found one already them yes there is one its called LameBoy and you put it on your r4s root folder and then put in your .gba and .gbc files on the sdcard any where. Then boot up your d's with the r4 in and run the LameBoy.nds and it will search the sdcard and show only the .gba and .gbc. Then you tap on the game you want to play.
