I have an action replay, and I'm wondering if you could use it with an R4. I know i could just put the cheats on the R4, I'd like to use my action replay since i spent 20 bucks on it Thanks
The way flash carts are set up, I highly doubt there is a way to use an Action Replay with them. That is probably the exact reason why they have been made to work with a cheat file.
Using an R4, download the cheat file from http://cheats.gbatemp.net Click "TEMP" and download the USRCHEAT.DAT and extract it. Transfer the USRCHEAT.DAT to the cheat folder.
the cheat file for R4's are basically action replay codes, so you dont really need an action replay with flashcarts
