I have a R4i-gold (r4i-gold.eu) that I have been using one my DS lite for some time but I just bought a new 2DS 20th Pokemon Aniversary Special and I wanted to know if its possible to use the same flashcart there to play the same DS game (not 3DS ones). So far it only gives me an error message when i try to run it. Any easy help would be gladly accepted.
