CAN SOMEONE HELP ????????

1. Use proper English. Do not abbreviate your words as if you're text messaging someone.
2. Post your flash cart issue in the proper section : http://forum.romulation.net/index.php?board=104.0
3. Post as much detail information as possible. There are over 2 dozen carts going by the name R4.

Maybe your R4 card doesn't support that game I once had that problem try searching on Google "R4 Upgrade"
Good Luck!
