Which flashcart do you have? Never mind, I looked though your posts and you have some Datel cart. It won't run commercial GBA games. You'll need a real flashcart if you want to play commercial GBA or DS games.
The DSTT won't let you play GBA games either as it's a slot-1 device. Only slot-2 devices with extra RAM (or NOR flash) can play GBA games. Once your DSTT comes in, consider the EZ-V 3in1 expansion pack if you want to play GBA games.
