Gaming Problems for 2 games

[bb521]

I have problems for these two games, GTA:china town wars, and the newest final fantasy 3D game (forgot name)
the problem with GTA is, right after I click one of the two profiles in the beginning of the game, my DS screen goes black, and doesn't do anything.
the problem with the newest Final fantasy game is that I can't save, when I go to one of the saving stones, it says unable to save, reinsert the DS card.
I have a DSTT (forgot which version)

These games have anti-piracy measures put in place to prevent them from working on flash cards. Use cheats to bypass them.

Also, I suggest getting a better flash cart.

well, the most recent cheats doesn't have the bypass anti-piracy

Ummm, yes they do. For GTA, it's under Misc. Cheats, for FFCC: EoT, it's in the main menu, as, "Anti Piracy Bypass Code."
