i was just reading the review and noticed that in the pro and cons section, it says that contra 4 wont boot this this card. "- 99.99% compatibility (Contra 4 fails to boot)" the game does work for the DSTT. u just got to rename the contra 4 game file to contra4.nds. thats it. i no its not a big deal but i just wanted to point it out cuz some ppl might read that and buy something else cuz that game might of been the soul reason for getting the cart. So Thats All.
