Hacking FREEZEING game

[xxxkumcell]

I have an r4 card (image below) and firmware also below
anyway I got it yesterday and downloaded GTA Chinatown and sims 3 onto it for some reason during gameplay on GTA china town it freezes but the music keeps going but the screen is stuck I do not know how to fix this what should I do? (played on ds lite) I tried waiting it out but still, after a few minutes, it does nothing now what?

hmmm... i have the same model so i'll test it in a bit, that will point out if it's a hardware problem or a rom related one.
