wood r4 for clones problem

on all the roms it says the data of the game is corrupted

Yep.Gotta use your firmware.Most of the ports are crap and never get updated anyways.http://www.linfoxdomain.com/nintendo/ds/

its probably because your using wood r4 for r4 originals, on a clone, which the saving doesnt work, what cart do you have, and what wood r4 are you using, just use ysmenu if your cart is a clone, has better compatibility than woodr4 for clones,
