WTF is with my xbox after softmodding? (Games problems)

after i softmodded my xbox only the old games will run on my xbox like HALO 1 but things like HALO 2, starwars battlefront 2, etc won't run. it freezes right at the title. what's the problem???

 

If everything worked befor the mod, Remove the mod, try your games if they work then redo the mod.

 

k. well i forgot to add that i upgraded my hd. I used hdm 1.9 on a first disk with unleash x and then something screwed up so i installed evo x on my drive and then made another disk and then that's when it stopped making games. by now i figured how to hotswap lol so i just made a new hd from scratch with my original disk (unleashX) and now it works lol.
Problem solved this thread can be closed
