Hi I recently downloaded some iso's and I read around,

Recently I found out you can compress iso using umdgen which I have already done, but then I was wondering if I can use iso compressor on level 9 compression to a cso.

If this is possible will I lose quality, music and vido on the game.

some games work fine when compressed others like gta or daxter will lag if you compressed them ,with midnight club and godfather i had problems with the sound no voices or music,you just have to try it and see
using umdgen or iso compressor i think will be the same

to make my isos smaller i always rebuild the iso with ExPERT_v105

then open the iso with umdgen and inside the
PSP_GAME \SYSDIR folder delete the UPDATE folder and the BOOT.BIN file
then save as iso or cso (compressed iso)


or you can use a ripkit
