Is the Lumines game in ISO format?

Is it in the rite folder?

-Heres wat i usually do 2 start Lumines or watever ISO:
1. turn psp on. -fw1.5
2. start DevHook v.45 from the games folder.
3. switch UMD select 2 Lumines.ISO.
4. switch fw 2 2.71.
5. choose START.
6. insert a UMD disc, n let the fun begin

i dont mess w/ anything else in the DevHook menu. Hope dis Helps. if not try another ISO game.
