ps1 game modified for psp back to .iso?

is it possible to change a ps1 game modified to run on psp, back to original iso file?? reason being i have version of x-com for psp, however i wish to play it on xbox, i already have dosbox version, but i want it for pcsxbox, i heard that it plays very well... any help would be appreciated

with the popstation gui PSX2PSP, it allows you to reformat a psx eboot into an ISO.

this should be in the help section
