I wonder what to do with split cso. I had downloaded megaman_maverick_hunter_x.cso.0 and megaman_maverick_hunter_x.cso.1 files. Both a split cso files. I tried to combine with advanced file joiner but with no luck the cso file didn't run on PSP. Also try booting with fast loader 0.7, the file seem not working in ISOSPLIT mode. So, what exactly I can do with this thing to work?

check out this link dude, i'm sure it's gonna help.
