Playing .cso files

Okay so I've read the tutorial on installing a CFW without a second PSP (http://www.pspbrew.com/forum/viewtopic.php?t=11076) and after reading it, I believe I should be able to get it to work out I have a PSP Slim FW 3.80 but I'll only be able to put the .cso games on a 1GB MS. Is this true or do I need something else?

yeah 1 gig and up. Its just a spatial issue.

Alright cool thanks, one last question kinda on the same subject kinda not, in the same tutorial it said to use a 256mg to a 1gb for the magic mem stick, Does that mean once I install the CFW I can get rid of the magic mem stick and swtich to a 4GB reg MS or will I need to format the 4GB MS to a magic mem stick?

No you don't need to format the 4 gig, but you do need the 1 gig to be an MSPRO and formatted.

alright cool, just picked up a 1gb to format and my bat comes in thurs or fri. hope all goes well
