Okay got it. Thanks techknight !

The seller confirmed that it was an easy install. The BIG problem now is the ROMs and the CDEV.

Maybe I'm just dumb but what does this sentence mean exactly:

NOTE:  THIS SOFTWARE WILL ONLY OPERATE IN 

                        CONJUNCTION WITH THE VERSION 4.4 ROM UPGRADE 
                        FOR SYSTEM 7.0 COMPATIBILITY.  IT WILL NOT 
                        WORK WITH VERSION 4.1 ROMS OR OLDER.

Does it mean: 1/ You have to use this software with v4.4 Roms to run SSW 7 

              OR    2/ The software will only run with v4.4 Roms which were designed so it could work with SSW7 (but could run with older roms with System 6?)

I'm confused.
