[blademaster]

how do i do this?
i have 2 games i want to back up
Medievil II NTSC U/C
Spyro 3 NTSC U/C

i am using CDRWIN 3.8D and/or CloneCD 3.2.1.1

it takes me 19 hours to make an image of a disk.
i am doing it by the tutorials placed on www.megagames.com
i have a _NEC NR-7700A (CD-ROM)
an LITEON DVD-ROM LTD163 (DVD-ROM)
and an SONY CD-RW CRX0811

do i need to patch these games after i make an image?

why does it take so long to make an image?
