Just a quick question as I don't own a slim myself. But can't ggbuild easilly be patch with a different dvd drive (keyvault)??
It won't allow you to play on live but it will allow you to play games.
As an alternative you can for now use ggbuild to transfer games with ISO2GOD to a hard drive of your slim. This way you can also play your games...
Some people owning a jtag don't even have a dvd drive. They just modded it out cause it makes to much noise :p
That's not so possible, editing the KV will give you Christmas lights in a FAT, don't know about slims, you can toss a different drive as is, I have a Falcon with 7485 in OSIG, using Sammy as normal, don't try to spoof it or it will show E66, let it be whatever it originally is.
Given 0225 drives needs more info, it could be possible that no other drive will work, only available workaround would be to permanently glitch.
