You need the magic key 2 tools in order to make the ps2 think the drive is closed all the time, basically so that the disc will spin with the drive open.

Once you've got these in place (Only have to do once and piss easy to put in, no breaking of any parts and no breaking of the warrenty sticker) simply put in the swap magic disc, let it load, take out the swap magic and put the backup in. Press any button and thats it.

There are a very small amount of games that don't work with swap magic 3.6 and for the ones that don't easy workarounds are available.

If you're looking for an easier life with a pretty much guarenteed 100% success rate you'l be better off with a modchip.
