You probably want to check to see what games you own which have already been preserved. Then download what you want.
It seem to me pointless to go through them when the hardwork has already been done?
I converted a load of my (Sinclair Spectrum) tapes (and a few I didnt own
) to low bitrate accelerated MP3's so they only take a fraction of the time to load, take up a few hundred KB and I can use a £10 MP3 player.
