Unable to Get Backups to Work

Advice required: New to backing up PSX1 games, Reading using Blindwrite, then patching .cue & iso

Then buring using CDRwin, these go okay but will not play on a chipped playstation.

Is there anyone out there who can provide a 'idiots' guide to this whole activity - as I now have 3 coffemats & don't want to waste anymore.
