Ok for anyone who thinks it is not possible to play backups on an unaltered PSX I have news it is possible and I have become quite good at it so I thought I would make a guide on it as there are so many psx ISO's that do not play at full speed besides playing the games on PSX is a much better experience lets start off with the basics...
What you will need...
Step 1: What You Nedd To Burn Psx Backups
1)A PSX Console (unmodded) you wont need this guide if it is unless you are just wondering about how to burn your iso's to play on the console
2)Alcohol 120% (or Damon tools) will explain later
4)a paper clip (can substitute for something else) will go into that later as well
5)an actual psx game (any game should do) but must be an original copy in order to make this work
