Old Playstation Backups wont play on ps1

[guyver03]

Hi all,

I'm puzzled, i have some old playstation backups that i cannot get them to play on my ps1. The ps1 is chipped. I can play new backups on them but not the old one. I tried the patches they don't work. I've tried searching the net but i can't find an answer. It's weird because i get the psx logo but just locks there won't go beyond that. Has anyone ever run into this. Again these are my old playstation backups. Thnx in advance.
