PS One problem???

[BluBlu]

Why is it that a backup game Spyro2 works on a PS model 9002 and doesn't work on a PS One. They are both chipped. The PS One just gives me the screen where I can choose between cd player and memorycard.
Please help

Use the ###ne Boot CD.
You can find it at :-www.playonstation.ic24.net
You need the MODchip for the boot cd to work.
It will work trust me.
You can also use the Exploder coder CD9000 and the gameshark to boot CD's but you need the MODchip to Boot.
IT WILL NOT WORK WITHOUT THE MODCHIP.
