Here's the breakdown:
PS3 models that support PS1 discs:
* Original PS3 (Fat) models (CECHA, CECHB) These models can play PS1 discs.
* Slim PS3 models (CECHC, CECHD, CECH-2000, CECH-3000) These models can also play PS1 discs.
* Super Slim PS3 models (CECH-4000, CECH-4200, CECH-4300) These models can play PS1 discs through the PlayStation Network, but not directly from a disc. You need to buy the PS1 games digitally.
PS3 models that do NOT support PS1 discs:
* PS3 models without the backwards compatibility feature. You can check if your PS3 model supports backwards compatibility by looking at the model number (listed above).
Things to keep in mind:
* Not all PS1 discs are compatible. Some PS1 games may not work properly or at all on the PS3.
* PS1 games on PS3 may run slower than on the original PS1.
* You can use a PS1 emulator on your PS3 to play most PS1 games. This requires a jailbroken PS3, so it may not be a suitable solution for everyone.
The best way to play PS1 games on PS3:
1. Check if your PS3 model supports backwards compatibility.
2. If it does, try playing a PS1 disc.
3. If it doesn't, you can buy PS1 games digitally on the PlayStation Store.
4. Consider using a PS1 emulator on a jailbroken PS3.
