how is it possible that Midnight Club: Street Racing is unplayable as iso?

[Rafaelrios]

The game is an official ps2 classic and is unplayable as ISO according to the ps2 compatibility list,how is this possible?

I Don't understand much about Emulation,but aren't the jailbreak and official ps2 classic the same emulation.

Not quite the same. There are "Emulator Configuration Files" used by Sony when playing with their Official ones from their Store. Finding the correct settings is key!

Also a bad dump from your original Disk can also show issues etc.
