Some rips of Sonic & SEGA All-Stars Racing were dumped with a 3.55 firmware requirement. If you are on a higher firmware (4.87, 4.88, 4.89, etc.), the game may execute incorrectly unless patched.
Open PARAM.SFO with a SFO editor. Change PS3_SYSTEM_VER from 04.2000 to 04.8500 . This forces the game to ignore older library checks. sonic and sega all stars racing ps3 pkg fix
