My system originally was 3.03 then I used an upatched copy of Liberty City Stories to downgrade to 1.50. Everything seems to be fine after I use the winstaller to go up to 3.03 OE-C. However, once I try to play Libery City Stories I get to a screen that tries to load an old game and the screen goes black. I have to go into recovery mode and go back to 1.50. How can I use 3.03 OE-C and still play newer games like Libery City Stories?
