I have tried for 2 months to get PAL Twinsanity working off hdd but to no avail. I have applied patches and edited hex values but the black screen of death is all i ever get.
These are the instructions i have followed for hex editing.
Open the SLES/SCES file into hexeditor and search for the following hex value 0C 00 00 00 00 70. Should be around the same spot as in the US-version. Change the 70 to 02 and just 4 bytes from that is the 40 which is replaced with 00.
Then search for 03 AE 2D E8 60 00. You should only find 3 of those and change every one of them to 03 AE 00 00 00 00.
