I copied the files to my internal drive and it worked just fine, but I may try doing the archive file trick if I need the room. I didn't adjust the number at the top after I removed the line for the 9GB file so that maybe why it didn't load for me.
Finally got mine working. I'm not sure what was wrong before. Maybe a corrupt file from ftp transfer. I deleted the game from the ps3 and this time added it onto my external drive first with split4G. I then used multiman to copy the game to my internal, which multiman joined the split 9gb file back. In order for it to boot I did have to have a disc in the drive.
I would like to have an EBOOT without the little custom intro though.
Just my experience with GOWA (3.55 Kmeaw, 4.31 SEN spoof). I tried creating 0 bytes files for the 2 big psarc and those language psarc, but just that was not enough. Still need to delete those lines in the ARCHIVES and LOCALIZED_ARCHIVES in order to make it work. Hated the duplex screen but I could care less as long as the game is working. Now working fine in external!
