I tried to use the Aluigi BMS script in the PSX2SHIP.UMD file but I did not succeed in extracting the files. The game uses Unreal engine 2 and with the other files .UMD the extraction is carried out successfully... The PSX2SHIP.UMD file contains .INT, .ITT, .EST text files between files that refer to others...
Because that file is clearly corrupt. Every 0x0a byte (line-feed) is replaced with 0x0d 0x0a (carriage-return line-feed) which means you downloaded it from some FTP using ASCII mode instead of binary. I bet I won something
