+The file header looks like this.
+UGRF 0x01000000D7B06247871D0000 UGSF 0x00AE0C00 UGMF 0x60B00C00 UGCF 0xF8B10C0020 AMX 0x18B30C00 PROP 0x70B30C00 SIZE 0x20CF0C00
+Then its padded by a bunch of 0x30's
+And then the first song
+UGSF 0x01 12days_mbox
+I would venture to guess that:
+"URF" & "UGRF" = Ugobe Resource File
+"UGSF" = Uglobe Sound File
+"UGMF" = Uglobe Motion File
+"UGCF" = Uglobe C??? File
+</code>
+<blockquote>
+I took the first UGSF segment and pulled it in to audacity as a raw file. It didn't sound very good, but I could discern a ho ho ho. Signed 8 bit PCM worked the best for me, but like I said it didn't sound very good, so there must be something else done to the data. Perhaps it's just scaled, or there's some output filtering.
+Also, the AMX in the header probably refers to the pawn virtual machine code. One of the pleo's creators said that's what they used. I didn't find a decompiler for the AMX virtual machine, so I haven't tried to extract any code there. It is documented and the source code is available, so I imagine that might be a good place to look.
