 +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.
