====== OVLN ======

This is a format for compressing game code and other misc data in the ROM. There are 4 OVLN blocks in Supercross 2000.

This format uses [[supercross_2000:eahd|EAHD]] for the compression, which starts at offset 0x10 of the OVLN block.

----
===== Header =====

The OVLN header takes up the first 0x10 bytes of the compressed file. After the header is a EAHD compressed block.

^Offset^#Bytes^Description^
|0x00|4|"OVLN"|
|0x04|4|Compressed size (including the header)|
|0x08|4|RAM location to decompress|
