Kinda looks like it's repeated a number of times.

0x0 - legacy
0xf400 - efi
0x20000 - legacy
0x2f400 - efi
0x40000 - legacy
0x4f400 - efi
0x60000 - legacy
0x6f400 - efi

0x20000 = 128k, so you could probably dd just the first set and use that
(dd if=GT610ROM.ROM of=GT610ROM.ROM2 bs=1k count=128).  The entire last
512k of the file is useless.
