F1 Dream Bootleg
This archive contains the roms dumped from the top PCB of
my F1 Dream bootleg.

According to ROMCMP, it uses the 2 program roms from the original set *AND* 
2 of the program roms from the existing bootleg.
Some of these roms (f1-4.bin and f1-2.bin) appear to be only half the size 
they should be, but thats not the case. I double checked and they are dumped
correctly and the file sizes are correct also.

ROMCMP output...

f1-1.bin                10d_01.bin              IDENTICAL
f1-6.bin                12k_04.bin              IDENTICAL
f1-3.bin                f1d_04.bin              99.965%
f1-5.bin                f1d_05.bin              99.953%
f1-4.bin                06k_03.bin   [2/2]      99.370%
f1-2.bin                06j_02.bin   [2/2]      99.350%

Also, this bootleg PCB is fully working, but only has 1 YM2203 chip.
