"world cup 90" rom trouble
« on: February 17, 2016, 03:02:53 AM »
Hello,
i downloaded WORLD CUP 90 rom (a football rom) but there is something strange in my roms (they are good roms, not corrupted) because there some clones of this rom and some do not work althought i downloaded all clones roms too.
I think it is because of this:
THIS CLONE USES BOARD-ROMS FROM YM2608
infact inside all my roms there is no YM2608 file and this file is not a bios file either.
Instead other rom clones works perfectly.

That's it:


And this is clones roms error because of YM2608 missing file:

Hi pierini1,

You need the following Bios ROM ym2608.zip :

Code: [Select]
<game isbios="yes" name="ym2608">
<description>YM2608 Internal ROM [Internal ROM only]</description>
<year>1989</year>
<manufacturer>Yamaha</manufacturer>
<rom name="ym2608_adpcm_rom.bin" size="8192" crc="23c9e0d8"/>
</game>

This bios is requested for wc90, sformula, tail2nos, etc... as they use board-ROMs from YM2608.
Bootleg wc90 clones don't use board-ROMs from ym2608.

Best regards,
JacKc.
