so do you suggest to mirror twice the 1048576 roms and four times the 524288 roms?

EDIT: ok, you were indeed suggesting that. but then it would be better to simply edit the xml list to use ROM_RELOAD like in MAME wink

I will do it tomorrow if you don't beat me to it

EDIT2: exact code
<rom name="aaa.bin" size="1048576" crc="xxxxxxxx" sha1="xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx" offset="000000" />
<rom size="1048576" offset="100000" loadflag="reload" />
