I usually don't use DOS versions either, but I found that the MAME 0.34 (so DOS) runs beautifully (and with much higher framerates than the Windows version) from a DOS prompt within Windows. So there's no need to reboot to DOS or anything; simply choose DOS Prompt from the Start menu and run it from there. I don't really see what the big deal is, but like Pat said every 0.34 version for every platform will do.(posted 9193 days ago)Ben Jos.
