. This is a minor bugfix release (I did add two more Seibu shmups courtesy of Ville Linde) and contrary to the scary warning Bridge 0.5.5 gives you it does work with this version, although I imagine Fujix will have a new version as soon as he can.
Extended note: the SPI games won't audit properly in Bridge 0.5.5. Basically Bridge and any other utilities working with M1 need to treat a CRC of 0 as "ignore the CRC, just check the name".
PPS: mameworld.info's a bit unstable lately (I really don't think it's the mass of people downloading M1 even though I'd like to) so try again later if you can't get through.
