Out of the blue comes a new version of MAME with Kaillera built in. In case you didn't know, that enables you to play arcade games supported by MAME online over the internet. I'm fairly certain this makes Mame32 Plus! Plus Kaillera (phew) the most up to date version of MAME with online play available. I'm not sure what the changes are in this particular version as it's in Japanese.
