Played on alttpo o2 v0.3.7, both of us on the bnes mercury performance core in retroarch. We played with small key sync off because it was causing problems before.

MOD NOTE: love to see more co-op runners! So its approved for now... im looking into the discrepancy between software versions used in this category; some alttpo/o2 versions have over 55 seconds of delay on aga1 & bat crash after aga 2.
