MAMEWorld has recently celebrated the 20th anniversary of the well known arcade emulator MAME with a dump of several arcade games. One of the games is the rare SegaSonic Cosmo Galaxy Fighter from an anonymous donator. The original game was a vertical shooter that as the name suggests stars Sonic the Hedgehog as he has to shoot down Dr. Robotnik and his robots in space. The arcade cabinet was originally a Japanese exclusive, with the monitor having an interesting “swaying” effect as you play the game. SegaSonic Cosmo Galaxy Fighter is comparable to Waku Waku Sonic Patrol Car in terms of presentation.
This dumping means that as of this point, all known Sonic arcade games have been dumped in some way or another. However, the ROM of the game is not available publicly as of this writing, meaning currently it’s not possible to play the game yourself using MAME. Still, the fact a game like SegaSonic Cosmo Galaxy Fighter and the many other games recently donated being dumped means they won’t be lost to the trials of time.
