evilo has updated his port of the multiplayer game”Super Mario War”. Release notes:

As promised, a little update to add a great feature : Multitap support thanks to the work of Drakonite on the SDL library (as well as others little fixes to the driver, but that should be however not visible). Also, I saw a lot of complains about the outdated version on which the PS2 port is based, but all I can say is : don’t discourage people, and try to enjoy this version anyway(that was initially a try for the PS2 SDL library) while waiting for a fresh new port based on the version 1.6 !
