LiraNuna has just released v1.2.1 of his WonderSwan emulator dualSwan. According to him this will be the final release of this emulator.

This version of dualSwan comes with added support for M3SD and SCSD. Although these features are untested LiraNuna says, "it should work, as chishm’s FAT library does." Try it out for yourself. There are some good games released for the WonderSwan and the WonderSwan Color, including the first installment of Front Mission, a series of Super Robot Taisen games, and Guilty Gear Petit.

The change log is as follows:

• Fixed window mode 0×20
• Added support for M3SD and SCSD
• Source: Moved menu handlers to menu.c/h
