A new version of MESS, the Multiple Emulator Super System based on MAME has been released. As usual, this version incorporates all changes which were made to the latest version of MAME and some emulation specific changes. In this case, a small bug affecting the quality of the PSG emulation has been fixed. This did not affect the accuracy or EmuRank in the MSX Emulator Comparison, however.
