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. As for MSX emulation, regressions caused by Z80 port changes were fixed and the code to mode 2 support of the 8255 PPI was rewritten. We will soon update the MSX Emulator Comparison and will inform you if these changes also affect its Emurank.
