INSTRUCTIONS FOR A CORRECT SETUP (ALSO WITH A FRESH INSTALL)
After extracted and overwrited existing files from the 32/64 bit package simply do the following steps:
- Move HISTORY.DAT, MAMEINFO.DAT, HISCORE.DAT to their new directory \DATS\
- Delete your existing GAMELIST.INI and MAMEUIFX.INI in the root directory
(This is required for the "Times Played" feature which has been re-introduced)
- Delete MAMEUIFX.CHM help file and M1.XML file in the root directory
(A new M1.XML in the \M1\ directory and the new HELP.CHM file are already provided in the package)
- Launch the emulator and (sorry for that!) wait for the first audit process to be completed. Ready.
