About This File
mame64.exe - Normal Mame with Nags removed.
mamearcade64.exe - Mame Arcade ONLY emulation. (No MESS systems).
Its recommended to download the full 0.219 official pack and install it, then just overwrite the exe with the replacment, this covers any changes the mame devs may have made to the support files.
After you have done this, make sure you copy the folders artwork, ctrlr, cheat, hlsl, ini, folders and the mame.ini file from your original mame folder, and move/copy them to the new install.
