Hey, HazelSX2,
I have the same Idea. A few weeks ago I bought a bally Wulllf Multigame2. The AmaPCI Card Battery is empty so the machine is no longer usable
My next idea is to built a MFME Machine. The Pentium 3 and all the other components incl. The elo Touchscreen inside the cabinet works fine.
I have installed a fresh xp on the pc.
Next steps are:
Mfme frontend
Kodi
Pac drive, ipac2 or arduinos
Regards Andy
