XB-Monitor+ is a loader for Examu's eX-BOARD arcade machines software.
Originally developed by Romhack: xb_monitor
Some features were added/changed/removed:
The game Arcana Heart 3 might need compatibility mode enabled in newer systems in order to work.
The code has been cleaned up a lot and reorganized completely, with some parts rewritten, so should be easier to see what's going on.
