The Pro CDX was released to circumvent the region lock in the Mega-CD hardware.  Whilst sprite-based games generally ran well, the NTSC to PAL conversion caused synchronisation issues with FMV based games, making the fast-paced ones unplayable.  On top of that, some games refused to work at all.  Some of these problems, along with issues with the Mega-CD 2 and MultiMega hardware, were resolved with the Pro CDX 2 cartridge.

Of one use for one of these was to play The Lawnmower Man.
