A hardware platform by Sega, uses a 16 bit 68000 processor. The edge connector on the PCB is not JAMMA compatible, an adapter is needed. There are two variants of the hardware: System 16A and System 16B, currently only System 16B boards have been tested.

XRGB-3 specific settings

The tested PCBs showed distortion on the top 26 lines in either B0 or B1 mode as shown in the following photograph:

This can be fixed by setting AFC to MANUAL and changing the default value to 3. It does fix the problem completely in B0, and almost fixes it in B1 as shown below:

An off/on cycle is needed sometimes after changing the AFC settings.

Games tested

  • Altered Beast (System 16B)
  • Golden Axe (System 16B)
