+Unfortunately, little information is currently present for other variants. If you have any, please add this information!
+Later revisions of the Genesis/Megadrive merged the three chip setup into two chips. This makes sense from a cost point of view, but we do not currently have any pinout information for these chips.
+Images seen suggest that there may have been a version where the VDP, Bus Arbiter and the I/O chip were merged into a single ASIC.
