====== Anvil NTSC/PAL Region Mod ======

It is possible to change the region of an Anvil 3DO system by changing only two components. Which components need to be changed depends on model of 3DO.

====== FZ-10 ======

Currently undocumented

====== GDO-202 ======

Currently Undocumented

====== GDO-203 Alive II ======

Change X101 and add or remove a resistor at R10P. It is currently unknown if populating R10P works correctly. R10P connects VRAM S7 and ground.

A known functional PAL mod used a 47k? resistor placed between VRAM S60 (VRAM S6 after a 47 ohm resistor) and ground. The mod was not confirmed to be free of visual glitches.

The diagram on the silkscreen (located next to the access light) reads as follows:

^ ^X101^R10P|
^NTSC|49.09MHz Half Can|X|
^PAL|50.00MHz Half Can|O|
