There are many great visual guides out there for installing a single switch region mod for the original Mega Drive, but in my searches to find one for the Mega Drive II (specifically a MD2 VA1 PAL in this case), I found mostly ancient guides and forum posts often missing images or including instructions on how to perform the more complex process of replacing the DFO as part of the mod. Since I use SCART for RGB anyway, I didn’t much care about dealing with replacing the DFO and wanted to perform the simplest possible mod to render my Mega Drive II region free.
In this post, I’ll detail the process with images for illustration, though I would like to preface this with a disclaimer that any modifications made based on what’s written here are performed entirely at the reader’s risk. I do not claim to be an expert and this modification may not work if the board differs from the one specifically mentioned.
