How to make replacement back door, the legit way.

Like seriously, guys. Why does everyone use painted MDF? Late 80's+ machines are pretty much all dual side laminated chipboard for good reasons. /rant

So for the Mega-Tech you need:

* 30mm length cam lock.
* 40x60x2mm steel connecting plates.
* 18mm black laminate chipboard, cut to 59,7x52cm.
* Authentic finger prints all over as black laminate does..
Assemble it like this:

Be in awe at the legitness:

And then push your machine back to the wall and never look at it again ;)

Starting with the (to be open sourced) Mega Drive converter!

Before I start I have to give full credit to Nipedley. This person has done an incredible amount of research back in the ~2010 era and used to have his own site that is linked to on several blog posts of the time. Anyway, he posted his magnum opus on this random forum post from 2017 and then seemingly disappeared from the face of the internet.

He went out with a bang, though. Turns out that this random Mega file of the pre covid era contained gold. It has recreated artwork, scans, manuals, info for making custom menu roms, and a complete reverse engineered pinout of the Mega-Tech cart slot with full comparison to the Mega Drive and even instructions to get an Everdrive going.

So I fired up Altium and designed a board to his spec:

I then fired it up and magic happened:

My bonus reverse engineering efforts for icons in the menu paid off too:

I then got overconfident and tried my Master System converter, but that one unfortunately needs debugging I will get to in a future update...

Incredible work. Have you considered simply…. Cutting down your mega drive shells for those pcbs that don’t have long enough fingers? It’s not like children are ever going to be banging around these things.
