Custom Sega Mega-tech cartridges project
My latest Dream-come-true is this project of filling the 8 Megatech cart slots with my favourite games!

Sega Mega Tech recreation
Hey! This is the final piece of "Sonic" hardware that I was chasing after! I bought this board from www.arcadehry.cz and started to build the cabinet and wiring from scratch!
I have two working monitors already in place now waiting for some stickers/decals to make it more original :) After that, the controlls will be made.
Inserting some extra info:
Found out pinout of CN2 connector:
1 - P1 Up
2 - P1 Down
3 - P1 Left
4 - P1 Right
5 - VCC
6 - ?
7 - ?
8 - ?
9 - P1 Button A+Start (Sonic jumps and game stops at the same time)
10 - ?
11 - ?
12 - ?
13 - P2 Up
14 - P2 Down
15 - P2 Left
16 - P2 Right
17 - VCC
18 - ?
19 - ?
20 - ?
21 - P2 Button A+Start
P1, P2 and CN2 controls go through NEC2501 to galvanicaly separate them.
GUN connector controlls don't go through 2501 only through simple 3 pin filters.
