My SEGA Master System RetroPie build (in progress - almost done)

After almost 2 years of planing, I've finally started working on my SEGA Master System Retropie machine.
The SMS was huge here in Brazil, and the console that I keep a lot of memories is the brazilian Master System II by Tec-Toy (that differently from US and European models, uses the same case as the SMS1).
The brSMS2 came with only 1 controller and included Alex Kidd in Miracle World in BIOS. Mine was a 'special release' bundled with California Games. Like this one:

- SEGA Master System 2 (Brazil) case
- Retropie 3 model B+
- Mausberry shutdown circuit
- cable extensions (USB, Ethernet, HDMI, etc)
- RS Power Suply
- switches, push buttons, wires, soldering iron, etc
- cleaning products
- precision files
- 6 beers
the case, already clean and shinny
Raspberry Pi 3 Model B+ and etc
cable extensions, good quality
The case was in good shape, but it was dusty and had some scratches. First I've used a multi-surface cleaning product to remove the dust. After that I've polished it with a Scotch Bright Easy Eraser (it's like a very thin sandpaper). A coat of WD40 brought the plastic back to life.
So, if someone is worried about polishing a console with these 'easy erasers' or 'magic erasers', go for it because it works great! (for safety, test it on the inside first).
2- Assembling the connectors
I didn't want to cut the cover of the case, and I wanted to have easy access to the inside when needed, so I've worked on the base only, I've removed some pins used to fix the old board and Lego (actually, some old MegaBlocks in bad shape) and superglue to make the supports for the new connections. I think that made the work easier because you can test if everything is fixed in the right place before adding super glue.
The hardest part was finding the right spot to fit everything nicely inside the console, then I've added the RPi and the Mausberry shutdown circuit, made the connections for the power switch, reset button and LED.
I've replaced the micro USB jack with a DC jack, because I think it's more resistant.
Added the Mausberry shutdown circuit, a power switch and a push button for reset and a LED.
BEWARE: I'm a noob with soldering, electronics, etc... so I'm sorry for the GORE you guys are about to see now. You've been warned!
everything fits now
It's not so dirty as it appears in the photos.
what a mess
Installed Retropie 4.4 with some games, installed some controllers, I've put the TRONKYFRAN theme with some modifications.
I've installed the awesome Joystick Selection by Meleu, so I can play some systems with the proper controller.
I've also made some custom loading screens like the SEGA Master System boot.
5- Next steps
- add a function to the 'pause' button aswell (maybe 'quit emulator' or 'Retroarch's RGUI Menu' or 'pause'), I'll need help/advice with that! I'll need to connect it directly to the GPIO and install some commands? I don't know yet how it works...
- maybe add 2 extra buttons somewhere (on the side, so I'll not break the design) with more functions.
- install a on/off switch for the fan (cooling), on the back side (next to Ethernet conection)
- some finishing on the back, add some stickers with 'HDMI', 'Ethernet', etc...
- make the high-brightness LED opaque, it's a little too bright
- ad a A/V Jack extension
- add a SD card extension, making the SD card accessible on the cartridge lid or on the extension lid (on the back)
- add a cartridge on the slot, with a custom 'Retropie' label :3
- buy a couple of 8bitdo's M30s
- build a controller mode with a 8bitdo Zero inside a broken SEGA Master System controller
- make a box for it
- take better photos (those photos suck!)
I'm very happy with it! (sorry for horrible english)
What do you guys think?

@y-ello love this! I’m a big fan of the Master System (had one as a kid as well). Great build!

Nice, I like it.
Is the extra plastic case inside the master system case needed? Does it boot straight into the splash screen so you don't get the raspberries beforehand?
