Sega Mega-Tech Restoration
- Thread starter mourix
- Start date
This is awesome! And his resulting wiki is very good stuff.
Is this the year of the Mega-Tech or something?
So.The repaired board has been running for many hours now and it is working great.I couldn't be happier with the service I got from Luke.When I opened up the box there was even a nice gesture in there as well as a working board you could eat your dinner off.
Now the cosmetic refurb begins lol

Luke has done a top job on your repair no doubt and well worth the wait. Pleased for you mate.

Yeah I agree. I'll likely go over my MegaTech and see which games I'd like. Definitely Sonic 2, Rocket Knight Adventures, Gunstar Heroes and Comix Zone. Possibly Ristar and Aladdin. I just want some quirky fun games to switch about.

The choice is wide open now and will be nice to be able to play the elusive titles which didn‘t surface when I was collecting the system.
Gunstar heroes will be a great addition 👌

Swapped the marquee bulbs (thanks to Maurix for the size) and now want to remove the operator stickers and sort out the screws.
How do I remove this from the wood without damaging the finish?
And this from the plastic?
Finally the screws?
They seem to have what I think is oxidisation?How do I clean them?I thought soaking in vinegar?
And what colour should they be?

Did the screws come out ok ? The torx head on screw looks a bit worn. Normal finish of screw is a satin black.
I think vinegar may be too corrosive , fine toothed wire brush or sand paper could be best.

That’s good they can be reused. You could either get a rust remover spray and wipe away or rub with a bit of wet and dry - push them into a piece of foam or polystyrene and spray with hammerite satin or similar.
Thank you for the info Mr Flyback.
On a slightly different note,Luke @ Retrosix wanted me to ask a question.He WILL join up but he's too busy fixing Megatech boards at the mo lol
He asks.......
I've just fixed another one, but on testing I'm not sure its fully fixed. When I play Sonic 2, and just let it start and run, after the 1 Player / 2 Player home screen it starts the demo usually after that, on this one it just fades to black, audio of the demo continues to play, but it remains black until it comes back to the menu then the second time it starts the demo its normal.
Tried with 2 copies of Sonic 2 so it isn't the ROM. Wondering if thats a known Mega Tech glitch?
Anyone???

Awesome, guys. This makes me happy. I put a list of all available games and their respective home console review scores here.
Putting more of this stuff out there is always better. Could you try to scan at the highest DPI your flatbed goes? Either 600 or 1200DPI. Thanks!
Good work!
Vinegar always works fine for me.
For this screw, I'd just finish with a thick black permanent marker as paint/sandpaper does not really play nice with security torx.
You can buy sticker remover from Amazon and other places which works nice. Plan B is heating the sticker with a heat gun but that is risky on plastic if not careful.
I only got the Sonic Classics cart but I'll let it run and report back.
I tried it. After pressing the start and waiting, it goes to this demo:
However, this demo uses some weird video mode that makes my arcade monitor really unhappy. Like it's blurry/flickery/interlaced. At first I thought it was my CRT taking a dump.. but it goes away with the next demo. You can even see a bit of the glitchy video in MAME. I think Sega is using some wild scanline interrupt trickery to allow for the dual race screen. With Luke using an LCD, it wouldn't surprise me if it just can't sync to it and shows black instead.

Sonic 2's 2 player mode uses the Megadrive's Interlace Mode 2, which allows the system to output a 320x448 image by alternating between even and odd lines every frame. This allows the game to display two full screens' worth of graphics, at the cost of effectively halving the frame rate to 30.
Quote from the webz ^ I do remember reading about this back in the day. Hope you're well
