Looks like the proposed EU Kids Act is far worse than we even feared it would be. Every online game to require strict age verification, private game servers to be made illegal. Effectively it would spell the end of the "stop killing games" initiative www.youtube.com/watch?v=mQRc...

I hope your Sega Master System is ready. PicoPak is coming. #MasterSystem In this first look video, I talk about my save state implementation. Lots more later on as there is a hell of a lot to cover. This is just the tip of the iceberg. RETROFROG DOES.

You're welcome! 👍

It is, it's beautiful. If you use a TwinDiamond on the port at the side, I'm pretty sure you can stick a receiver in there for an 8bitdo controller for the NES or SNES.

More pics of building it up to it's final form. As well as a picture of a bodge I had to make because I singed a very tiny and necessary pad, for audio.

Here are some pics of me building up the NESRGB kit.

A long time ago, I recapped and RGB modded this Twin Famicom. For completeness sake, I'm adding some pics of the process in a new thread, so that I can import it to my blog. This is the console post-recap. Look at that belt! Completely hardened and broken.

Yeah, that's definitely a good way to get a fix of some pleasant driving.

André Coelho @hitmanmcc.com · 30/09/2026
I'm intrigued. Seems like something that could be useful for some rest and relaxation.

Tuesday, time for a new video! Super Castlevania IV, for the SNES, has a lot of slowdown. My FastROM patch takes almost all of it away. Full comparison video: www.youtube.com/watch?v=P4s6... Patch: github.com/VitorVilela7...

That's cool. It's hard to come by one of these systems for a not insane price these days. In my own units I did not require a replacement. For this one I restored for an acquaintance, they sourced a NOS one from a Spanish shop, it cost him 99€ for the part.

André Coelho @hitmanmcc.com · 29/09/2026
Yeah, a recap usually doesn't save a Mega-CD system from that but good luck to you my friend. Hopefully it's something easy to fix or replace, as the lasers for these are quite expensive.

Also re-did the first one.

André Coelho @hitmanmcc.com · 29/09/2026
And here's the second pak. @misirajeduart.bsky.social was complaining so I opened up that one too in order to show that 0603 can work with a steady hand.
240
André Coelho @hitmanmcc.com · 29/09/2026
Thanks! 0603 is bordering on tiny but the lowest I've gone is 0402. I don't have a microscope so I think that's probably about the limit of what I can solder with just my eyeballs. I think in this case an 0805 would have been a better fit, it could have bridged the pin gap appropriately for the job.

André Coelho @hitmanmcc.com · 29/09/2026
Finally circled back to fix something here. As per @nosIndulgences' research (x.com/nosIndulgenc...), this is the proper way to do this mod, in order to avoid data corruption in the long haul. Sadly, I couldn't make this as neat as I wanted to, my 10K resistors are too small.

Hahahaha, you're welcome. 😂

Much harder. It's a mess of overly complicated interconnected boards, screw on to the top of the shell. They couldn't have possibly made it worse for repairability. Lots of cables with hard to remove connectors and not much wiggle room.
110
André Coelho @hitmanmcc.com · 28/09/2026
Yeah, it was. Thank you. This console is so beautiful but such a pain to work on...
110
André Coelho @hitmanmcc.com · 28/09/2026
Yeah, normally CIB is so much more expensive.
010
André Coelho @hitmanmcc.com · 28/09/2026
It has a few dings but it's not bad at all.
110
André Coelho @hitmanmcc.com · 28/09/2026
Then the finishing touch, applying some UV protectant to the shell, packing it up, ready for its new home. What a journey that was!

André Coelho @hitmanmcc.com · 28/09/2026
A final test, with some CDs, backups and originals.
130
André Coelho @hitmanmcc.com · 28/09/2026
So then, I have to strip everything down again and recap that too. 😩
110
André Coelho @hitmanmcc.com · 28/09/2026
Disconnected everything, remove the old laser, put in the new one and voilà. It works!
120
André Coelho @hitmanmcc.com · 28/09/2026
The owner eventually supplied a NOS laser, so off to the races we went again.

André Coelho @hitmanmcc.com · 28/09/2026
Here's a video of the spindle working.
120
André Coelho @hitmanmcc.com · 28/09/2026
Then I tested the motor for the spindle too and it was fine. So... laser it was... as I feared
120
André Coelho @hitmanmcc.com · 28/09/2026
Now all that was left to do, was figure out the CD-ROM situation... 🙄 I tried various things, measuring various components on the boards, cleaning ribbons, switches and the lot. Ultimately, I ended up completely swapping chassis and proving every board faultless.

André Coelho @hitmanmcc.com · 28/09/2026
And here is said F-RAM installation.
120
André Coelho @hitmanmcc.com · 28/09/2026
At some point I did replace the supercapacitor too. This was later superseded by an F-RAM chip installation.
130
André Coelho @hitmanmcc.com · 28/09/2026
Just look at that, how pretty, no visible jailbars. ☺️
120
André Coelho @hitmanmcc.com · 28/09/2026
Now we admire the results. First pic is from BVM, the rest is from the TINK, all using Jeff Chen's NTSC Saturn to VGA dongle.

André Coelho @hitmanmcc.com · 28/09/2026
Then you route the ribbon cable as shown in the pics, underneath the plastic structure that holds the motor and gears for the CD-ROM's motorized lid. Make sure the V-shaped cut on the black portion of the ribbon faces the back side of the console, when inserting into the DIN QSB.
120
André Coelho @hitmanmcc.com · 28/09/2026
Then you wire-up composite, left and right audio and, power to the QSB that houses the new DIN.
120
André Coelho @hitmanmcc.com · 28/09/2026
After that, you remove the OEM bodge-wire and S-video ports, to make way for the new Saturn-style DIN.
120
André Coelho @hitmanmcc.com · 28/09/2026
The kit comes with a QSB that solders on to the Sony CXA1145M encoder. This is what taps into the RGB signals.
110
André Coelho @hitmanmcc.com · 28/09/2026
How do we fix this, you say? Well, it's easy, you install an RGB kit from Oleg Endo.
110
André Coelho @hitmanmcc.com · 28/09/2026
In the meantime, we take a detour to handle this. I don't know if it will make it past the compression algorithm but this thing has vertical jailbars (composite and S-video) on the native outputs. First 2 pics are from my BVM, the other 2 are from a RetroTINK 5X Pro.
120
André Coelho @hitmanmcc.com · 28/09/2026
So, does it work, well... yeah, partially as I expected, still nothing from the CD side. Streets of Rage 2 and Earthion were kicking ass though.
120
André Coelho @hitmanmcc.com · 28/09/2026
Now it was fully recapped, it was the moment of truth... FYI, there's 70 caps worth of work in these bowls.
120
André Coelho @hitmanmcc.com · 28/09/2026
Here we can see a fully recapped CD-ROM board and laser, so we're close to the finish line, maybe, lol.
120
André Coelho @hitmanmcc.com · 28/09/2026
Next up, we move to the left side (CD-side) of the console to apply the same treatment. White vinegar and isopropyl baths and busting out the Deoxit, for the pots for the karaoke effects and microphone jacks. Also fully recapped the audio control board.
120
André Coelho @hitmanmcc.com · 28/09/2026
At this stage, I ran quick validation test. Just to see if everything was as expected.
120
André Coelho @hitmanmcc.com · 28/09/2026
Afterwards, I proceeded to treat the problem areas with flux and new solder. Refurbishing and covering up some dodgy looking vias and surface components, as well as all the regulators, which usually get attacked too. After cleaning, both boards from the right side got a recap.
120
André Coelho @hitmanmcc.com · 28/09/2026
With that out of the way, I proceeded with the removal of the old electrolytics and treating the boards with white vinegar, followed by an isopropyl rinse. There were a lot of capacitors giving off a fishy smell on removal.
120
André Coelho @hitmanmcc.com · 28/09/2026
Inspecting the underside, I managed to find our missing capacitor's location, right next to the DC input jack. My assumption is this thing took a hard knock. As you can see, there's some adhesive beneath the SMD components.
110
André Coelho @hitmanmcc.com · 28/09/2026
I proceeded with disassembly and inspection and found some problem areas on the board that would need treating.
130
André Coelho @hitmanmcc.com · 28/09/2026
I powered it on and it worked but only with cartridges. It would refuse to read any CDs. Maybe it would be a simple fix but my experience with Mega-CD systems was telling me otherwise. I haven't personally seen one cured of this with a recap, so I was assuming dead laser.
