Just a small Blog following some of my endeavours in the world of retro repairs and modding. Also a way to record my hobby without being the full on Youtube wannabe! Maybe someone will read it and be motivated to fix something themselves!

SEGA Game Gear - Pimped!
As you can see above, it looked well for its age. A few screws later and I got the thing apart. Looking at the board I noted the black square capacitor bodies dotted around, that was my first job, simple remove and replace. So I thought!
I taped some bubble wrap to protect the old screen, who knows may be a spare for future. I heated the iron up and used flux gel via a syringe to help remove the caps. The smell was terrible, fishy and toxic all at once. The plastic bodies of the caps were welded like small coffins to the board, leaking inners had cemented these making the job messy to say the least.
This was beginning to look like a car crash, possible pads lifting when trying to remove welded legs. I just took my time and worked with what I had. I decided to just focus these pics on the worst section as the rest of the capacitors were pretty much the same scenario throughout the board. Not my best work by any means, functional was all i wanted before redressing the terrible joints.
Some bodies came off whole, most coffins collapsed and fermented their wonderful odour, solder sucker, solder wick and too long a time to record and I got them all replaced.
Yeah I know what your thinking, looks just as bad if not worse. Good soaking in 99% isopropyl alcohol should get rid of the flux sheen and improve its aroma. At this point I had faith in my joints at least. Above shows the caps i had to replace on my version board ( 2 chip version) as you can see two hefty IC chips on the bottom right. Next I had to remove a few components not needed as well as the current backlight and screen modules.
I cleaned and prepped the edge connector as it had lots of connections I had flooded with solder to remove the large ribbon. Although the new LCD screen only uses 2 connections, pin 9 and pin 20 from the control board.
No shorts across pins so time to install the new LCD screen with the help of the custom printed mounts to hold it in place perfectly. The guide from Retrosix makes it easy to follow, lists all components to remove and how to place the parts before screwing together.
The control board came with easy solder templates that made for a tidy job, again the guide from Retrosix showed all connections, some fiddly enough due to tiny size.
An example of some of the small connections on caps at the bottom right. Final connection was done to connect the control board to the edge connector.
All soldering done and rest of the guide followed, cutting a supply cable and making it safe, removing the red LED and replacement with blue. Thorough clean before refitting to the housing. The new power board was a simple swap as a module, couple of screws really.
No AC adapter needed, modern USB-C with modern components. Sadly I didn`t get the Retro-Kai sound board to fit as it`s in the post apparently. Again its a simple standalone module to screw in on the bottom right of this case. I did recap the old sound board to test it anyway.
Time to put it back together, connect all the wiring and fit all the screws. Its hard to explain the difference without having the old screen side by side.
Here`s a look at the end result. The console once recapped is stable enough and looks fantastic. Its not a simple mod if your consoles had all the old caps leak like this one, there`s plenty to go wrong however as always, fortune favours the brave!
I`m also waiting on an Everdrive type cartridge, menu driven that has an sd card slot as game carts are not only hard to find but over priced in my book, damned Retro scalpers! Till next time.... OUT

Dreamcast Modification GDEMU
I have to admit to owning 2 Dreamcast consoles, not through choice but as payment years ago for sorting out a very sick PC. I was never a fan of Sega, Sonic and such. I was strictly PC at this point of time, 1998 to be precise. The Saturn was a flop in my book ,so the Dreamcast was something I chose to ignore until it was landed on me.
The Gamepad really annoyed me, as awkward as the Nintendo 64 behemoth, maybe Microsoft liked it as they made a similar beast called "The Duke". Reluctantly I gave it a go and was pleasantly surprised. The games were better than great, Shenmue II, Jetset Radio, Power Stone, Ikaruga, Crazy Taxi..... ports from Sega Naomi Arcades. Graphically alot of games looked more like PC games than jagged console affairs, PowerVR seemed to feature a lot on titles load screens. I remembered PowerVR from the PC days of Voodoo Graphic cards
