This is not the fanciest portable ever, but I really like it. Mostly due to the fact that you were so meticulous with mounting the components, and the way you routed your wires.
Do you plan on changing the d-pad in the future? It might be hard to mold a traditional pad into the particle board, but perhaps you could recess an original controller flush with the case. It's been done before, and I think would look great on this portable.
Just my opinions.

Thanks for all the comments!
grahf: I like to keep my designs plain and simple not too fancy. When i do all the wiring up on electronics or portables i like to keep everything neat and tidy. Because then its easier for me to diagnose any faults, without spending ages poking around with a mess of wires. The curent buttons are fine, but swaping them for the original controller seems a good idea that i might think about doing in future. Yes i have seen it done before on c_mon's snes portable.

Yes, nice job, nicely finished. Neat.
I bought an SMS to put into my project in the next months at a car boot sale a few weeks back very cheaply (SMS, controls, power, 14 games, £10).
Interested to see a pinout for the RGB and audio if you have one please. Pinout link?
How did you work out which other components for the RF modulator were removable, out of interest?
You could mount a D-pad in there to replace the four buttons if you like, similar technique I used, however it might be too late in this project as you would need to put a thin layer of something on top to conceal the D-pad surround.

Very nice! I've got a future plan for a SMS2 portable, althought with my slackness it could be a number of years before it's started!
Edit: I found a more reliable link for the sega master system video and audio out: http://www.smspower.org/dev/docs/wiki/H ... ideoOutput also for those wondering im using the composite out, not component, that was a typo
The one i've used for my SMS2's at home (although i'm only using the Component out part) is this one: http://www.mikeg2.freeserve.co.uk/masterful/rgb.htmlbacteria wrote:Interested to see a pinout for the RGB and audio if you have one please. Pinout link?

Progress on portable SMS2 - 0%
Re: The Master Boy - Sega master system portable
Great portable. Really awesome. Where did you take 5v on the PSOne screen to enable RGB? Can you show it on a picture? I'm thinking of portablizing a SMS2 soon and need this info.I took the RGB and sync video signals directly from the output stage of the Sony CXA1145 video encoder. I did this because the chip contains its own video amp circuit. I also took a 5v line to the psone screen to switch it in to RGB mode. Sound is take from the audio out line where the RF modulator used to be.

Those pinouts do not belong to SMS 2. The system only outputs r/f signal and doesn't have s-video output. Thanks for the info, though...phantom92opera wrote:http://www.gamesx.com/avpinouts/genesisav.htm
