Modding my Megadrive

Nothing impresses sexy women more than being able to explain in precise detail how you can physically modify a PAL Megadrive motherboard, via only six wires and a couple of double throw pole switches (and trust me, girls LOVE double throw poles!) to clock that 16-bit beast in at the optimal 60 hertz (which is 17.5% faster than the default 50 hertz) when run through an RGB SCART cable on a compatible television, while also being able to flick between the English and Japanese language options. Because sometimes you just want indulge in the old BARE KNUCKLE technique, am I right?

Oh, wait, I was lying. The nerdy pursuit of altering electronic circuit boards is probably the least attractive thing a guy can do – but who cares when you have such pixel perfect beauty on your CRT TVs. In truth, retro console modding is a dying art, especially since retro consoles look hideous on modern TVs, and this MD represent my last venture.

I’ve been away from both the blog and the Games of the World section on the main website for what seems like weeks if not months, mainly because I’m trying to sell off as much of my collection as possible and get things in order for... a cataclysmic life changing decision next year. Well, I’m moving house at least, and I want my entire life to fit into 3 boxes maximum. HG101 overlord DA recently moved, and anyone with a big collection will confirm, it’s not easy.

The MD came with a Sega CD unit, and to increase sales value I decided to mod it. Although the Sega CD unit can only play PAL games, you can rip NTSC games, patch them, reburn them onto CDR, boot them on a PAL system in 50Hz, then flick a switch to force them to run in 60Hz as they were originally meant to. I did this with my MD2 and SCD2 for a long time. Plus, with an RGB SCART cable, there is absolutely no better way of getting a super crisp image.

Unfortunately the MD unit was in fairly bad condition to begin with. It had a massive crack on the outer shell, and when I opened it I found the RF shielding had been several warped – I’d bought it second hand over a decade ago, along with the SCD unit and games, for about $20, and my belief is that the previous owner fell on it, cracking the case and squishing the shielding.

Unfortunately opening I found that the tabs holding the power switch in place were broken, which is why the switch had a tendency to stick. It promptly fell out, forcing me to create a makeshift replacement out of a wooden clothes peg (I tried gluing the switch back in place, but the superglue leaked out and nearly fused with the electric box itself). Worsening the state of the system was that after I’d cut a hole for a flick switch, I used glue to hold it in place, except it leaked inside fusing it shut. So a useless switch. I had intended to use only one pole switch, but now needed two, and since the unit was so fugly already, I put them in plain view to give the whole thing a kind of Steel Battalion vibe, with switches, nobs and dials all over the place.


The soldering went smoothly enough, but I lacked a SCART cable. So I went to a local French store and traded a copy of Tail Concerto on PS1 for a French SCART cable. Its Sega reference was Model 3085 and it came with a massive black box in the middle, which I found odd. And it didn’t work. I had sound but no picture. So I took it back and got another one. Same problem again. Look at it, I wondered if the Black Box was somehow the problem. So I popped it open, and the 8-pin DIN plug, and checked the cables. I then decided to severe the cables in the box and re-attach them to each manually. This was fun, since the Red, Green and Blue signal carriers on the 8-pin DIN side were coloured Green, Orange and Red, whereas those on the SCART were coloured correctly, so I had to repeatedly tell myself: caps to the legs, legs to the dynamite. Good thing I watch TV, huh?

This worked, miraculously, except the screen was over-exposed, which I then realised was because in most normal MD1 SCART cables, there are resistors to reduce the energy from R, G and B signal wires, which were now missing. Which I feared would blow my TV up. Diagrams for an MD1 SCART cable can be found HERE.


I then did some googling and found this topic on Digital Press.

The Digital press website has of course moved since I found that topic, and using google to search it directly yields nothing, so I hope the above Google cache works, since it documents someone else’s solution to my problem.

This is what Dzerp discovered regarding said 3085 Sega cable.

“So here is what needs to be done if anyone else has the same problem with a Model 3085 Sega RGB cable. Cut the (+) connector one the left side of the board and connect it to the SINC on the other side (also cut). And presto. Have a really nice RGB picture.”

AAAARRRGGGHHH BAAAAALLLLLSSSS!!!!!

I had spent an entire evening rewiring the thing because I was too lazy to walk to my computer and search the net. And what I ended up with was a broken, semi-functioning cable, when a simple, single wire snip and resolder would have fixed the problem.

Well, I didn’t feel like buying another cable. And the machine was so goddamned ugly I didn’t think I could sell it anyway anymore. So I gave it to the guy at my local French store. For free. I also traded in the SCD unit for 30 Euro store credit, which I intend to put towards Vanquish.

And with that, my entire 16-bit and earlier collection is no more! All I have is my Saturn, N64, 3DO, CD-I, and modded Xboxs. Plus my PS3.

For anyone interested in doing this mod themselves, I recommend the Mmmonkey website.

Modding a SNES



I mod my UK SNES to run Japanese and American games in 60Hz. (Previously this post also spoke about the DSi, but I've edited it out since it's dated quite a bit)


Region modding a SNES

(click the images for higher resolution versions)

Modding a console is a quintessentially British thing to do; Americans have little need to do so, since by default they have things better than Europeans.

Since the beginning your systems have run at 60Hz, which meant full speed and fullscreen gaming, instead of nearly a 20% reduction in game speed and thick borders at the top and bottom of a squashed screen. You also tended to receive a hell of a lot more games than us, with maybe a few small exceptions. Recent years have seen a few more Euro exclusives, but really, unless you speak fluent Japanese, America is still the country to live for great gaming. Oh sweet glorious America, with your better weather, lower taxes and full speed gaming, how I wish I were there.


Because I hate region locking, today I modded a UK SNES. I could just use my American SNES, but this seemed like a fun thing to do. I used Mmmonkey's website, which features a collection of system mods taken from a variety of other websites,. What's great about it is, Mmmonkey redid all the photos, made the guides very easy to follow with a clean layout, and brought all of them together under one site.

I recommend everyone visit it and mod their systems.


Modding a SNES is quite tricky. It required the lifting of 3 pins, use of a 2.2K resistor, and a lot of patience. But now my system can be flicked between 60 and 50Hz, plus country regions. Of course some games like Mario RPG still won't work, but it's a nifty system to have, especially since I can now run cheaper domestic games in 60Hz!



I also had to widen the cartridge slot to accept US cartridges, which included taking my dad's power drill and removing the internal side tabs as shown in the photos.

In all, about 2 hours worth of work for the whole system, but damn, if it isn't one sexy bit of region free kit. The same aesthetic design as the Japanese Super Famicom, but able to play US cartridges, and running off a domestic power supply. Plus it runs nearly everything!


Very nice!
