This is an update from an earlier post Part 1 can be found here: Ebay SNES Part 1.
The 4.5mm gamebit arrived giving me the ability to open up the console. Which I did, arriving also a cheap Chinese video capture USB dongle, I’ve not played with it much yet and I'm not expecting much from it either.
Anyway back to the SNES, I opened it up, turns out to be a SNSP-CPU-01 motherboard, took some pictures of the inside for my own reference they can be found here:Photos on Flickr, although it wasn't needed I went ahead and changed a few of the Capacitors anyway with some I already had, There's not a whole lot inside the SNES so it's not a big issue, just thought I'd do it while I had it open. here's a quick list of values:
| Value | Voltage | Amount |
|---|---|---|
| 47uf | 16v | 1 |
| 2200uf | 25v | 1 |
| 33uf | 25v | 2 |
| 10uf | 50v | 5 |
| 2.2uf | 50v | 1 |
Other models of SNES may have different components, these are just what mine has, also being one of the early PAL models yours may be different. I did not change all the capacitors as I didn't have all the ones I needed so just changed what I had(2200uf, 47uf, 1x 33uf) the others I need to order up along with some LEDs. I'm using just standard electrolytic radial capacitors and not the SMT ones.
Progress!
Few other things I completed while the SNES was in pieces, PAL SNES consoles are unable to use USA/JPN control pads and also some 3rd party imported pads as standard, this may not effect all PAL units but it Did with this one, There's two methods of fixing this, one is a mod on the control pad PCB itself which involves added two resistors, which I won't go into, It makes much more sense to make the console universally accept control pads from any region. And this is very easy, Just Bridge 4 points and that's it, a little bit of wire or legs from a resistor or capacitor work great too. Here's a Picture of the Controller port PCB with the points to bridge outlined in red:
Also in the above picture, you can see the red power LED I'll be changing this to a Green LED because it fits the theme/look I'm going for and I like Green better, there's a 160ohm resistor in series with it(2 legs top right of pic). After doing this quick mod, I tested with a control pad from a retrobit "RetroDuo" which did not previously work with the PAL SNES, and now it works just fine.
The Second thing I done was widen the cartridge slot to accommodate US Game Carts, yes, I could have got adapter/converter but meh didn’t want to, and yeah i could have got a US SNES but meh they're ugly as all hell, and SFCs are a bit more expensive than I wanted to pay right now but would still need a slot mod or converter.

Look a bit rough, but then I did use a mini hacksaw/blade but it's by far not the worst job I’ve seen, I'll tidy it up somewhere down the line when I get to the aesthetics sand / smooth the rough edges etc, along with extending the cart slot flap to stop dust getting in.
That's all for now, but there will probably be a part 3 and maybe even 4, who knows! <place holder for link to part 3>
