Super Famicom / SNES build

@ruckage It is an idea I have been considering trying to tackle. I have a few things in progress that I need to finish, but I may give it a try afterwards.

Fingers crossed then :) , I'm assuming if you attempt it it would be done as a separate view? I can see it being very popular if added.

I'm thinking of faking it for my setup by giving each game it's own system, that's feasible for me as I don't intend to have every single game on it. Once you click on a game the gamelist view would contain that single game to launch and info/art about the game. This would be a bit time consuming but would look pretty good I think. The only thing that I'm not sure about is what impact that would have on the startup time as more systems seems to slow things down - or would that not be an issue with only 1 game in each system?

@ruckage I love those labels. What sort of cutting machine did you use? Much nicer corners than my hand cut label that I used on my build.

It's a silhouette cameo, really good machine (one of my favourite gadgets).

I've decided on how everything is going to fit now. @AndersHP will be pleased to hear that I'm trying to be as non-destructive as possible and although some parts are being desoldered it would be relatively easy to turn this back into a functioning Super Famicom in the future.

The rpi will be placed at the very rear of the console behind where the power/display port panel is. There is very little clearance there so I had to modify the rear panel slightly by cutting off part of the screw tabs using a rotary tool, this won't affect stability when screwed into place as the screws only prevent the panel being pushed inwards.

Note: For others attempting this the only way to remove the rear panel is to de-solder the power connector.

Rear Panel

Rear Panel Modification

Panel secured with screws

When positioned correctly and raised using standoffs the rpi hdmi port will line up perfectly with the 'multi out' hole on the rear panel, unfortunately I found its bit too far inside the console to reach compfortably so I needed a way to extend it outside. I found these connectors which are basically an HDMI throughport, no idea what use they are to most people but they are perfect for this:

HDMI Connector

It wouldn't quite fit though the 'multi out' hole so I had to trim the top and bottom - leaving a step in the bottom so it won't push all the way though. Admittedly it looks a bit of a mess after this but once installed you can't see my hack job.

HDMI Connector Modified

It does stick out but it doesn't protrude past the main body of the console. This seems a good compromise to me as it allowed me to use the original rear panel with minimal modifications.

HDMI Connector installed

Here is how the RPI will be placed, it's raised on stand-offs which will be screwed into place. There is enough room beside the USB ports to fit right angle USB cables. The only problem is there isn't enough room to connect a Micro USB for the power so instead I will be soldering power leads directly to the test points on the rear of the RPI.

Placement

I've also begun work on the controller ports. These will basically be large SNES shaped USB ports. I won't need the PCB on the rear of the ports so I've de-soldered it so that I can solder directly to the pins. I've placed a new LED for the power and as there is no PCB to hold it in place now I've secured it with a cable tie.

I have 5 labels spare, I'm happy to give these away if anyone else would like one for a similar project - you'd just need to cover the postage costs.

@ruckage I would really like to use this label for my upcoming SNES project. Is there still one available?

ruckage · 15 Aug 2017, 11:34

@martino_heat
Hi. Yes, they're still available so you're welcome to have one. What country do you live in so I can find out the postage cost for you?

I've been working on a concept for a SNES theme for this, I know I will probably end up trying to mimic the snes mini when its released but wanted to see what idea I could come up with myself. This is a very early wip, the background is a placeholder at the momentl. I'm quite pleased with how the SNES itself looks (just needs a few tweaks).

This would obviously be the system view but wouldn't it be cool if we could use the carousel in the gamelist (hint, hint @jdrassa ;) ) , it would be awesome to scroll through game cartridges like this.

I agree @ruckage @jdrassa .....A horizontal/vertical gamelist view that adopts the marquee tag maybe? making way for wheel art or cartart.

@ruckage Great! I live in Germany. Can you please contact me via Email -> MartinoHeat@gmx.com?

@martino_heat
I've sent you an email.

I've finished the controller extension leads and soldered usb leads to the control ports.

Here is the snes extension lead plug dismantled and the wires cut.

I removed the pins and soldered them to the end of a usb extension cable.

The pins were re-inserted back into the plug and a cable tie was used to prevent the wires from being yanked out.

This is the finished USB to SNES extension cable.(I made 2 of them).

Next USB leads needed to be soldered to the control ports so that they can be connected to the pi.

Now I can plug any usb controller into my extension leads and connect them to the super famicom. Not as authentic as using real controllers but it gives me more flexibility and I still get to use the control ports on the console. I've given them a test with my pokken controllers and they work perfectly.

ruckage · 7 Sept 2017, 18:27

I think I'm almost finished. Just the theme/software side of things to do now.

The pie is connected to the original power input via the power switch - it's actually soldered directly to the underside of the rpi using the test points (I think it was ppt1 and ppt6) as there wasn't room to power it via the microusb.

The switch on the proto board is the original Super Famicom reset switch and is positioned in the correct place so that it is activated by the reset button - this will be used as a shutdown button (the brown wires connect to it).

Finally I added a small fan (but no heatsink), this seems to be enough to keep it cool.

@ruckage

Very cool! I've been wanting to do something similar in the NES build I'm doing. I hadn't seen anyone adapt the ports like that yet. I'm Glad it can be done!

ruckage · 13 Sept 2017, 20:00

@snakerake

Thanks. The ports work perfectly and it gives me more flexibility regarding what I can connect to it. And if I want real snes controllers I can either convert them to USB using the circuits provided at raphnet or buy a SNES to usb converter.

Wow, this is awesome - any progress on this? I'd love something like this for my build.

@jackal123uk

Sorry for the late reply. Sadly it's not really feasible yet, I could do the system select like this but I'd really want the carousel available in the gamelist as well so that the cartridges would represent actual games. Hopefully in the future though as it's been mentioned as a possibility a few times.

I have released a SNES mini theme though that is based on the SNES classic which might interest you.

Here's is a video of my pretty much finished build using the Snes-mini theme (already posted in my snes mini theme topic but I figure it belongs here too.).

ruckage · 4 Oct 2017, 13:42

I made a small addition inspired by @jackal123uk build and added an SD extension cable that is accessible from the port on the back, that way I won't need to dismantle the whole case just to get to the sd card.

This is the one I bought: https://shop.pimoroni.com/products/microsd-extension-cable
It seems to be the same as the one @jackal123uk used but is much shorter.

I made a bracket from thick greyboard (just very thick card) which I glued to the SD extension cable and drilled mounting holes into the Super Famicom case so that it could be secured in place.

jackal123uk · 6 Oct 2017, 20:43

@ruckage nicely done and good find with the shorter cable - I'm gonna pick one of those up for myself.
