I spruced up my Sd2snes a little.
I own a revision G model. Revision F and earlier had an issue with MSU-1 audio (explained
here if you're curious). Revision G had a quick fix for this issue, but it was still an issue. Revision H and later completely fixed the issue. The issue only affects MSU-1 audio, so if you don't use that then you can just ignore the problem. Otherwise, it's a fairly simple fix if you know how to solder.

Since I had revision G, it required the extra step with the bodge wire. I had an issue with FB341, I might have heated it up with the iron too much and the solder contact broke off of one side (not the pad on the PCB, the solder contact on the part itself). Rev G had a bodge to one side of FB341, so possibly that weakened the part. Luckily, you're suppose to remove FB342 and short those pads, so I was able to use FB342 to replace the one that I broke on FB341.
Since I ordered the PCBs from OSH Park, I got three of them. Knowing this, when I ordered the parts from DigiKey I ordered enough to populate the three PCBs. I only needed one PCB for my own Sd2snes, so I have two spares if anyone needs one. I'll give them away for cost plus shipping.
While I was doing this mod, I took the opportunity to do something else that I've been wanting to for a while. I got my Sd2snes with a standard grey case, but with LED pipes installed. I had to put some tissue in the green LED pipe to dim it because the LEDs on this thing were so bright they would blind you. But now the firmware actually allows you to dim the LEDs, there's 15 different brightness levels IIRC as well as OFF. So with that I've been wanting to put it in a clear case that I had on hand. The only thing is that I had to carve out the extra cart edge pins, the SD card slot and the USB port. I like it a lot better in the clear case, I like to see the PCB and also it works out good for the LEDs. Also, the screws were kind of stripped out on the original case making it a PITA to open. You don't open it regularly, but you do on occasion to change the battery (it has a real time clock). The clear case snaps shut and doesn't require screws. Unlike Famicom carts, it's very easy to open.
I'm not going to put labels on it, I like it clear so I can see the PCB.
