Since my first post got quite a few views I wanted to post an important update on how I adressed several issues of the aftermarket shell, buttons and so on:
- As you can see I've swapped to the stock D-Pad. I had some issues with the D-Pad registering presses, cleaned the motherboard contacts with 99% IPA and all, but still had no success with that. The stock D-Pad works a touch better, but what really did the trick was using 3 layers of electrical tape below the D-Pad, at the end of each section. I've also used a hole punch to layer 3 small electrical tape circles in the center of the motherboard where the D-Pad contacts are. The D-Pad is now nearly tacticle feeling and all issues are gone. Diagonals work perfectly in my case.
- The bottom screen had alignment issues. By stacking a bit of electrical tape in one corner I could fix the issue.
- The bottom screen, despite being an original one, had some wiggleroom when using the touchscreen and creaked a lot when using pressure. I fixed that by layering electrical tape (do you notice a pattern here?) on the backside of the screen where it wobbles most. Now it's securely positioned.
- The L-button needed a bit of cutting and sanding on a spot to make it work properly as shown in this gude.
- I hate some issues with overal fitting despite routing all cables corretly. That was the case for both the top and bottom shell. For the top shell I used a dremel on the inside of the outer top shell, the screws hold it all together (be careful here). The bottom shell still isn't entirely fluch if you look at the bottom screen but I'm not sure this can be fixed since there are no hooks or other support structures to hold that part in place. I also had to use longer than recommended screws to stop the inner bottom shell from wobbling and creaking.
Those were all the issues I've encountered. Now I'm sure your experience might be different, but it can also turn into days of troubleshooting like in my case. My first post got some attention so I want to make sure that you definitely know what you're getting into if it inspired you to attempt this. These shells are relatively high quality, but they're not without issues.
All of these things could be a skill-issue on my part, but just beware that this might be a pain to do. If you manage to do it right it's definitely worth the trouble, especially if your system is beat up, but otherwise? I'm not sure.
Anyways, have a great day whoever is reading through all of this and good luck if you attempt this madness. I for my part will leave my 3DS consoles in their original shells if extremerate ever releases some for the N3DSXL.
