Question Doubt about relocating the MX chip and custom regulators

[patricksouza472]

@ShockSlayer @Gman @cheese @Shank I'm currently thinking about making my first portable, maybe the first ever done in my country (Brazil). It's gonna be a GC Portable but using a Wii motherboard cause Nintendont is way more compatible with games than Swiss. I've read the trimming guide multiple times, and I feel comfortable with most of it, but there's this MX chip relocation I can't figure out how to do properly. The circuit protection/battery current limiter Pic has a pink line, but it does not tell what to do. There's just a B+ point, which i supposed to be Battery Positive, is it right? Also, about the custom regulators, should they be soldered to only one of the points shown in the guide, the rest being alternate points or should I solder it to every same-colored point? I currently have access to a 4-layer and 6-layer board, being this mod strictly for GC games I won't use WiFi or Bluetooth, is there any difference between them? I know 4-layer boards generate less heat and consumes less power so the battery lasts longer, but is it any easier or more difficult? Sorry you're having to spoon-feed me, but I couldn't find any pics from the "finished" board
Thanks in advance!

Alright so, the MX is not a required relocation, you can choose to just leave it off. As for the lines, make sure you just connect the same colors together between the mx and the wii.
As for b- and b+, those are for a separate battery to power the real time clock. That should be the CR2032 battery that was in the tray by the bottom when you disassembled the system.

@cheese OK, I got it now. I'm gonna give it a second thought and see if it's worth the hassle, I don't even recall any game using RTC besides Animal Crossing. And what about the custom regulators, how should I connect them to the board? Just solder output line to the any solder point among the listed? For example, the 3.3v regulator to any point marked in red, 1.15v to any point marked blue and so on, is that it?

If you use a 4 layer, you can connect your regulators to any point labeled with that voltage. The 6 layer guide has a note about one extra connection you need to make.

Thanks a lot! Guess I'll go with a 4 layer, since I don't plan on using BT, also longer battery life and less heat are surely a huge bonus. Now I just gotta focus on a case design

If you're wanting to 3d print one I highly recommend Fusion 360. Relatively easy to pick up while very powerful.

Thanks @jefflongo, I will take a look at it. Awesome mod you did BTW, surely inspired me
