This is a new revision of my UltraWii portable, named UltraWii Sakura!

Huge thanks to @Aurelio for making this portable possible with his direct drive board. This portable would not exist without him.

Here are the specs:

-OMEGA-trimmed Wii motherboard
-1S4P 3500mAh 18650s (~5.5hrs runtime)
-3.5" 640x480 IPS LCD w/ @Aurelio 's direct drive
-All-in-one BMS and reg board with digital audio amp and headphone jack
-Removable microSD card
-USB C PD and Switch charger compatibility
-Requisite RGB LED
-Orange squishy tacts, Switch joysticks, GC+ 2.0 with LRA rumble motor
-Recessed Sync and Reset buttons
-Wrist strap (if you're brave enough lol)

Dimensions: 140 x 75 x 26mm

Quick demo video

Notes:
-The Wii is permanently thermal epoxied onto the heatsink. This is the only way to mount it in such a tight space. Zero issues so far.
-3D printed button plates were replaced with 0.6mm PCBs and orange squishy tacts.
-The only glue used is to secure the USB-SD PCB and GC+ 2.0 to the back of the LCD and to hold the speakers in place
-Only magnet wire crosses between the two case halves. Much better than the prototype!

Holy guacamole, I'm in love! This is insanely clean, so small, and still has all the bells and whistles! Amazing work.

The r 101 should get 10 to 12 hours of battery life
Wut? 5-5.5 hours is the absolute best you can get with 4 3500mAh cells. Where are you getting this 10 hour number from?

Where's the case file's
Griffin hasn't made them available. Most people don't open source their designs.

What an amazing portable! Are those actual GameCube buttons? If so, how comfortable are they (being tall and stuff)?
