Right after a rather slow start I’m finally getting somewhere. I purchase 2 Gameboy DMG-01 to gut and managed to fix both of them so that has generated my funds for the project. I eventually ordered 2 new shells from China so no Game boy will be harmed in the process.

My first problem was with the WIFI I bought a cheap £2.50 delivered adapter Retropie 3.2.1 didnt have the driver.

So I used

lsusb

this listed the offending device after a google search

Bus 001 Device 004: ID 148f:7601 Ralink Technology, Corp.

as needing a MT7601 driver

I used the command

sudo wget https://github.com/porjo/mt7601/raw/master/src/mcu/bin/MT7601.bin -O /lib/firmware/mt7601u.bin

None of this is my work I found a guide on the following site

https://www.raspberrypi.org/forums/viewtopic.php?f=91&t=89565&p=833452#p826699

I then modified

sudo nano /etc/network/interfaces

WPA/WPA2

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
auto wlan0
iface wlan0 inet dhcp
wpa-ssid “NETWORK_NAME”
wpa-psk “NETWORK_PASSWORD”

This works great apart from if I change locations and the adapter cannot find my network it keeps looking. I’m sure there is a easy option to sort this.

Next I bought a usb hub/ethernet adapter so I can de-solder all the usb and rj45 connectors to make it smaller in height.

This would be great for a Zero

After a bit of a faff I managed to get the external Ethernet working I changed the contents of

sudo nano /etc/network/interfaces

auto lo

iface lo inet loopback
iface eth1 inet dhcp

allow-hotplug wlan0

auto wlan0

iface wlan0 inet dhcp
wpa-ssid “xxxxx”
wpa-psk “yyyyyy”

The important bit was changing iface eth1 inet dhcp which prevously said iface eth0 inet dhcp

I have decided to use tactile switches under the Game Boy keys I may use a pcb for the directional control I bought some good quality ALPS ones which have a life of 1,000,000 cycles.

Im going to mount them on vero strip board so I can move them round easily. I will then wire them into the chip off the USB pad I’m going to take apart. If the joypad area matches up I may superglue that to the board and use that instead.

I’m now on the hunt for a small enough battery pack I think my power bank may be too thick.

Has anyone used those extended battery’s for the S3 or Note 4?

Thanks
