This cart is basically the same as R4. There are a few differences and some other additions seen below:

All SD read/write (0xB9/0xBB) has no sector shift.
0xBC does an XOR on the last byte:
- BC XX XX XX XX 00 00 YY
- XXXXXXXX = sector address
- YY = XOR of every byte in command reg, so BC EOR XX EOR XX EOR XX EOR XX EOR 00 EOR 00
0xB4 works... on SD cards that aren't SDHC. because sector address must be <<9'd. Kernel uses normal SD RW for games.
- Save read/write commands on the R4 doesn't work on the Ace3DS+ if you do this for reasons not exactly known. Wood ports by some old devs used SD RW for saves and 0xB4 for ROM.
0xB6/0xBF seems to be supported... kinda. It's different from how the R4 does it. No idea at all how it works yet.

This guide will include a step-by-step guide on how to set up an board running Armbian to act as a gadget device (similar to how it's been advertized with the Pi Zero)

Prerequisites

You will need a:

Armbian supported board with an OTG port
A temporary spare monitor, USB keyboard and display cable (or serial, if you'd like that instead)
USB cable

Backup android app, data included, no root needed, with adb

Note: This gist may be outdated, thanks to all contributors in comments.

adb is the Android CLI tool with which you can interact with your android device, from your PC

You must enable developer mode (tap 7 times on the build version in parameters) and install adb on your PC.

Don't hesitate to read comments, there is useful tips, thanks guys for this !

How to install and print on a Thermal Printer USB 58mm / 80mm. https://twitter.com/juancarlospaco/status/1128781387782344710/photo/1 https://twitter.com/juancarlospaco/status/1128732835131678720/photo/1

Why?

This kind of printer is cheap as hell compared to all other kind of printers, including ink-tank and dot-matrix.
