pre9otherapp is the otherapp payload which can be used on firmwares earlier than 9.2 to launch an arm9 payload from the SD card directly.

Note: The latest release can be used on all regions and 3DS consoles but works on all between 4.0 and 9.2 (use usr2arm9ldr for pre 4.0 firmwares).

Installation

The otherapp can be used with soundhax to launch an arm9 payload such as safeb9sinstaller. It looks for a arm9.bin on the root of your SD card.

Installing

Get the soundhax file for your console and region.

Get the arm9 payload, safeb9sinstaller in this case.

Put all the files, including otherapp.bin, on the root of your SD (for safeb9sinstaller, just copy the arm9.bin from the zip).

Launch soundhax, if everything goes correctly you will be in safeb9sinstaller, this might/might not work on the first try.

Building

You need to have devkitpro installed to build this.

CTRULIB isn't required.

Simply open terminal and type make to build this project.

User guide

An edited version of svchax(memchunkhax) and brahma(firmlaunchhax) has been incorporated to gain arm11 and arm9 execution.

So it first uses memchunkhax to gain arm11 execution, then maps the arm11 and arm9 payload and then perform a firmlaunch.

On Pre 4.0 firms use usr2arm9ldr to gain arm9 code execution.

Changelog

v2.0

• Use usr2arm9ldr to support pre 4.0 firmwares.
