[¿HO?] Homebrew Emergency Launcher

Hi everyone

A few people have experienced bugs with the grid launcher which have left them unable to get back into a launcher to FTP in and re-upload. This means the only thing you can do is to take out the SD card and put it in your computer, which is inconvenient or not always possible. Developing a launcher is also problematic because if you make a change which prevents the launcher from running (which has happened to me hundreds of times while developing the grid launcher) then you have to use the SD card reader to fix it.

So, I came up with the idea of a homebrew emergency launcher. The attached app is a highly stripped down version of the homebrew launcher. It replaces boot.3dsx on the SD card, and allows you to boot to a backup launcher if something goes wrong with your main launcher. It adds about a second to the boot time for the launcher, as the emergency launcher opens first and then it launches either your HBL 3dsx or an emergency 3dsx.

Installation:
Rename the boot.3dsx file already on your SD card to boot1.3dsx
Place some other launcher or FTP client in the root of your SD card and call it emergency.3dsx
Copy the file boot.3dsx from the emergency launcher archive to the root of your SD card
Usage:
Boot up your homebrew hax as usual
If you do nothing, then boot1.3dsx will be launched (your normal launcher)
If something goes wrong with your launcher, hold down the right shoulder button while launching your homebrew hax
This will cause emergency.3dsx to be booted instead
When changing or updating your launcher, remember to copy it to boot1.3dsx not boot.3dsx, or you will overwrite the emergency launcher.

I have tested this on Ninjhax 2.1 on a 9.9 EUR N3DS. I have no idea if it works on other devices. Feel free to give it a try. If it doesn't work for you, just delete boot.3dsx and emergency.3dsx, and rename boot1.3dsx to boot.3dsx.
