So for whatever reason I did not really like the ways you can choose between different files at the moment because most involve slow config files or require screen_init with backlight enabled creating a short screen flash which I find somewhat irritating.
The project is located right over here:
https://github.com/FIX94/arm9select
This is a very simple A9LH binary which allows you to hold down any button on start to select the file you want to boot, files should go into /arm9select and follow the pattern of a.bin, b.bin, start.bin etc. If no buttons are being pressed or the file of the button you hold is not found it will use default.bin. If you want any of these files to also have screen backlight enabled, create files in the /arm9select folder in the pattern of a_bl, b_bl, start_bl etc. Again, if no buttons are being pressed it will check for default_bl. This project was made with the expectation of using my arm9loaderhax fork which does not enable the backlights by default, you can find it over on https://github.com/FIX94/arm9loaderhax.
Maybe to somebody this is useful.
