RecalBox as MP3 Player

[benobi]

Hello, this is my first post here.
I built an MP3-Player on a Raspian-Distro.
Now it is the time I would like to put it on a fast booting system so I choose recalbox. But I cannot install git or something else I need for using my player after boot.

Could you please make a distro where this player will be started after autoboot? You could call it special mobile recalbox with music or something. The player uses a 2 line display with 5 buttons from dfrobot and will try to mount 2 sd cards from usb-sdcard readers. All you need to add "extra" is a cheap usb sound card and set the hw-flag for sound to 1 or something. Would you please, pretty please do that? I will continue working on it meanwhile.

Besides, it's here:

Thanks for your consideration.
