How to Custom my bluesky BMP9108 ?

[moouche]

I' ve just bought my bluesky BMP9108 musiv/video 4Go player today.
(Rockchip USBDISK)
and 2 hours later , i was looking for a way to hack it, crack it, to custom it....

So here is what i know:
- I copied the file "rkusb.tag" into the root player
>>>So now, i can see a new drive with folders ans .bin files

like this:



SO WHAT NOW ???

i'd like to change
- the font
- the bootscreen
- the lock screen
- the usb screen
- the theme
- the background
- the icons

i'd like to add
- others games to the player
(there is juste one game...named "Gobang" and it's so lame)
- softwares (if it's possible to add new programs into it)

so here i am, i've found the system drive but i don't know what to do now to custom my player

Can someone help me about it?
Anybody already customed the BMP9108 player ?

I looked all this afternoon to custom and add game to my bluesky BMP9108 player,
and this forum is pretty much the only thing i found about "hacking mp3/mp4 players"

Nobody talk about the "bluesky BMP9108" on the web , i hope you will help me out

thanks
