Well, it has, and quite alot seems, there appears to be quite a few skins out there for the various players, so i will now dump here all the bits i have found and let you all have a bash at finding out how they actually did this.
Modding these players at the moment refers to changing the look of the players User Interface not adding functionality, emulators etc, but this may be happening, i dont know, more research will need to be done
One tool that i eventually found, after many dead links was a small app that basically rips the "HXF" file to pieces, revealing all the core files that make up the firmware.
This tool is amazing but it is all in Chinese and i do not yet know fully how to use it. Basically it can extract all the files out of the HXF, you then work on them, when done it can pack them all back together again into a new HXF file.
This is the HXF file extractor: UPDATED FILE WITH COMDLG32.DLL and COMDLG32.OCX INCLUDED IF NEEDED
NOTE: this is the enlgish version of the editor kindly translated by Natsukawa

Download and of course "virus scan" the file.
so this is what i have so far figured out.
1. This tool needs to be placed in the folder along with the HXF file you want to work on
2. Double click to open it (see image below)
3. click the left button on the top and select the HXF file
4. The program appears to do nothing but take a look in the folder and you will see it has created a new folder called "out_hxf"
5. Have a look in the folder and you will see several more folders like:
- #codecs
#game
#system
#user_data
codecs file contains files with the extension ".dl", and you wll recognise the file names whe you see them
Game contains a folder per ame on your player, in the folders are files for the game
system has folders called code, font and res
- code has more "dl" files with names reffering back to the "game" files
font has some files called "BMF" .. bitmap fonts file ???
res is the main images folder and has several images and sub folder of images
so that is all the files i imagine from here you make your changes, change images etc or what ever.
when done rename the "out_hxf" folder to "in_hxf" and open the app again
now click the right hand button, a save as dialogue appears, call the new firmware a new name and ok it
the app will then compile all the file into a new HXF file, when its done, look in the folder and its is there
WARNING
i do not know if this works at all, i do not have a player to test on
try it and see if you are brave
i take no responsibility for ANY problems AT ALL for any problems
This may not work at all but it is worth a try

These are various and good places to look around and try and find out as much as possible on how to mod these players

like i say, this is only first steps on all this and it is now up to all to find out as much as possible
good luck all and post any info you find - the more the better
