Merging Firmwares --> File Browsing

[M@ce]

Hey guys,
as the topic says i'm trying to merge Firmwares to add File Browsing.

My thoughts about that:
It should not be possible to kill the player with the merged firmware, because the only file i'm going to change is the Music-App-Part. Everything else (USB, Main-Menu and whatever will remain the same). So the worst case would be that the player crashes when you try to access the Music Player.

What i need:
Firmware 3.5.37 (WITH File Browsing) for a 1.8" nano clone
Malldebella says that his player has it: http://www.mympxplayer.org/album_showpage.php?pic_id=91
It's nearly the same like mine (2GB nano clone, 1.8" TFT --> NOT CSTN, USB at the side, earphone at bottom, 3.5.37 but WITHOUT File Browsing)

I contacted him, but he doesn't seem to want to give his Firmware to me.

So, if you have this player (or maybe the same with CSTN instead of TFT), then tell me. Only thing, which is necessary is: FW from a player with 1.8" display and FW 3.5.37 WITH File Browsing.

Hope anybody can help me?
Maybe Malldebella?
