MyMPx.org - Unable to get File Browsing in SRX-3.5.37

Happy New Year 2007 to everyone..

This maybe my 1st post at the forum, but i've explored and researched it to the best. Its the place to be in if you have any of those Cheap MP4 players.

My Player :
SONY TD-28
Core: PMA300_010; 2006-03-15
FW: SRX-3.5.37; 2006-03-24
Player has two speakers, two HPhone sockets, and joy stick.

My Research:
I came to know many a things going through this forum. I learned, one should never format/partition the player using the Formatting tool provided as it will leave the player with original chip's memory. Next I modified my theme, made it look much more cool, but guess its a big time taking thing. I even screwed my player, and then recovered it back by the much helpful dead player recovery guide. Finally what stuck my eyes, is the file browsing option.

Conclusion:
I went on with loverboy1981's instructions. Knowing its not for my player i tried. I even worked on ROLLEYFLEX's recommendation, but finally everything ended up in vein. I think its coz of those players being 641 and mine is 644, moreover the Firmware is SRX on my player where as most of the users have ACT.

Now, i wanna know is there anyone who has got file browsing on the player with SRX firmware. And if so, how? Even there must be a way to modify the firmware for getting file browsing. After knowing all this, i think i should have bought that iPOD clone, it has much more support as compared to any other MP4 player.

Last but not the least, cant we add games to the firmware, as i read somewhere the checksum is calculated by computer, there must be some space for extra games or telephone book(which i dont have). The size of my firmware is 6.2 MB.

Do help me guys, looking forward for doing somehting cool with this player in the New Year.. And trust me, after wasting so much of time on this player today, i got comments sayin i am lookin like "Mad Scientist" lol.

regards
Ayush
