I posted a new topic but should have probably looked in here first.
So if its the worst firmware are there any advantages to moding this player.
I am asking because I have a similar MP4 player, here is my MP4 Player pics and info:

It's a 1 GB MP4 Player with 1.5" 64K color screen
This is the information I found in the System info option:
2005/12/16
3.5.35
2006/02/10
JTYMDO46V4
This is pretty much the same MP4 player, right?
If we can't change the background or layout can we improve its performance.
For instance it is slow. When I press the next button while I am hearing a song, it takes forever to play the next song.
It also fades out which adds more delay time.
What mods can someone recommend to improve our MP4 player.
Thanks in advance to anyone that help out.
