This is a goody I managed to upgrade my 9.0.43 player with it. Has some fixes and new games.

USE AT YOUR OWN RISK IF YOU TRY THIS AS AN UPGRADE THERE IS A GOOD CHANCE YOU WILL FRY YOUR PLAYER. THEN THERE WILL BE THE YELLING AND THE CRYING AND THE PLEASE HELP ME...... AND IT WILL SUCK TO BE YOU.

On the other hand if your 9.0.XX player is already dead then this could be what you are looking for. Then there will be the laughing and the crying and it will be good to be you.

Thanks to ErikO for sending me this.

Hi,
can i install this firmware on player 1.5" atj2085w samsung 619 (3.5.37 actual) please ? difference with 3.5.37 and 9.0.50 ? drivers screen ? processor ? bootloader ?
if you have an reponse for me...
Thanks a lot T.

Thierryd, No no no for as start this is for 1.8 LCD and the 9.0.XX series firmware will kill a ATJ2085 chip player. 9.0.XX series firmware is for ATJ2091, ATJ2097 and CTW500 chipsets.

For the ATJ2085 3.5.37 is the highest you can go.

Oh ok thanks a lot for response, this firmware is more complete and customizing, (the 3.5.37 is not full customizing and limited for themes and 2085 is slow i think) , i search a player with this processor but the processor and firmware not marqued on buy selling .... the frequence processor and run fast with an 2085 or an 2097 ctw500 ... serie please ?
player 3.5.37 can play ogg format and 9.0.50 play it ?
thanks,T.

Thierryd, I have a CTW500 player was originally 9.0.43 but i found an upgrade to 9.0.50. the player does run a little faster than the ATJ2085. These new chips were designed to support new features like larger LCD screens up to 2.2 inch, USB 2.0 High Speed data transfer and SD cards.
Here are some players that use these chips
