Hello,
First of all I want to apologize for my english...
I probably found a firmware for Sunplus SPCA536 Chipset.
If you have dead player with that chipset and know how upload new firmware to your device it could be helpful ;]
The firmware file could be found here

If someone could fix his player with this file please help other people and write how you do that.
DO NOT UPLOAD THIS FILE TO WORKING SUNPLUS PLAYER!!!
