Having the games feature might be full compatible with your player.
What does the startup/end and menu main images look like?
I have a player similar to yours with the same casing, but can't say it uses the same board as your player though.
This is the firmware here:

It doesn't have games on it though.
Flashing your player with an incompatible firmware will result in a 'dead' player (as you know already). If you are prepared to keep fixing your dead player and recover it then have a look through the firmware section and read the notes to see if they have games mentioned.
