From another site....." An important thing about the player is the Board ID code. This is the only trustworthy identification of the device.
The code is written in white on the green board. It's located usually behind a plastic sticker, near the minus battery pole. If you need help to open the player, see a tutorial here: Dissassemble the s1mp3.
If you are having problems to find your board ID, it may be behind the LCD cable. You might have to lift it carefully to see the bard ID. Seek everywhere! Both sides of all the boards! Some people take a bit of time to find the small white words. We qualify anything printed in white on the green printboard as the board ID.
Example :
MP-482C MAIN V8 " ........
I don't know if Admin will like this or not so Binh please let me know, but here is a link for many different types of FW. BE CAREFUL. See if your board # corresponds to any listed here:

If your board was never intended to support games, I doubt you will gain that feature w/ different FW, probably just a dead player. But good luck...
