Firmware with games?
 

Hello, I have a 4GB mp4, but the only problem is that not have games and I wonder if you know some firmware that will bring games and work on my mp4. I tried installing several firmwares with "Media Player Upgrade Tool" and "Mass Product Tool" but I get errors when trying. The MP4 is exactly this:
Reproductor Portátil Mp4/mp3 8gb Jumbo / Ultima Generación - BsF 240,00 en MercadoLibre

In general:
display: 1.8
firmware version 1.0.02
internal 4GB
microsd slot up to 4GB

Or if you can recommend a better firmware would serve me well.
Sorry for bad english :)
