So, after researches, it`s clear that new Gameboxes have a new firmware that can read other files in Micro SD card. The new firmware is V1.0Build85b. Oldest ones is V1.0Build7c1.
It`s a shame that the gamebox.hk site does not have the upgraded firmware for the older ones. They even don`t give any responce when we contact them by e-mail
There’s no way to dump the new firmware? Which rom’s formats can it run?
It can run .gba – cps1 – cps2 and pgm type mame roms and neogeo most of them zip
Apart from gba, I had no luck with cps3
check this out , looks like a different version of the game box.

To check the version, just hold SELECT START on startup and you’ll see the firmware version.
Once you’ve confirmed the version number is V1.0Build85b or HIGHER…put these bios files (google for them) onto the root of your SD card:
pgm.zip and neogeo.zip
Then you can play some cps 1 and cps2 games and of course some neo geo games.
So simple to do this
Needed
1x USB Cable
1x Gamebox no power supply or AV Cable plugged in
Press L1+R1+Right on the Joypad, keep holding while plugging in USB to PC and wait for The driver to install and your Done…. access to the internal memory
