Handhold Game Player - Model: FD2501P4

[Ju4N3r0]

Hello, I am new here.
I have just bought a MP4 that can emulate NES. I have been looking for the manual, drivers, firmware, etc. Searching I found it here:

http://freedata.com.cn/products_info.asp?code=4&id=105

... but the link for the manual is broken (same for software) . Neither there is a link for the firmware.
I found a topic on the "Sunplus SPMP3050A" at this forum. I think that this model is similar to mine, since I found it in the same page:

http://freedata.com.cn/products_info.asp?code=4&id=116

Any information will be helpful for me. For example, how knowing if my MP4 is a Sunplus SPMPXXXX?

Thanks
