Weird Bootleg - Family Basic Clone?

$

Hi, I've found a interesting bootleg cartridge.
I have many unanswered questions.
Could someone please help me to figure it?

Here's what I got for now:

It stays on this screen, probably waiting some keyboard input.
Looks like it's written in Spanish:

The cartridge PCB, component side:

On the picture I couldn't read the ICs identification, so I edited the picture to put it there.
I didn't know that the board had its own component identification "silkscreened" on it.

Solder side:

The PCB has some small patches on both sides, seems like it was intended to use a 8KB RAM and a 512KB ROM, but it is using a 2KB RAM and 64KB ROM. Maybe some last minute cost cut?

Interestingly, it looks like it would have some kind of expansion slot on the top, but it was ditched:

And, the dumped ROM of it:Unfortunatelly. I couldn't draw some decent schematics of it.
I didn't find a way to do it on my crappy cellphone yet, sorry...

I did some web research and could find a site with the Kingwon name, but it doesn't mention anything about this cartrige or any other thing NES / FC related. Does anybody have seem this cartrige or something similar?

Would the input that's being waited be the original Famicom Keyboard?
Maybe It could be possible to make it work on my clone...
Taking a look at the dump there are some references to a Kingwon bios and a Max Basic, seems related to the software on board, probably it's a clone of some other original software.

Any mapper that works like this one, so I can build a NES ROM and try on some emulators?
Thanks in advance.
