Hacking Is this a clone? And does anyone know what firmware might work with it?

Hey there, so I found this R4 cart in a drawer a while ago, if feels like a friend of my brothers might have left it here and they don't seem to be missing it. It came without an sd cart unfortunately.
Anyways, going by some other thread, it looks like the real thing, though its an older cart apparently. Unfortunately, its probably too old to be turned into an ntr boot cart, so I thought I'd at least try to get it up and running.
That image I got online, but I opened mine up and its identical to the image.

Tried putting the wood firmware (both the one mentioned in the all firmwares thread and the most recent v 1.62) but its stuck at a black screen saying "loading..." when starting up. So it might be a good looking fake?

I tried the firmware for r4ds.com too, same loading screen though.
If anyone was able to cut down the list of potential cart firmwares to try from

that would be a great help.
I also already formatted the sd cart.

Or if anyone got any other ideas?

The original R4 only supports microSD cards with up to 2GB storage, formated as FAT.
Do you have the white "shine" at the bottom of the sticker?

oh... well that might be it then, the smallest sd i have around is 8gb...
and yes, it has the shine, just like the picture.

I guess if it doesn't work with ntrboot and could only hold 2gb for games, I'll just put it back in the drawer.
