Hacking Help identifying R4 Clone

[ZeroNear]

Hey all,

Years ago, I bought an R4 SDHC Revolution for DS (NDSL/NDS) and used it to play games. It worked fine, but then I accidentally deleted the firmware (stupid, yeah). So now, I'm trying to track down the specific firmware that will allow me to play again, if it even exists. Obviously, I need to find the specific clone that I have, but I no longer have the box.

I've gone and tried a great number of versions and all it gives me is a "loader xxx" problem. So, I wanted to see if anyone knew exactly which clone this is so I can either find the right firmware or give up.

Here is a picture for context:

Thanks in advance!

it is really difficult to find out which r4 clone it is.
because years ago, R4 was very hot, there are more than 20+ R4 clone
