The .SRL is from Mario Kart DS (USA) (NDS) (Virtual Console), a Wii U software. Here is a patch to Mario Kart DS (USA), an NDS software.
I tried ndstool on the ROM, and one of the things it tells me is:
does anybody now what a "mask" ROM is? and how to convert it into a decrypted ROM?

Does anybody you know what the extra data is?

The header is identical between the retail .nds and the WiiU .srl
There is extra data in the WiiU .srl from 0x1000-0x33FF, 0x3600-0x3FFF
If you encrypt the .nds, the data from 0x4000-0x1FFFFFF is identical
Does anybody you know what the extra data is?
