Dumping Batman Return Of The Joker using Kazzo NES Dumper

[WarMasterXX]

I'd like to dump Batman Return Of The Joker (NES).
I've got Kazzo NES Dumper, but it doesn't look like the program it uses to dump cartridges to ROMs (anago) doesn't support the mapper the game uses (
Sunsoft 5 (69)).
Any suggestions on what to do?

EDIT:
It looks like anago DOES support the right mapper, in the form of fme7.ad. I'll edit again confirming whether it works or not...

EDIT 2: I DID IT!
Here's what I had to do:
-Download "sunsoft_fme.ad" and "sunsoft_fme.ag" from here: https://github.com/arantius/anago-scripts
-Place them in the same folder as anago
-In anago_wx, select "sunsoft_fme.ad" as script
-THIS IS THE IMPORTANT PART!: Set BOTH Program ROM and Character ROM to 2x
-To make sure it's a good dump, download "NesToy32" from here: https://www.zophar.net/utilities/nesaud/nestoy32.html
-Place the dumped ROM in the same folder as NesToy32
-Run command prompt, go to NesToy32's folder, and type these commands in order:
1. nestoy -c
2. nestoy -rep
3. nestoy -c
IT WORKS!
