In the opening title of Batman Return of the Joker, and also in the first level, the noise channel drowns out the other channels.

Not sure why yet.

If I change the maximum envelope volume from 15 to 1, it sounds better, but that doesn't seem like the right thing to do, given that other emulators without this problem use a max volume of 15.

The current design doesn't allow for easily integrating the DMC channel support.

Frame rate drops from a constant 60 FPS to... something like 10 FPS?

The only way around this seems to be to downgrade to 2.0.9, which I've done like this:

$ curl -O https://libsdl.org/release/SDL2-2.0.9.tar.gz
$ tar zxvf SDL2-2.0.9.tar.gz
$ cd SDL2-2.0.9
$ ./configure --prefix=/usr/local/Cellar/sdl2/2.0.9 --without-x
$ make install
$ brew unlink sdl2
$ rm -rf /usr/local/Cellar/sdl2/2.0.10
$ brew link sdl2

Need to figure out why it's slowing down so much. Haven't looked into it at all.

This cart adds extra sound channels. They need to be implemented, but the current design doesn't allow for the APU to clock cartridge sound channels or retrieve samples from the cartridge.
