Looking at the Wiki https://wiki.nesdev.com/w/index.php/CNROM, I see that CNROM can have 16kB or 32kB PRG.
I guess the way to tell which is described here:
Quote:
16 KB PRG ROM : 'SL' connected, 'CL' disconnected.
32 KB PRG ROM : 'SL' disconnected, 'CL' connected.

What are SL and CL? are those in the iNES header?

Disch's mapper documents don't say anything about this.

SL and CL are solder pads on the PCB. There is no dedicated field for them in the header apart from ROM size being 1 or 2 16K units.

Oh right, so even for carts that switch whole 32kB PRG banks the iNES header will count them in units of 16kB, right?
Thanks!
