with latest svn, our NES driver now emulates the extended NROM368 board, an homebrew PCB which can handle 46K of PRG without bankswitch...
here, a bunch of snaps of the only program using this board to my knowledge
I think that only no$nes and a custom FCE build were supporting it so far, so it was interesting to emulate it. My hope is that having more emus supporting it we can help breaking the vicious circle "no software until a real PCB is available" <> "no hardware until software is available"
