Nintendulator now respects the NES 2.0 header values for PRG RAM and CHR RAM sizes more closely; their default maximum sizes have been updated from 64KB to 1024KB and 32KB to 256KB, respectively. The logic for setting banks will now obey these limits, so an NES 2.0 ROM which indicates zero PRG/CHR RAM will prevent you from mapping any; consequently, an NES 2.0 ROM with both zero CHR ROM and zero CHR RAM is invalid and will report an error when loaded.
