CNROM boards manufactured by Nintendo don't support more than 32 KiB (four 8 KiB banks) of CHR. But some unlicensed CNROM-compatible boards have 128 KiB, and I'm guessing the emulators replace the 74HC161 binary counter with an 8-bit latch as described here.

The PowerPak has 512KB of VRAM. This ROM needs 1MB.
