Looking at the iNES 2.0 header specifications, the two bytes of the header (10th and 11th) that are related to the TV system don't seem to work properly with Nestopia.

If I change the 10th byte to '01' (bit 0 is supposedly the PAL/NTSC flag) then Nestopia thinks the ROM is corrupt and won't load it.

If I change the two bits (0 -1) of the 11th byte by setting bit 1, which is also supposed to be related to PAL/NSTC, nothing happens.

Does anyone know if there's a way to force Nestopia to load a ROM as PAL? For the hell of it I tried adding '(E)' to the filename to see if I could trick it but no...

I'm sure I've had this working before.

Does changing Options -> Preferences -> Favoured System -> NES PAL, then loading the ROM, have any effect?

Hmmm, that's yet another option that has been left out of the OS X version.

Time to make it Richard Bannister's problem? :-)

I'm not sure Nestopia supports the NES 2.0 extension though; as I understand it, that was invented after-the-fact. I would have to go dig through the file parser though.

I've tried before on other issues but he tends to be (for me anyway) unresponsive.

I've even tried trawling the code myself but, frankly, life is too short
