Apologizes if this is the wrong location for this. I have previously had no problems loading up Sega Master System roms on older versions of Bizhawk (specifically 1.7.0 and 1.13.0). However any attempt to do so on any build from 2.0 up, including the most recent that I know of 2.2.1, I am told I am missing the relevant firmware files. Looking at the firmwares menus in both 2.2.1 and 1.13.0, with my limited knowledge, they look the same. And I assume if I have them for one I have them for the other. I can play other consoles ROMs on 2.2.1 seemingly without issue, testing both genesis and GBA games. The ROM I am currently trying to open is Sonic Chaos, though I've had issues with other Sonic sms roms in the past too. Am I missing something obvious that I'm doing wrong? Any help would be greatly appreciated. Thanks.

Tested sonic Chaos just now. Works fine with: Active Firmwares: Export : C315672807D8DDB8D91443729405C766DD95CAE7 Check your region settings and make it's on 'auto' or 'export.'

Ok thanks. I do indeed have that firmware... and this has to be a very basic question but I've trawled through the menus a few times now and the region settings escape me. I thought I recalled doing it before, though I may be think thinking of doing it back in the day in Dega. Mind spelling it out to me?

Sure, it's under the 'SMS' header in the menues. Ah, I think I see the problem, you probably can't even get to that since it's not letting you load the ROM. (It's probably looking for the JPN BIOS and not finding it.) Try deleting your config.ini file. This will reset the core back to it's default which is 'export.' Then you should be able to load the game up. I should fix that.

Ah I see. Yeah, I can see such a header in the menus when I load up genesis or GBA roms. But yeah, can't even get that far with SMS as you suggest. Unfortunately deleting config.ini has not seemed to have any effect?

Hmmm, Try getting a fresh install of 2.2.1. Then put ONLY the USA/Europe BIOS in the firmware folder. Then try loading the ROM. I tried this just now and it worked without issue. If this still doesn't work then I'm pretty stumped.
