oh yeah, there is this new nvram issue that is causing lots of troubles. can you try deleting the nvram\mbombrd.nv then make a new recording (doesn't have to be a good one, just a test one that gets passed at least one round.) and maybe that might be the problem...(posted 9340 days ago)from what i've seen different platforms of mame with the same mame version make different nvram files, and also different runs may update nvram files, so it's safest to delete the nvram\GAMENAME.nv before recording anything mame36 or after.
believe me even though i'd love to go to italy!, i don't need to to know your recordings are acurate. you've already got a bunch of recordings that work for you. It's this new mame version that is being a pain: disalowing most from seeing the recordings you record (which is what this site is about.)
