(Version 10.13) I've been having similar problems with Gorf..i have beaten my old score a few times and launchbox high scores isn't recognizing i have done so. (no new scores found to upload)..i did try deleting the .hi and nvram before the next attempt but unfortunately it still didn't upload (no new scores found to upload). (using mame .217, mame.217 romset, applicable hiscore.dat). I've even tried different versions of the same game and on my other PC. Log attached.
Worked perfectly well the first time (version 10.12) i played and submitted the high score but seems to have trouble on any further subsequent high score attempts. I really want to get it working as i think it's the best update launchbox has had.
I really appreciate the hard work done so far on this feature!
