@mrmadcatz I think you got your info here - from @barbudreadmon. The configuration for this game in the hiscore.dat file is wrong - that's why saving the hiscore doesn't work.
Same situation is present in MAME, so it looks like saving it won't work until someone adds a proper hiscore.dat entry for the game. The hiscore.dat file instructs the emulator how to save the high scores for the game, if there's no entry for the game or if the entry is not correct, no emulator will be able to save high scores.
