Yes the floor is missing the "line scroll" on the PCB also so MAME is correct, i will update the mametesters post with an PCB recording so there is no doubt Tecmo system does not seem to be a powerful system?
I noticed it played the music in stereo in MAME... now i must find the pinout for the speaker connector.
Asasega: i always do OSV's when i can (if the game has a soundtest)
