For the bootleg you can do the required name registration. It then returns to the title screen. It is AFTER trying to start a game on the entered file that the game freezes (with a tone) on the "AOSAME JOH" first castle intertitle screen. The one thing I can add is on the sound issue. At the time this bug report was made MAME lacked emulation for the FDS sound channels. As nazomura isn't running I ran nazomfds in the debugger. It writes the FDS sound registers on the title screen and never writes the regular APU sound registers. From real hardware footage (www.youtube.com/watch?v=fq-566ANsFw&t=95s) we can see the only sounds in the FDS original are the lightning. It's safe to assume the FDS version only uses the FDS sound channels to generate the lightning sounds, so if the game gets fixed the lightning sound should be there. For nazomfds there will never be a lightning sound. It's the norm among the FDS-to-cart bootleg conversions to have missing sounds and music voices if they used the FDS sound hardware.
