Theme of Inn and Home
As the title suggests, Theme of Inn and Home (宿屋&家のテーマ) plays when you're in the Worzen family's home or in the dungeon's various inns. The song is bright and cheerful, a welcome tune after a long journey through the dungeon. The NES and MSX versions are nearly identical in sound.
The title is translated from Japanese on the official MSX soundtrack.
Legacy of the Wizard (NES)
Theme of Inn and Home features a less chippy sound on the NES. The drum beat is more believable and the overall tune is crisper. The song is track 7 in the NSF file and plays on the RP2A03.
Dragon Slayer IV: Drasle Family (MSX)
The song for the MSX is a bit more chippy sounding, and the percussion is less believable. The song is track 7 in the KSS file and is played on the AY-3-8910 on the MSX and the identical-sounding YM2149 on the MSX2.
