Another game similar to ours Zaider – Battle of Peguss (超戦士ザイダーバトルオブペガス). You can walk out of the ship and walk in somewhere. I don’t know details. There is no walkthrough around. The game is on MSX 1986. Ability to walk inside buildings seems interesting. I read that weapon(s?) can be upgraded. The terrible scrolling is not in this game only. It is quite common for MSX games back then.
Also on nicovideo I found probably a remix of the title theme. Sounds nice so I adding it.
