First I’d like to start off by saying that I hear the crickets too. This game is older than dirt, older than Chief Keef and Justin Beiber. But Let me say that this game was good for its time. This game is so old that I’m having trouble finding a move list for this game as there are some mechanics in the game unclear to me.
For the most part, it plays like SF2 but with the original Mobile Suit Gundam characters. It is on MAME and Arcades should you ever find the time to play it( or make a time machine to find that one arcade cabinet in Japan to play it). I6t has a nice roster of characters and nice presentation to its arcade mode sequence as it has small cutscenes and stuff to it. Not a shabby poverty game if you ask me.

EDIT: Here is a movelist from a jp site. Make sure you have jp translation on:

I gave up on trying to find an english movelist so I copy-pasted the kanji in google and voila.
Off-topic: This link has some footnotes on other older games like Asura Buster and Dragoon Might, but when its translated the grammar is mangled. Use what you can
