An obscure, if decent little shmup by Athena Co.

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: There are unused enemy graphics. Artist interview in page 187 of book "ゲーム職人 ゲーム文化を支えた37人の証言": "敵キャラの種類に関しては、実はROMに半分眠っているものがあるんです。プログラマーが間にあわなくて（笑）、使ってないんです。" "Half of enemy characters slept in the ROM. Because Programmer couldn't work in time, so It is unused."

TEST MODE

A debug menu called TEST MODE begins at SNES address $018000. There is no JSL $018000 in the programming to reach it, however. A string of nine EA NOP bytes located at SNES address $008076-00807E possibly contained the original entry point at one time.

Use these game enhancer codes to access it:

Game Genie	Pro Action Replay

Activate the codes at bootup, and wait for the intro logos to pass without pressing any buttons.
