An obscure, if decent little shmup by Athena Co.

Elementary, my dear Cactus.
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

The menu of testing.

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
44BD-A40D
DDBD-A46D
6DBD-A4AD
DFBD-A7DD
00930922
00930A00
00930B80
00930C01

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