Oh dear, I do believe I have the vapors. This page contains content that is not safe for work or other locations with the potential for personal embarrassment. Such as: About four pixels' worth of dystopian Amazonian future nipple.

Strider Hiryu is here to overthrow an evil dictatorship and defeat Palpatine, mostly by swinging his sword very fast at anything that moves.

Prerelease Info

Tile Viewer

There's code at 0x71E10 (offset is for the strider set in MAME) that would enable an extra option, "CHARACTER", on the test menu if input 0x04 was held down before the menu popped up. Unfortunately, 0x04 corresponds to 1P Coin, and both 1P and 2P Coin inputs are disabled in the test menu. Put the following code in MAME's strider.xml cheat file to change 1P Coin to 1P Start:

  <cheat desc="Fix Full Test Menu Access">
    <script state="run">
      <action>maincpu.mw@071E16=0040</action>
    </script>
    <script state="off">
      <action>maincpu.mw@071E16=0004</action>
    </script>
  </cheat>

From there, just choose "CHARACTER" to access the tile viewer menu. Pick "OBJECT" for sprites, "SCROLL1" for the game's font, "SCROLL2" for the foreground tiles, and "SCROLL3" for background tiles.

Controls:

• Up: Scroll down.
• Down: Scroll up.
• Left / Right: Scroll through available palettes.
• Button 1: Toggle vertical flipping.
• Button 2: Toggle horizontal flipping.
• 1P Start: Toggle between a simple and complex tile display.
• 2P Start: Loads the next level's palette group.

Unused Graphics

Uncensored	Censored (in-game)

The Amazon enemies have their left breasts exposed in the stored graphics. This is covered in the actual game with a separately-stored green leaf sprite. Add the code in strider.xml to check it out.

What appears to be graphics for a test tileset. Includes every possible surface type and hexadecimal 16×16 blocks.

32×32 tiles for a logo of "The Falcon", the name with which the game was first revealed in western gaming magazines. In an interview with game planner Kouichi "Isuke" Yotsui, he explained that this title was initially chosen because Capcom USA wasn't convinced with the Strider name until they changed their minds later.

Put the following code in the striderj.xml cheat file to replace the normal title screen logo with this one:

<cheat desc="Restore old title screen">
    <script state="on">

Unused Sounds

ID	Track Name	Sound
17	3ST ST3

Seems to be an alternate version of the intro tune for Stage 4.

ID	Track Name	Purpose?
1E	4ST DEMO	Stage 3 cutscene track.
21	ENDING	Ending credits track.
23	TIMEOVER	Music for when time is running out.

These music tracks do not exist in the ROM, but have unique IDs and track names in the Output Test. They all point to Track 00, the Stage 1-1 music. A Stage 3 cutscene track and an ending credits track were eventually recorded for the Sega Genesis and Sharp X68000 ports. A time running out song was recorded for the Sharp X68000. The sharp X68000 would get an arrangement of the Genesis credits song for the Name Entry screen.

ID	Sound
82
83
84
85

Various utterances and grunts from Hiryu that aren't used in any version of the game. Curiously the 83 is the version used in the Japanese version of the Genesis port.

Unused Text

Two pieces of text giving the full names of the game's programmers can be found in the game memory.

The first is at 0x0039AA:

Porgrammed by Yamauchi & Komatsu

The second starts at 0x004542:

Programing by Tae Komatsu Toshihiro Yamauchi Toshihiko Miki

In the credits, these three are listed as "TAE 250R", "T+MARUCHI", and "MIKKUN" respectively.

Text exists for a Scroll Test (like the one found in Ghouls 'n Ghosts) but there's no known way to access it.

Text starts at 0x00407D in memory.

SCROLL TEST 1. SCROLL 2. MAPPING ENTER A SHOT EXIT C SHOT

MAPPING 1. SCROLL1 2. SCROLL2 3. SCROLL3 ENTER A SHOT EXIT C SHOT

SELECT STAGE 1. STAGE1 2. STAGE2 3. STAGE3 4. STAGE4 5. STAGE5 ENTER A SHOT

Regional Differences

ID	Sound
81

In the Japanese sets, Hiryu makes a "Hah!" sound every time he swings his sword. This sound is not used in US sets.

Revisional Differences

ID	Track Name	Purpose
18	4ST BGM1	The first section of Stage 3.
19	4ST BGM2	Second section of Stage 3 - Inside the Ballog.
1A	4ST BIG	The final section of Stage 3.
1B	5ST BGM1	The first section of Stage 5 - Outside of Third Moon.
1C	5ST BGM1	The second section of Stage 5 - Inside Third Moon.
1D	5ST BIG	Music for the final boss.
1F	5ST DEMO	Intro to Stage 5.
20	CLEAR	Stage 5 Clear music.
22	RANKING	High Score theme.

The earliest Japanese and US sets are missing many pieces of music, with Stage 1-1's music used in their place. This mostly affects the 3rd and 5th stages.
