Global Champion is Taito's first proper 2D one-on-one fighting game (excluding Dino Rex) which gained infamy for its unforgivingly unbeatable final boss.

A sequel named Dan-Ku-Ga was never released (until the release of the Egret II Mini system in 2022) despite having an almost-perfect prototype version (eventually leaked) already made.

"I am a perfect soldier!"

Kumagaya Easter Egg

GlobalChampKumagaya.png
Like most of the titles they developed, Taito Kumagaya Laboratory snuck their logo in the game, though the method to access it in this title is more esoteric than usual and it only works on the JP set:

  • Before the game boots, hold 1P Start + 2P Start + 1P Up + 2P Down until the "Wait a moment" screen appears.
  • Then, during any gameplay demo, press 1P Button 1 three times.

The picture alternates between the logo and game credits for Takeshi Kobori, Hiroshi Aoki, and Yuji Sakamoto.

Debug Functions

Crash Handler

GlobalChampion-CrashHandler.png
This game has a basic exception handler for the standard set of exception vectors. One method to trigger this handler is to put one of the following MAME codes in MAME's gblchamp.xml cheat file to play as General, start a new game, and not skip the VS screen animations:

 <cheat desc="P1 Play as General">
   <script state="run">
     <action>maincpu.pb@40B321= B</action>
     <action>maincpu.pb@41454D= B</action>
   </script>
 </cheat>
<cheat desc="P2 Play as General">
   <script state="run">
     <action>maincpu.pb@40B521= B</action>
     <action>maincpu.pb@41454F= B</action>
   </script>
 </cheat>

Expanded Input Test

Normal Expanded
GlobalChampInputTest.png GlobalChampF3SwitchTest.png

Entering the Taito Code (1P Start (×3), Service Coin, 1P Start) on the switch test will greatly expand the test to include all of the standard F3 system inputs. However, Buttons 4, 5, and 6 for each player are excluded from this test, limiting its usefulness.

Debug Menu

NOTE: For both this and all remaining debug functions that modify the game ROM, put the following code in MAME's gblchamp.xml. This will bypass the game's ROM checking subroutines and allow the game to boot properly:

  <cheat desc="Ignore Checksum">
    <script state="run">
      <action>maincpu.mw@0011DC=0x0002</action>
    </script>
    <script state="off">
      <action>maincpu.mw@0011DC=0x00DC</action>
    </script>
  </cheat>

Global Champions is supposed to feature the Taito Code:

  • While the game boots up, hold the Service Coin button until the "SERVICE SWITCH ERROR" message pops up on the screen.
  • Then, press 1P Start (x3), Service Coin, 1P Start.

...but the subroutine to do this is orphaned in the retail version. Put the following code in gblchamp.xml to put the input check back in:

  <cheat desc="Enable Debug Menu Check">
    <script state="run">
      <action>maincpu.md@00A4DA=0x4EF90000</action>
      <action>maincpu.mw@00A4DE=0xA4F6</action>
    </script>
    <script state="off">
      <action>maincpu.md@00A4DA=0x303C00B4</action>
      <action>maincpu.mw@00A4DE=0x3F3C</action>
    </script>
  </cheat>

GlobalChampDebugMenu.png
After successfully entering the code, a debug menu should appear. "Normal Start" will, just as the option suggests, start a normal game, but the other options (besides "DUMMY", which does nothing) are more interesting.

Debug Start

Start the game in debug mode with 9 credits. Debug mode has the following features:

  • All export warning screens are skipped.

GlobalChampDebugMatch1.png

  • Starting a new game will load a debug character selection screen.

Controls

  • 1P Up/Down / 2P Up/Down: Selects between fighters. This includes boss characters!
  • 1P Left/Right / 2P Left/Right: Toggles whether or not that fighter is controlled by the CPU. CPU vs CPU matches are possible.
  • 1P Start / 2P Start: Adjusts the map number.
  • 1P Button 3 / 2P Button 3: Swaps between the default and alternate palettes for that fighter. Does nothing for boss characters.
Any other action button will start the match.

GlobalChampDebugMatch2.png

  • The game will display the distance between the two fighters at the top, and other pertinent information for both fighters (Like the amount of damage taken for the current hit, the player's action number, status bits, X and Y positions, etc.) at the bottom.
  • The round timer is disabled.
  • After either player wins the match, the game returns to the debug character select screen.

Character Test

Animation Test

Put the following code in MAME's gblchamp.xml cheat file and enable it to replace the first "DUMMY" option in the debug menu with an animation editor:

  <cheat desc="Anim Test">
    <script state="run">
      <action>maincpu.mw@051A54=0x1972</action>
      <action>maincpu.md@051AEC=0x0004435C</action>
    </script>
    <script state="off">
      <action>maincpu.mw@051A54=0x1ACC</action>
      <action>maincpu.md@051AEC=0x00000000</action>
    </script>
  </cheat>

This menu lets the user toggle hit and hurtboxes, the crosshatch pattern in the background, and "2Disp", which adds a non-animated sprite to the screen.
  • 1P Start (Held) + 1P Up/Down: Selects option in MODE menu.
  • 1P Start (Held) + 1P Left/Right: Toggles option MODE menu.

Running Debug Menu

Put this code in MAME's gblchamp.xml cheat file to enable a Tilt-triggered debug menu.

  <cheat desc="Tilt Debug Menu">
    <script state="run">
      <action>maincpu.md@000510=0x4EB9001F</action>
      <action>maincpu.md@000514=0xF0004E71</action>
      <action>maincpu.md@0009E4=0x4EB81D04</action>
      <action>maincpu.mw@0009E8=0x4E75</action>
      <action>maincpu.md@1FF000=0x4EB823CC</action>
      <action>maincpu.mw@1FF004=0x4E75</action>
    </script>
    <script state="off">
      <action>maincpu.md@000510=0x0C80001F</action>
      <action>maincpu.md@000514=0xFF8E642E</action>
      <action>maincpu.md@0009E4=0x4E4A007C</action>
      <action>maincpu.mw@0009E8=0x0700</action>
      <action>maincpu.md@1FF000=0xFFFFFFFF</action>
      <action>maincpu.mw@1FF004=0xFFFF</action>
    </script>
  </cheat>
  <cheat desc="Tilt Debug Fix">
    <script state="run">
      <action>maincpu.md@000510=0x4EB9001F</action>
      <action>maincpu.md@000514=0xF0004E71</action>
      <action>maincpu.md@1FF000=0x4EB823CC</action>
      <action>maincpu.mw@1FF004=0x4E75</action>
    </script>
    <script state="off">
      <action>maincpu.md@000510=0x0C80001F</action>
      <action>maincpu.md@000514=0xFF8E642E</action>
      <action>maincpu.md@1FF000=0xFFFFFFFF</action>
      <action>maincpu.mw@1FF004=0xFFFF</action>
    </script>
  </cheat>

GlobalChampRunningDebug.png
The game pauses when the menu pops up. "Cancel" exits the menu and "Reset" resets the game. As for the other options...

Process Meter

GlobalChampProcessMeter.png
This normally does nothing, as the subroutine that controls this feature isn't normally called during play. With the tilt debug fix, this displays a CPU meter below the second player's life bar.

Task Status

GlobalChampTaskStatus.png
Like the process meter option, this normally does nothing. With the fix, this displays the internal task IDs for every currently-loaded task. Tasks labeled "E" are currently running, while tasks labeled "W" are waiting for other tasks to complete.

Hit Mode

GlobalChampHitMode2.png GlobalChampHitMode.png
Use 1P Joystick and then press any button to toggle displays for player hitboxes ("ATK", displayed in red), hurtboxes ("HIT", displayed in yellow), both, or neither.

Speed Change

Use 1P Joystick and then press any action button to choose between the following game speeds: 0.5x, 1x, 1.25x, 1.5x, 1.75x, 2x, and 4x. The 0.5x option doesn't seem to work.

Color Edit

GlobalChampColorEdit1.png
Allows the user to edit the game's palettes on the fly.

Controls

  • 1P Up/Down: Adjusts the currently selected RGB color gauge.
  • 1P Left/Right: Selects between R, G, and B gauges for the selected color.
  • 1P Button 1 / Button 2: Selects between colors in the current palette.

GlobalChampColorEdit2.png

  • 1P Button 3: Switches the editor between the top or bottom of the screen.

GlobalChampColorEdit3.png

  • 1P Start: Hides the editor and disables controls (except 1P Start).
  • 2P Up/Down: Adjusts palette number by 02.
  • 2P Left/Right: Adjusts palette number by 10.

To exit this editor, bring the running debug menu back up and then select "Color Edit" again.

Regional Differences

Global Champion and the World version of Kaiser Knuckle all share these changes from the Japanese version of Kaiser Knuckle.

Character Select Screen

Kaiser Knuckle (Japan) Global Champion / Kaiser Knuckle (World)
Globalchcharskazuyagc.png Globalchcharskazuykk.png
Globalchcharslihualizagb.png Globalchcharslihualizakk.png

Kazuya, Lihua and Liza had their faces redrawn for outside of Japan.

Audio

JP INT
Kazuya Intro
Kazuya Win 1
Kazuya Win 2
Lihua Intro
Jim McCoy Intro

A few of the more obviously "foreign" voice clips were replaced in non-Japanese sets, mostly with grunts. Jim McCoy's intro line was replaced with Barts' "Hey, come on, kids!" voice clip.

Medic

Globalchmedic.png
At the end of a match in the Japanese version of Kaiser Knuckle, a medic will rush on-screen to check the defeated character, offering a diagnosis as part of the end-of-fight score tally (a translated list of those diagnoses is available at Mizuumi Wiki. All of this was removed from international versions.

Test Mode

Kaiser Knuckle (Japan) Kaiser Knuckle (World) Global Champion
Globalchtestmodekk.png Globalchtestmodegb.png Globalchtestmodeus.png

The Test Mode in each version has different options. Both the World version of Kaiser Knuckle and Global Champion add the following options to the ones seen in the Japanese Kaiser Knuckle:
GlobalChampBlood.png

  • Blood Mode: Add blood effects to every hit.
  • Game Speed: Alter the speed of the game (as opposed to the timer).
  • Control: Switch between 6 Trigger and 5 Trigger- 6 Trigger is the same as the Japanese Kaiser Knuckle, but 5 Trigger replaces Strong Punch and Kick with Block buttons. You must hold this button to block instead of holding back as in 6 Trigger mode. This changes several other mechanics too- you now have to press Light and Medium attacks together for Strong attacks, and the universal dive attacks cannot be performed.
  • BGM: Toggle the background music on or off.

Global Champion also adds one more:

  • Continue: Set whether more credits are needed to continue or if it costs the same as a normal game.

Other Changes

JP INT
GlobalChampPowerGaugeJP.png GlobalChampPowerGaugeINT.png
  • The super meter is the CRUSH meter in Japan, and the POWER meter elsewhere.
  • The Japanese version contains text in the attract mode intro and after General is defeated at the end of the game. All this was omitted from international versions.

GlobalChampFighterIntro.png GlobalChampAreYouReady.png

  • The character story intros that appear after selecting your character and your first opponent are not in the international versions.
