Drakkhen is a really weird RPG in which you walk around an overworld in first-person view, explore dungeons in a side view, and monsters yell "Ecch!" a lot. Just don't fall into the water.

Unused Debug Display

There is an unused debug flag at $7E9978 in the SNES RAM. Set it to $01 to activate the debug display. There are two numbers will be displayed at the top-left corner of the screen, representing some parameters of first two characters in the party.

Additionally, set $7E997A to $01 to display the ending easter guitar sprites depending on a current state of the game. Note, there are two more guitars than in the regular ending (see info below). They may be revealed by entering the first player's name as "DRAKKHEN".

Regular Guitars

There is an "guitar easter egg" in the credits which is activated depending on how many player characters are dead when entering the ending. Up to 4 guitars may be displayed based on how many players left alive at the end of the game.

Punk Head

Additionally, there is an extra object of the Punk Head at the left side of the screen appear sometimes. There is no strict condition to make this sprite appear. It appears if random number generator of the game generates the number where lower 5 bits are 0. The random number generator depends on H/V PPU counters, position of the player on the map, direction on the map, frame counter.

Unused Spells

Many spells from the PC version are still in the game in an unfinished state.

7EA133xx - "Fight" setting for second character

Values for xx (note that entries in italics can be learned in-game but can't normally be cast in battle):

  • 05 - Cure: Seems to work normally.
  • 06 - Light: Works, but the screen doesn't light up until you switch menus or characters, and the light seems to last forever.
  • 09 - Language: Works, but doesn't do anything noticeable. Overrides Light.
  • 0B - Unlock: Makes doors open before the graphics even load if an enemy is in there.
  • 0E - (blank): Unknown effect. Probably supposed to be Lock.
  • 11 - Speed: Nonfunctional.
  • 12 - Isolation: Nonfunctional. She never casts it in battle. (Not yet tested outside of battle.)
  • 13 - (blank): Unknown effect. Probably supposed to be Restore from the PC version, but it's still unknown what that does, either.
  • 15 - Resurrection: Bizarre effect where the caster is sent back to her party (dungeons) and can't leave the room. Outside, no visible effect. Nobody gets revived in any case.
  • 16 - Blindness: Nonfunctional. Spell is never cast.
  • 17 - Teleportation: Works, but anybody in the entrance room can't move afterwards. The only way out is the Door icon.
  • 18 - Dragon power: Unknown effect. The character using this spell cannot move.

Unused Equipment

To do:
even more stuff; such as a Water item and Spell Book from the PC versions

Unused Monster


A "trap door" monster from the PC version seems to have been worked on, but ultimately scrapped. He is in a very unfinished state. Use the code 7E983807 to see him in action; you might have to enter the character menu first.

Hazhulkha Animation

Drakkhen snes hazhulkha.gif

Normally Hazhulkha does not move when you meet her in the SNES version, but if you use the code 7E983836, she will animate. Note that she did animate in the PC version.

Unused Graphics

Meow!Drakkhen snes cat anim.gif

Two frames of a running calico cat are stored with Drakkhen's overworld graphics. The graphics change for each of the game's four overworld regions, but the cat stays the same. This indicates it's probably just filler.'s winking at me.

A happy face can be found stored at the end of the moon phase graphics. It is also most likely to be memory filler.

Buckets of fun!

This bucket appears with the menu graphics in the ROM. In the PC version of Drakkhen, this bucket appeared on the inventory screen and when you wanted to drop items, you'd drag and drop them into it. In the SNES version, there is a command to drop items but it is text only. The bucket sprite is not used.

Older magic meters

These are loaded into RAM when the game is loaded, then overwritten with the sword/staff graphics. They appear to be older versions of the battle/magic meters.

Regional Differences

The Anak shrines had a cross along the top in the PC and Japanese SNES versions.
