The NES Dragon's Lair is a rather underwhelming platformer based on Don Bluth's famous Laserdisc game.

Miscellaneous tidbits that are interesting enough to point out here.
Notes

Source Code

While the US version uses a 128KB ROM, the Japanese and European ones use 256KB ROMs. As a result, the latter two have a lot of unused space filled with garbage, leftovers from MS-DOS executables, and more.

Still, there's a lot of source code within said garbage.

Combined Source

The Japanese and European versions contain different portions of their source code which can be compiled into one huge file, covering almost all of program banks 30-39. There are some differences between the two versions, and it appears the Japanese one was done earlier.

Regional Differences

Framerate improvements aside, several notable differences exist between the US/Japanese and European versions of the game.

Splash Screens

These screens were added to the European version and appear as you enter each stage. Oddly, the dungeon does not have one. The splash screen for the Entrance Hall depicts a boss that was added for this version, detailed below.

Entrance Hall Boss

US/Japan Europe

A giant snake boss was added to the European version, which replaces the multiple snake enemies at the end of the Entrance Hall. The boss shoots projectiles either directly at you or towards the floor as you try to hit it in the face.

Spider

US/Japan Europe

For some reason, this spider enemy only appears in the European version. Touching it is an instant kill. Only seen in the Entrance Hall. They replace some of the snake enemies from the US version.

Flying Insects

In Entrance Hall, Bats fly out of the openings in the US version, while the European version uses flying insects of some sort.

Death Animation

Flat Dirk.

When Dirk gets flattened in the European and Japanese versions, you get a unique animation of him getting stuffed inside his helmet with only his feet visible and walking around for a bit. In the US version, you get the usual skeleton death for everything.

The Elevator Shaft

The European version was made a bit harder here with added projectiles flying around the elevator shaft. Touching one is instant death.

Music

The music plays faster in the Japanese version. Also, as with most PAL games, the music plays a half-step/semitone flat of what the USA version sounds like. Some songs in the European version play faster compared to the USA version, while other songs play slower.

Ending Theme

A few notes were changed in the game's ending theme in the Japanese and European versions at about 0:24 (US/European version), 0:20 (JP version).

US Japan

Here are the notes from that bar written in MML for easier understanding,

US version:

E4+q. D4+8 D4+h. A3+q B3+q C4+q D4+w 

European/Japanese version:

E4+q. D4+8 D4+h. A3+8 B3+8 C4+q D4+q D+w

High Scores

There were a couple minor tweaks to the high scores between the US, European, and Japanese versions.

US European Japanese
SINGE SINGE SINGE
MTIME MTIME MTIME
CSG SBIM SBIM
SBIM ELITE EPIC
DAPH DAPH DAPH
TOM TOM TOM
DICK DICK DICK
HARRY HARRY HARRY
  • The place for SBIM was swapped from 3rd place in the US version to 4th place in the European and Japanese versions.
  • The 3rd (U)/4th (E/J) scores represent the publishers for their respective companies; CSG, Elite, and Epic.

Speed Differences

The Japanese and European version uses an MMC3 mapper. As a result, the game is more responsive compared to the US version which uses an UNROM mapper.

Controls

The European version uses "B" button to jump while the US and the Japanese versions use the "Up" button.
