Improvement Game Boy Color

Penta Dragon DX

ペンタドラゴン

A Game Boy Color conversion of the Japanese Game Boy action game Penta Dragon that adds full, scene-aware color while leaving the gameplay untouched.

What it does

Penta Dragon DX turns the monochrome 1992 Game Boy release into a Game Boy Color game. Backgrounds, sprites, pickups, rotating hazards, the title screen, the story scenes and each boss get their own palettes, chosen to match the scene on screen. Movement, music, maps, cutscenes, the title demo and the boss fights are kept exactly as they were, and the text stays in the original Japanese.

Status

This is a pre-release: version 3.01 RC5, published on 2026-07-31 as a release candidate for the author's livestream tuning. It colors every Stage 1 pickup by type (health, rare items, cures, defense and attack items each get a color) and fixes a white-screen freeze when starting a game after the attract demo. The author is still testing on real hardware and tuning palettes before the first final release, so expect updates.

Playing it

The patch is applied to your own Japanese cartridge dump of Penta Dragon, following the instructions on the project's GitHub page. Releases contain only the patch. The project is developed with AI assistance, as its repository states.
