Ninja Gaiden: Ninja Gaiden - Deadly Duel Edition

UPDATE v 1'2: there is now two versions of the final boss.

This new hack is based on my old "Ninja Gaiden - Updated" hack.

The main novelty is the integration of a modified AI for the bosses, in order to make the fights more interesting and... more deadly.

On the contrary, the difficulty of the levels has been slightly reduced.

The bug that sent the ninja back to the start of level 6 after losing to one of the last bosses has also been fixed.

Thank you very much to:
- never-obsolete for his Ninjax editor
- Ninja Gaiden Rom Map in Data Crystal
- Maël Hörz for his HxD hex editor
- and of course the Bouix family!
