To unlock the other two Navigators' weapon, clear any four stages (can be done with previously cleared stages) with the Navigator you are trying to unlock. Let's Play Mega Man X8 - 100% Completion Run & New. For that reason create a file of 30 ffs from the start. Megaman X8 'Absolute 100%' X8, according to the DF list on the SDA Knowledge Base, should be encoded with D1 F1 3D. If you completed the game on Normal or Hard and load the clear game file, the weapon for Navigator you used the most in your previous round becomes available in the R&D Lab. Along with unlocking X's, Zero's, Axl's secret armor, the Navigators - Alia, Layer, Palette - can be unlocked as playable characters.
