J'ai regardé plus avant et j'avoue ne pas comprendre.
Higan v104 et v105 utilise la même base de données Super Famicom.bml datant du 26/10/2016. Elle a été mis à jour dans la v106 mais aucun changement au sujet de Mega Man X2 et X3.
Pour la cx4.data.rom, on a bien:

Quant à Icarus, le seul changement reporté dans les release notes et l'ajout d'une icône dédiée, rien d'autre. Entre v105 et v106, icarus.exe est exactement le même fichier.

Au regard de la documentation à laquelle j'ai eu accès (je suis même allé regarder un peu dans la source d'Icarus au cas où je verrai un truc particulier sur la ROM en elle même
https://gitlab.com/higan/higan/blob/...er-famicom.cpp ), je n'ai aucune explication. Une question à poser directement sur le forum de byuu je pense dans la section Icarus.
