Another ROM hack of Mega Man 2 by Infidelity, this version, titled "Mega Man Ultra," likely presents significant alterations to the original game's content. The nature of the changes would require more specific details to elaborate.  However, expect variations in enemy behavior, level layouts, boss battles, and potentially even the inclusion of entirely new content. This demonstrates the enduring appeal of Mega Man 2 and the passion of the ROM hacking community.  The base game's mechanics remain largely intact, but the content is drastically changed by the hack.
