Roll-chan 4Description

Don’t think this is gonna be a 100% Gold Remake, it’ll have its differences. Extra battles (some’ll be optionals, tough but rewarding), Hoenn Pokemon (in every area, and hard to find) New areas, Remapped some dungeons (so your old guides wont work) , Extra recurring characters (some’ll hate you, some’ll help you)

Note that the hack is incomplete but feel free to enjoy the hack as-is.

Hacked by Zynk Oxhyde



Date Released:


v1.0 December 17, 2014; In commemoration of Rockman/Mega Man 27th Anniversary and beyond! Yay! XD




This is a player sprite hack of Rockman 4/Mega Man IV for the NES!

This hack changes Rock's player sprites into his sister Roll!

There are currently 2 types of patches:

* Classic Roll

* Rockman/Mega Man 8 Roll




In the year 20XX, after the death of Dr. Wily, peace was restored but only for a short time because

a new menace have emerged in the guise of the mysterious Dr. Cossack who threatens the world.

But his true plan is to eliminate Roll by sending off his very own Robot Masters against her. 

But what is Dr. Cossack's true motives? Roll must make the initiative and defeat the Robots Masters 

first before they get her and get to Dr. Cossack himself to answer!

With this new challenge, Roll doesn't fall short against new powerful enemies as she is equipped with a 

new weapon - the New Roll Buster, a powerful charged shot. Fighting with her is her trusted robot cat, Tango

the transforming kitty; and a new support unit, Eddie the walking canister!

How to use patch to unaltered ROM:


* Use ROLLCHAN4-JP.ips on Rockman 4 (J) ROM

* Use ROLLCHAN4-US.ips on Mega Man IV (U) ROM


How to patch on hacked Rockman 4/Mega Man IV ROM:


* Can be patched in any order. Just bear in mind that patch (J)/(U) to corresponding (J)/(U) hacks.

* May cancel some changes in extensive hacks. RM:MI tested to work normally, practically playable & the hack beatable.


Using Roll on other hack projects:


Zynk doesn't mind others using Roll's sprites on their own level hacks; although giving him credit would suffice ::)
