Rockman No Constancy

Hack of Mega Man 2


Rockman No Constancy is a hack of the Rockman 2 game. (Not Megaman 2) This is a well done hack made by IKA (A Japanese ROM hacker), all of the eight robot masters levels seem to be completed and the Dr. Wily stages altered (Finished?). This hack includes a completely new soundtrack, new graphics, altered bosses/weapons, and completely new level layouts. The difficulty level has been ramped up, but not as much as in other Mega Man 2 hacks (at least with the “normal” difficulty IPS patch). The “hard” version of the patch makes the game just about impossible because enemies can continue to hit your character without any “reflex time”. This makes it so once you come in contact with a boss (or one of his projectiles) you have pretty much lost the fight.

One of the best!

Reviewed By: RRThielNC on 21 Oct 2014

Rockman No Constancy is considered by many people to be one of the best, if not THE best Rockman hack of all time. Those are pretty big claims. And, while I wouldn’t call it the absolute greatest hack out there, I can wholeheartedly say that it’s right up there as one of the best! RNC is a hack that changes the level design, music, tiles, weapons, and boss/enemy A.I, and almost everything in this hack is done very well!

First off, this hack looks great. The visually pleasing color palettes, mixed with the very top-notch sprite quality make this hack an absolute treat to look at. Many, if not all of the levels from this hack are references to other games. For example, Air Man Stage is based off the Bubbly Clouds level from Kirby’s Dream Land, Flash Man’s level is based off a level from Yoshi’s Island, and Wily Stage 4 is based off a level from MegaMari.

The music in this hack is also very well done. While I didn’t recognize any tracks at first, I still enjoyed them greatly. Not only are the songs nicely done, but they also fit their stages very well, which is pretty important for having a good soundtrack. I’m pretty sure there’s an NSF file available for download somewhere on the internet, so if you have an NSF player, go crazy with that.

The boss/enemy A.I in this hack, while sometimes frustrating, is very impressive and cool. While not all enemies have new patterns, the ones that do are pretty nice. The bosses in this game are impressive, but they can be very tough at times. Most of the bosses are very agile and can hit pretty hard. The final boss, for example, can hit like a bulldozer if you run into him. But that’s beside the point. The A.I is very good.

Level design is the flavor of the day with a lot of these hacks, and that’s because it’s damned important. I don’t care how pretty your hack looks, how impressive your A.I is, or how good your music is. If you have bad level design, I will deduct points. Luckily, RNC passes with flying colors. Each level is very well put together, providing lots of challenge(sometimes a little too much so), fun, and replay value. The best part about it is that it feels really gratifying when you get really good at it after dying over and over, and there’s never a point where I feel dying is the game’s fault.

Overall, I don’t really have anything to complain about with this hack. It looks great, it sounds great, the A.I is great, and the level design is great. While I don’t think I would call it the greatest hack of all time, I certainly think you’s be doing yourself a disservice by not at the very least giving it a try. I give this hack a full recommendation to go play it!
