Pretty good hack

Reviewed By: Cupcom5/NGKFlower on 12 May 2020

I came across this hack from a few youtube videos, and just recently I wanted to give it a try myself. So I played it.

If Megaman had a baby with Streets or Rage Mania mode, this would definitely be it. I can tell a lot of love and thought was fleshed out for this game, and I could definitely say Good Work!


  • Use of Megaman X elements like the dash and partner call (X3), it shows that if someone really wanted to, a megaman X hack could be made for the NES, I would like to see that. I’ve been using Quickman a lot in some boss fights, especially against Yoshinoman (don’t know if he is based off an actual person or an OC for the game.)
  • Creative points for Cheatman’s originality, because that is exactly what he does during both fights. My only problem with him is he has too many one-hit kill attacks. -_-
  • Bomberman. What more can I say, it bomberman! I like how his bombs can be used against him, like from his actual games. Him becoming a ghost and fighting Bombeman Black was pretty cool too.
  • Mario stage transition. It was pretty cool how it went from the water stage straight to the boswer castle.
  • Interesting concept of an evil Megaman protagonist, would be cool if Capcom actually did do something like this.
  • Airman is literally air. lol
  • Good to see Kamen Rider make an appearance in a megaman game like this. I got a good laugh and entertainment fighting against him :)
  • Love the whole Yoshi Island boss reference, it’s literally the best thing of the game and what really inspired me to play it. LOVE!!
  • Quickman minigame at the end was fun, I died once. lol


  • It was pretty painful for me fighting against The Blue Bomber himself like this, I got the feels each time. :(
  • As mentioned earlier, though Cheatman is great, I think he has way too many one-hit kill attacks: Cheat Saber, Fireball, when he lands next to player to do a slash attack, plus the instant pit he does. I can possibly understand the cheat saber killing you instantly since that is his specialty, but it’s Cheatman. eh, meh.
  • Mario. This guy… I think him and Cheatman are almost tied in annoyance. Not sure why the axe kills you instantly, I mean it’s not technically a spike. Also he can hop on your head and you can’t get out of it. In other words, Easy KO for him.
  • Some of the Dr.Light stages were ridiculous: the stage that plays Undertale “Megalovania” one with all of the spikes I thought I was about darn near ready to pull my hair out! Bad enough the Rider Joes made it much more difficult to not fall into the pit or drop on the spikes.
  • Airman stage was just a tad confusing with the slippery platforms; are they in the sky or on ice? I am aware that the higher one gets into the sky, the altitude makes it very cold, if that was aimed for here.
  • Dr. Light with his Shotokan/Ansatsuken style, the Hadoken is PRETTY much a one hit kill, the Shoryuken leaves the player with probably one bar of health if you’re lucky.
  • This is very minor, but personally, I think it would’ve been better if the water stage for Mario was the Mushroom Kingdom stage, would’ve made sense to me since it’s an iconic stage like Sonic with Green Hill. Good nonetheless.
  • Cheatman, Rush and Dr. Light all have this rapid attack where they can just keep hitting you with certain attacks ( machine gun fire, Rush tornado if it connects, Dr. Light’s Tatsumaki Senpu Kyaku. It’s kinda repetitive and annoying, when you don’t have any health left to use.

Well that said, I give the game a 4/5, It’s a good hack no doubt, but I believe some things could still be polished. I’ve been using Savestates like crazy in this game, MOSTLY against Cheatman,Yoshinoman,Rush and Dr. Light fights. I would recommend if you love Megaman games (like me, lol) or just looking for a challenge, or just wanting to fight the final boss (whichever rocks your boat).

Version 1.1 Recommended - Yes
