In 1987, Nekketsu Kouha Kunio-kun was the first video game that Technos Japan ported to a home console. The system they ported the game to, the Famicom, could display no more than three enemy characters at one time. However, in converting it for play on the Famicom, they compensated for the technical limitations of the hardware by expanding the play experience, spreading the first three stages over several scenes, and making the quest to reach the final boss a veritable maze of rooms to explore. In 1988, Taito took Nekketsu Kouha Kunio-kun for the Famicom, and gave it the same cosmetic alteration in to Renegade for the NES as they had done for the arcade version. Much later, in 1993, Natsume converted the game for play on the Sega Master System late in the console's lifetime, published by Sega in Europe. As a result, it is a little known conversion of the game. It is heavily based upon, but not entirely identical to, the Famicom/NES version of the game, featuring different graphics and making use of the SMS's enhanced pallet. As such, much of the descriptions of the NES version are applicable to the SMS version as well.
It is important to note that during every scene change, you will automatically regain all of your lost health, and the 2 minute timer will reset.

Stage 1
The first stage still takes place on a subway platform (or a train platform in the Famicom version), but now it takes place over three scenes. The boss no longer waits for you on the platform that you start on. Instead, he is a stop away, and you'll need to ride the train, and defend yourself along the way, to reach him.
- A: You start out on a platform that is fairly identical to the arcade version. As such, there is a drop on the right side of the platform which you can use to your advantage to immediately knock or throw enemies over the side. It can also contribute to your own death if you're not careful. You must defeat eight enemies before the doors on the train will open up. At any given moment, you will be fighting against two brawlers, and one stick wielder.
- B: Once inside the train, the fight will immediately continue. The train has no special features, so you must completely defeat each enemy. The same make up of fighters will approach you until you have defeated six of them. Then the train will come to a stop and the doors on the back side will open.
- C: You will face off with the boss on the smaller platform. Do not attempt to throw or knock the boss off the edge of the platform, you simply will not be able to do it until the boss is much weaker. Attempting to do so could backfire on you, and cause you to fall down instead. Likewise, you will not be able to sit on the boss and pummel him unless he is down to only one bar of health. Rely on jump kicks and dashing punches until he is defeated.

Stage 2
The second stage takes place on the biker's pier, just like in the arcade. However, the order of events has been altered, and you must fight the gang on foot before you face any of the motorcycle riders. After you knock off the last rider, you will have an opportunity to grab his bike and go on a freeway ride to the boss. But don't expect to get there without a fight.
- A: As mentioned above, you will have to fight the gang members on foot first before dealing with any motorcycle riders. Use the left side of pier the same way you used the right side of the platform to make quick work of the gang members, but use caution.
- B: After taking out a number of gang members, the gang resorts to trying to mow you down with their bikes. Unlike the arcade version, you only ever have to deal with one at a time, making the ordeal substantially easier. In addition to that, jump kicks are far more reliable than they are in the arcade, although you must still time them carefully in order to succeed.
- C: After knocking out the last rider, you grab his bike and start riding down a highway to reach the boss. Along the way, several bikers will appear and try to kick you while you're riding. In addition to running out of energy, you must also beware of falling off the bottom side of the road. Press
to kick your opponent. You will automatically kick on the appropriate side of the bike. It is much easier to kick and defeat your opponents if you are moving left or right as you do so. Holding still will make it harder and expose you to more injury. You may encounter an "S" icon along the way. If you collect it, you will be able to ram into enemy bikes and knock them out by pressing 
. - D: After the long bike ride, you will finally make it to the parking lot where the boss of the stage is waiting to fight you. This fight will not be substantially different from the previous boss fight, only you do not have to worry about falling off a ledge. Jump kicks and dashing punches are the key to victory.

Stage 3
The third stage is an interesting stage in these home conversions. It offers a branching path, but stage can be completed and passed if you take either path. The only question you need to ask yourself is if you would prefer to face a second angry mob of women, or one very large and very angry stage boss.
- A: Just as in the arcade, the third stage takes place in a seedy alleyway outside a bar and night club, occupied by an all female gang. With no edge to rely upon, you'll have to defeat these women the normal way in order to advance further into the stage. When the last female gang member is defeated, you'll have two entrances to choose from. The door that opens up leads to part B, while the stairs to the right lead to part C.
- B: Inside the bar, you'll find even more disgruntled women. And they won't take kindly to you crashing their hang out. The screen will not scroll, so you're limited to the space available in the bar. Still, no more than three women will ever confront you at one time, so space should not be much of an issue. If you knock out all of the women in this bar, you will advance to the next stage without confronting the boss.
- C: If you choose to take the stairs, you will only have to face off with one woman. But this is no ordinary woman. She is gigantic and can take a lot of punishment. Most of your traditional boss fighting methods will not work as effectively against her. The safest way to fight her is to run a good distance away from her, and let her chase after you. Stop and turn around, And jump kick her in the jaw when she's close enough. It takes three consecutive jump kicks to make her fall down. Then you can repeat the strategy from the opposite side of the room. If she gets close to you, she will pick you up, pummel you, and throw you, so don't get too close. Dashing punches will also work, but only if she is not in the middle of attacking you already; she will usually knock you down if she is.
