Suddenly, a wild naked babe appeared! Ready to get those childhood memories of playing the classic Pokémon games (on your Gameboy) ruined by mixing in some good old fashioned hentai content, plenty of nudes, and a kinky storyline? That's where these fan-made ROM hacks come into play.

ROM hacks are similar to mods for PC games. In other words – these ROM hacks are modifications to the source code of the original Gameboy (Advance) Pokémon games, and in today's case, will drastically change the entire game. For the better, that is!

One warning though - some things just can't been unseen! Time to say goodbye to your childhood!

NSFW Adult Pokémon ROM Hacks - Gotta play 'em all

You're about to witness the Pokémon universe and all the characters you're already familiar with but in a way, you've never seen them before... that includes stripped naked, tied up and ball-gagged!

Oh well, I guess this is the reason why Nintendo doesn't like it when fans start "messing" around with their family-friendly entertainment systems by creating their own unauthorized smut.

Got tired by trying to catch and level-up Pokémon? More in the mood to start catching horny girls to keep as sex slaves instead? What about abusing your Pokémon's psychic abilities for mind-control in order to get yourself laid? That's just a few of the many kinky changes made to the original games.

Without further ado, here are the 7 best Hentai Pokémon ROMs, you'll simply have to play and experience yourself! The ROM hacks on this list are fully loaded with hentai, nude content, sex scenes, and are being presented on your screen in 16-bit pixel-art, just like in the "good old days".

Pokémon Psychic Adventures (GBA)

Enter Pokémon Psychic Adventures, a NSFW ROM hack by EviLGRiN, based on the Gameboy Advance game – Pokémon Fire Red.

The player's journey starts in the Kanto region. Once you've picked one out of three starter Pokémon, the player gets prompted with the question whether he wants to make a move on his female rival (called Blue) by giving her a kiss. Well, why not, right?

Sadly though, a tiny little kiss is all you're going to get... for now.

But fear not! Maybe, just maybe, if you train your psychic Pokémon-type well enough, you might end up levering their "special mind-controlling abilities" for your own dirty little perverted desires. Think of all the naughty possibilities this might bring!

Pokémon Psychic Adventures explores the concept of mind-control in a sexual way. For example, once you've captured a starter Pokémon such as Drowzee, and leveled him up until Drowzee has reached level 15 (at minimum), the player finally gets to use - or should we say abuse - Drowzee's hypnosis attack move to put female characters into a deep trance (deep sleep), followed by the option to "touch her boobs".

Rubbing their boobies is just one of the many possibilities this ROM hack offers. Try to train your Drowzee to level 20 and you will be able to put her to sleep and control her mind into stripping bare naked.

And well, the further you progress in the game (and the more you level-up your Pokémon), the dirtier things are about to get. From fingering to facials, and really no hole is safe because these female NPC's are even taking it up their butt. Reach level 60 and anal sex will become an available option to choose from.

So, you think you've got the "balls" to start playing Pokémon Psychic Adventures? If you're down for some mind-control fun, go play Pokémon Psychic Adventures!

Pokémon Ecchi (PC & Android)

Pokémon Ecchi aka Pokémon Ecchi Version, was developed by Hinorashi and got released in 2019. Even though this one technically isn't an official ROM Hack, we simply do had to put it on this list, because it's just that well made and fun to play.

This one right here is a (fan-made) remake that looks, feels and plays exactly like the original game series by Nintendo, but yet, was still build from scratch (instead of made through hacking the original Gameboy soure code).

Does that make any difference in terms of gameplay? Not one bit! And boy, with a game title like that, it sure doesn't disappoint... In fact, it's about to get real spicy, really quick!

It's also one of the most impressive adult Pokémon clones ever made, not just for remaking the entire original game engine, and also not just in terms of the storyline, but what makes Pokémon Ecchi truly impressive, is the fact it adds a ton of new gameplay elements, which of course, includes a whole lotta "fucking and sucking".

For starters, Pokémon Ecchi takes place in Midara Region, a fictional region in the north of Sinnoh region, and let's just say – the laws and rules of that region differ quite a bit, especially in terms of sexual acts. But that's good news for the fans of hentai action, because this Pokémon ROM hack features a ton of spicy pixel-art content, including fully animated sex scenes and contains plenty of well drawings.

By the way, Pokémon Ecchi doesn't discriminate when it comes down to steamy sex - if that cute little Oddish wants to bang a blonde girl, Oddish gets to bang a blonde girl. But there's also girl on girl action, girls giving head or getting fucked doggystyle etc. Basically, it's one happy orgy at Midara Region.

Pokémon Ecchi delivers a completely new experience, and isn't just one of those game mods which only changes a few sprites or graphics. For starters, even the gameplay offers a lot of new features. One example would be – the player has the ability to put on new clothes or take them off entirely. Yes, you can explore the Midara Region while being completely stripped bare naked.

The dialogues and other events even change, based upon the player's decision to walk around the area clothed or nude. How awesome is that? The chances of getting "attacked" will also drastically increase when you're exploring the world map in your Eve-costume.

Another added feature to the gameplay is the "arousement-meter", which shows how turned on these characters are when you are "making love" with them.

In this erotic version of Pokémon you'll stumble upon many sexual encounters (from blowjobs, handjobs, grabbing boobies to strap-on dildos and other sex toys). There's also many puzzles to solve, gym leaders to defeat and like in any other classic Pokémon videogame title - items and badges to collect.

Want to get your hands on an item such as "the lucky egg", well, be ready to get down on your knees... That's Pokémon Ecchi in a nutshell for ya. And I tell you, it might all sound quite silly, it sure is damn fun to play and just as addictive as the original Pokémon games on the Gameboy.

Pokémon Girls Hunter (GBA)

In Pokémon Girls Hunter the player gets introduced to Puela region, an Island with a predominantly female population, not necessary by nature, rather by design, at the hands of "The Goddess". So far, so good... Until Team Rockets arrives.

Right at the beginning of the game, we get to see the return of the evil Team Rocket. This time around, they introduce the player to their own modified Pokéballs prototype, which they call "Human Balls". And as you might have guessed already, these special "balls", have the ability to catch and capture human females, which they plan on using as sex slaves.

The player takes on the role of the protagonist Seda, which is send (by her female police-offer friend Cassie) on a quest to try and to get hold of all the "Human Balls", not to let all the captives free, but more in order to use them for their own naughty, personal wishes.

But, if you lose the first battle, right at the very start of the game, you'll instantly become a sex slave yourself. Does that mean "Game Over" for the player? Nah, it just means the protagonist gets to walk around with a ball-gag in her mouth and is being ripped out of her clothes. That doesn't sound like the end of the world, right?

Basically, in Pokémon Girls Hunter (made by fz15), you'll get to grow your own harem of nude girls (or more like sex slaves), instead of trying to catch all Pokémon.

This Pokémon Girls Hunter ROM hack adds a ton of new features to the original (GBA) game Pokémon FireRed, and treats the player to a totally new and unique Pokémon game and storyline. A much kinkier one. You won't be able to notice you are in fact playing a modified version of the original FireRed GBA game, as it feels like an entire new RPG adventure game (with the quality of the original Nintendo franchise).

Once you start playing, get ready to explore area's such as Doll Island or meet characters such as "The Doll Master" or "Horny Devils", and yes, of course, also be prepared for a whole lot of hentai action popping up on your screen while playing this NSFW Rom hack!

Think you've got the skills to grow your lesbian harem? Gotta catch 'em all, right? I'd say - go for it.

Pokémon Girls Hunter 2 (GBA)

Every good Pokémon Hentai game needs a sequel, right? Fz15, the author of the original ROM Hack was probably thinking the exact same thing. And thus, the sequel called Pokémon Girls Hunter 2, once again, is based on the GBA game Pokémon FireRed and finally got released back in 2020.

The best news of it all – it sure lives up to its hype.

The game takes place after the events of its predecessor. Thanks to Seda, the heroine of the first title in the series, has managed to bring back peace to Puela Region by defeating Team Rocket.

This time around, those "Human Balls" with the ability to catch female humans in order to turn them into sex slaves, are suddenly popping up all over again, this time at the Tiara Region.

It's up to Ankell - a returning character from the first Girls Hunter game - to save day. And by saving the day, I mean – catch as many girls as possible and eventually, save the day once again.

With over 50 different kinds of catchable girls, and 10 Pokémonrph girls, you'll be having "your hands full" for the next couple of days while trying to play though this entire Pokémon hentai ROM hack.

Which won't be an easy task, by the way. This neat ROM hack can get quite challenging, and will likely keep you occupied for many hours while you're trying to find all the hidden items which are are needed or to figure out on how to solve all the in-game puzzles.

Pokémon Cock Version (GB & GBC)

Pokémon Cock version is a ROM hack of the classic Gameboy game – Pokémon Red. However, the original story has changed quite a bit in comparison to the "Cock version", to say the least.

Just like in Pokémon Red (and Blue or Yellow, for that matter), the game starts in the main protagonist's bedroom. After waking up and moving downstairs, you'll get to talk to your Mom, who will tell you to go visit Professor Oak. Well, at least, that's what Mom says in the original game.

In this Cock version however, your Mom will tell you, and I quote – "Go visit that old ass man before he fucks her in your bedroom". Yup, turns out that old dirty bastard has been shagging your Mom all that time after all... Boy, that escalated quickly.

When you proceed to Oak's place, he will tell you he's an old man that it simply looking for some entertainment, either you or your rival have the chance te become champion. There's a big catch though, you'd better win the Pokémon League at the end of the game, because, and I quote the legendary Professor Oak once more – "The loser will be raped".

Now that is some next level "entertainment", if you'd ask me.

When the player embarks on his journey, he gets to pick one out of following three starter Pokémon – Lickitung, "the pussy eater", Mr Mime (we can't quote this, for real), and Mew, "the TM Whore".

Also, when you talk to random NPC's at the start of the game, they will warn the player to be aware of the "boner ghosts", which will try to rape you. You can't make that stuff up. I think you'll get the overall "bad taste humour" this rom hack is all about by now. It just tries to be as gross and vulgar as possible.

Is it any good? No! It's really bad.

Then why did Pokémon Cock Version made this list, you'd ask? Well, it's so bad, it's good! But I fully understand that fart, piss and poop, as well as highly offensive jokes, aren't exactly everyone's cup of tea.

Easily offended? Do yourself a favor and skip the Cock Version of Pokémon. It's far worse than you are probably imagining right now. ;)

Pokémon Girls Hunter Halloween (GBA)

Good news for the fans of the series, because Fz15 decided to go end his saga of sex slaves with a trilogy!

That being said, this third entry called Pokémon Girls Hunter Halloween, is quite a bit shorter ROM hack in comparison to its two prequels, but that sure shouldn't spoil the fun as it still offers many hours of gameplay in order to play through the entire game.

The game takes place on Holiday Islands and introduces a new heroine – Horie, a girl who managed to escape and distance herself from the Slutian family.

The game tells the story of an Island filled with ghosts, a haunted house (plagued by two murderers), evil wizards, killer birds and all sorts of other creepy crawlers which you would expect to appear in a Halloween-themed game. Oh, and of course, once again, there's a lot of sex toys, milk draining, boob touching, pussy licking, fingering and penetration involved.

Basically, you can expect usual stuff which the Girls Hunter series is known for, but of course, since it's a Halloween title, there's plenty of horror elements to unravel as well.

Even more hours of gameplay to enjoy for the fans of this fan-made series thanks to the release of this final entry, which serves as a perfect way to end this ball-gagged Pokémon game trilogy for once and for all.

Pokémon Pigment Ruby (GBA)

Pokémon Pigment Ruby is an adult ROM hack of the Nintendo Gameboy Advance game – Pokémon Ruby, but with quite a lot more boobies popping up on your screen. The ROM hack was made by the author known on the internet as Daisy (aka Daisy Problems), and was first released back in 2015.

This perverted ROM hack follows the story of Kris and May.

Almost all the original trainers, both female and male, as well as the Gym leaders have been replaced by topless girls, from cheerleaders to a pirate chick. Besides adding a few new and more Gym leaders, this ROM hack, for the most part, only offers a limited amount of changes in comparison to the original GBA game.

Pigment Ruby might not be the most unique or most impressive ROM hack on this list, that being said, it's still entertaining and a perfect match to those that aren't looking for an entire new game experience or too many large changes, but rather prefer to recapture that magic of the original Pokémon classics, but with a lot more spicy ingredients being sparkled on top.

Current development can be followed on their official blogspot page, however, it hasn't been updated in quite some time.

Is it legal to download ROM hacks?

While it isn't illegal to modify a game (create mods or ROM hacks) or have an extra digital copy of a game on your device, as long as you own the original product itself. Meaning, it would only be legal to play ROM hacks, if you purchase or already own the original Gameboy cartridge.

This is also the reason why this article doesn't contain links to all the downloads. That being said - if you do happen to own the original games, you are free to search the internet for the download links (it's not hard to find).

How to play these GBA Roms On Android Devices?

In order to play these fan-made ROMs, you'll need to use an emulator to boot them up. An emulator is a (free) piece of software, which you can install on your PC or Android, tablet or smartphone.

For Android users, we recommend the Pizza Boy GBA app, simply because it plays Gameboy Color and Gameboy Advance games in 60 frames per second, completely free of annoying advertisements, and best of it all - the emulator app is entirely free.

How to play these GBA Roms On Your PC?

Looking for a way to play Gameboy, Gameboy Color or Gameboy Advance games or ROM hacks on your PC? We've got you covered too!

Personally, I have been using the Visualboy Advance emulator software for many years now and love it. It's lightweight, fast, easy to use and because it simply always does the trick without any hassle!

To boot up a game (ROM file), all you have to do is launch the Visualboy Advance app on your Windows PC (or Mac & Linux), click on Load ROM (in the top menu bar) and select the ROM file you want play.

That's it, you're ready to embark on a new and racy journey! Time to get your "balls" out... Pokéballs, that is!
