Hi! It's cool to see players getting creative :)! Out of curiosity, what emulator do you use that allow you to set custom icons for each game?

And as requested, here is the Game Gear front cover

And here is the Master System one:

I hope it fit your needs, and feel free to ask me if you need anything else!

I hope you'll enjoy the games :)

Thanks, I hope you'll enjoy the game! 

Regarding the cover image, does the front of the box below would fit your need?

If not, I can try to make another one. What resolution do you need for the cover image?

Thanks, I'm glad you enjoyed it!

Thanks a lot for your support! I hope you'll enjoy the game :)

Hi! Thanks for your interest, I love the GG and the SMS, and it's great to see that more and more homebrew games are created for them (especially thanks to the annual SMS Power! dev competition).

To answer your question:
- The Game Gear and Game Boy versions are identical gameplay wise (same controls, difficulty, and levels). Only the graphics and sound are different (the original version being the Game Gear one, and the Game Boy a faithful port of it).

- The Master System has three main differences compared to the Game Gear version :
1) This version doesn't feature an "auto-fire" option (holding down button enabling automatic repeated fire). Each time you press the button, a short is fired and that's all. The auto-fire feature was added the Game Gear version (and so the GB one too) thanks to player feedback after the SMS release, as this one was the first to be published.

2) The levels designs are often different,  to use the extra screen space provided by the Master System (256x192 screen area, compared to 160x144 on Game Gear and Game Boy).

3) The gameplay of the Game Gear version was "tweaked" to reduce the difficulty, as playing on a smaller screen area naturally makes the game harder. So the player moves slightly faster in the Game Gear version, and it also has a smaller hitbox.

Besides these differences, they play the same, and sound identical (Game Gear and Master System use the same audio hardware).

If you try several versions of the game, please let me know the one that you prefer :)!

Thanks! :)

Well, maybe someday :)!

I do plan to port it to other machines, although I'd like to target lesser know machines with this game. But the NES is also on the map, as it's a very fun machine to develop for (I have another NES project in the work, that will hopefully be completed by the end of 2026).

Merci, j'espère que le jeu te plaira ! La version Game Gear est la version "originale", celle qui a été developpé en premier, même si elle n'est finalement sortie qu'après la version Master System. Du coup elle a bénéficiée de petits ajustement du gameplay (le tir continu en laissant le bouton appuyé notamment), qu'on retrouve aussi dans la version Game Boy.

Bon jeu !

Hi! Yes, this is an actual Atari 2600 game. You can use the files here to play on a real console if you have a way to put it on a Atari cartridge. For that you can use a Flashcart, like for example an Harmony cart or a Unocart / Pluscart device who can load games from SD cards and run it on an actual 2600 or 7800 console.

Avec plaisir, merci pour les encouragements!

La version Game Boy / Game Boy Color / Super Game Boy devrait sortir en premier, normalement d'ici la fin du mois, avec je l'espère une édition physique. Pour la version Mega Duck, elle est prête à 95% (car la console est en fait un clone quelque peu modifié de la Game Boy), donc elle la suivra peu de temps après :).

Amusez-vous bien avec la version SMS aussi !

And thanks to you for all your hard work on making such a gorgeous physical Game Gear release! :)

Heya! Your message motivated me to do it, so I'm happy to announce that the ROM for Dangerous Demolition for Game Gear and Master system are now available here:
https://drludos.itch.io/dangerous-demolition

I'm also working on other versions of this game, that should be released in about a month: Game Boy / Color and Mega Duck / Cougar Boy. They'll be released on the same page when available.

Thanks again for your interested in my games, and I hope you'll enjoy Dangerous Demolition!

Thanks for the kind words, I'm glad you enjoyed the game! :)

The USB-A plug variant would be incredible, maybe for a PC with an USB hub. We could even make it harder by connecting several hubs to have for example 12 USB-A ports! :)

Thanks for the kind words, I'm glad you liked it! :)

And believe it or not, yes, we could indeed image making a version when we had to plug a pad accessory like a Memory Pal, a Transfer Pak or a Rumble Pak. Indeed, the N64 can detect any kind of accessory connected to its ports with great accuracy :).

Hi! Thanks a lot for your interest in Dangerous Demolition. I'm still working on the digital release of the GG and SMS versions, they should be available by the end of this month (February).

I'll post another reply to this comment to let you know when they are available if that is ok for you! 

Thanks! :)

Hi, thanks a lot for the video! It's a great pleasure for me to see players enjoying the game, thanks for making and sharing the video :)

Here are some answers / comments to questions asked during your video:

- During the "Arcade" and "Contest mode, your score increases and you must make the best score. Each treasure earn you a defined amount of points: 3 points for a coin, 4 points for a diamond, 5 points for a ruby. And hitting and killing skulls earns you even more points (10 for a regular skull, 35 for a boss).

- In the "Levels" mode, you must collect a defined number of treasures / kill a fixed amount of enemies to clear the level. So in this mode the score decreases each time you "earn points". When you reach zero you clear the level, like you did in the video.

- The levels all looks the same (there is a single "brown" area), but each level has a different layout (type and place of treasures and enemies). Each level is hand-tailored to offer a slightly more difficult challenge each time you progress in the game.

- You should definitively try the level 4, you're in for a "big" surprise that you haven't discovered yet in the video.

- The "digging power" of the minigun does not vary over time, you have the same power whether you are playing level 1 or level 16 - only the challenge you face becomes harder :).

- The "TV" setting in the main menu allows you to configure your TV type when playing on real hardware to have the game look right on every machine region. When played on a PAL console (so Europe and Australia) the game will look strange on startup, as it'll be configured as a NTSC game. But selecting the "TV: PAL" setting will make the game look as good on PAL machines as on NTSC consoles. The Stella emulator that you use runs in NTSC mode by default. And the SECAM TV type will display colors when played on an actual SECAM version of the 2600 (exclusive to France, can display only 8 colors instead of the 100+ colors of NTSC and PAL versions). But the "SECAM" setting doubles as a "Black & White" mode when played on a NTSC or PAL machine.

- There are a lot of other Atari 2600 homebrew for you to try if you like the console, the scene is very active since a very long time. The best place to find them are the AtariAge forums. For example, James from the ZeroPageHomebrew Twitch show is keeping track of all homebrew released each year, for all Atari consoles. Here is the Atari 2600 list of homebrew released in 2025: https://forums.atariage.com/topic/378304-atari-2600-homebrew-games-releasedcompl...

- And as requested, here is the front cover art, drawn by the wonderful William Thorup (commissioned by AtariAge, who published the physical release). It's not the final-final version (it lacks the copyright info in the bottom right) but the image is the final one :).

Heya! Thanks for your video, it's always a pleasure for me to see players enjoying the games I make :). Congrats on going over 1 minute, as the game is challenging :).

This game was made in 48h during a Game Jam, so that's why it's a bit "rough" around the edges. I latter refined this same idea to make a more polished SNES game titled "The Last Super", that you can play here:
https://drludos.itch.io/the-last-super

And to answer your question in the video, yes, "Yo-Yo Shuriken" is an actual SNES homebrew I created back in 2019. It was released in physical edition (cartridge, box & manual). You can play this one here:
https://drludos.itch.io/yo-yo-shuriken

Enjoy!

Thanks, I'm glad you liked it! I watched your stream with all the DOSember Jam games, and you can use left and right mouse buttons to rotate the balls, that will make going farther much more easier :). Sorry that the in-game instructions weren't clear enough (i should display them on each game over screen maybe).

Thanks for running such a cool MS-DOS jam! :)

Thanks, I'm glad you enjoyed it!

Hi! Yes, the game cart does work on a 7800+. I've tested it on a never updated 7800+, so on still on firmware 2.0 (so like any 7800+ coming straight of a brand new box).

Hi,

Same problem here as everyone: newly uploaded GIF are not animating. It seems that the image server is simply keeping the first frame and "discarding" all the other remaining frames when we upload it.

Here for example, this GIF of my latest game weight about 328kb. After uploading, it's now a 8kb GIF image with a single frame. So the issue seems  related to how the GIF are processed when uploaded to itch.io.

Thanks for your hard work, I hope you'll be able to fix this, as is this very annoying to not be able to show players how the game "moves" in the description post.

Merci, content que mes jeux vous plaisent ! :)

Pour la Supervision, j'aimerai effectivement m'y attaquer un jour, car je trouve la console intéressante, c'est comme une "Game Boy" d'une réalité alternative :). La console possède un framebuffer, donc elle peut afficher des dessins "au pixel près" contrairement à ses concurrentes basées sur des tiles et sprites. C'était un choix original pour l'époque.

Il y a déjà eu un homebrew Supervision très sympa il y a quelques années, Assembloids: https://www.polyplay.xyz/Assembloids-Standard-Edition-Supervision

Pour la Gamate ce serait intéressant aussi, mais pour l'instant je ne possède pas la console, donc je ne le connait pas encore vraiment.

Merci pour vos encouragements, c'est très motivant !

Thanks :)!

Woaw, this is gorgeous, congratulations! :)

Thanks a lot for drawing such a cool "fan-art", I love it! :)

I'm happy to accept your offer to email me the files:

Thanks, I'm glad you liked it! :)

Thanks a lot for your comment, I'm glad you enjoyed it!

Hi! 

If you have a SD2SNES or a FXPakPro you can play the game on real hardware without a SGB, as this flashcart can fully emulate a SGB1 or 2.

There are also a few emulator able to run this game (Higan, Ares, BSNES and Mesen 2.0, including their RetroArch cores)

This is great idea!

Thanks a lot for giving exposure to our game and encourage players to try them!

Hi! 

Don't be worried, your FXPakPro is working great: the "SNES Sprites" feature of the SGB does flicker, whether you play it on real hardware or emulator.  I designed the game with a plain white background to try to mitigate this issue, but the SNES sprites will still appears translucent / ghostly due to the constant flickering.

I'm sorry if the game page description wasn't clear on this topic, but this feature is flawed due to the flickering, and that's likely why Nintendo disabled it. The "fix" performed by this game is to be able to enable this feature back (it's normally locked away), but I don't think anything can be done to prevent the flickering.

I tested my SD2SNES (previous name of FXPakPro) and it does emulate the SGB1 and SGB2 perfectly to my eyes: I didn't notice any difference running my through an actual SGB / SGB 2 and the FXPakPro while testing my game.

Yes, this is incredible, it's great to see so many new SNES game! Congrats to everyone, and thanks a lot to the Jam organizers for running it! :)

Hi Svambo,

Thanks a lot for accepting to let the game be present on the Jam due to its "uniqueness" despite failing to meet the technical requirement for the multicart.

There is a lot of great entries this year, it great to see that the Jam manages to motivate people to create new SNES games :)!

Hi! You have a good idea, but it's actually a bit more complicated than that. The VRAM upload in the sprites area is permanently disabled in the SGB BIOS, like the "SNES Sprites control" function. According to the SGB documentation, you can set a flag for the VRAM upload to send data to the sprites area, but in reality, the code of this function in the SGB BIOS disregard this flag and always send data to the "background area".

It may be possible to patch the SGB Bios to restore the VRAM sprites upload, or to try to manually send graphics data a few bytes at the time using the general "SEND DATA to SNES RAM" function. Thanks to Nenson Dubois research, this function is used in my game to patch the SGB Bios to enable the "SNES Sprites" function, so there is still hope that it may also be possible to restore the sprites VRAM upload too.

But regarding the sprites flickering, I fear that this issue will never be solved, as I think that's what led Nintendo to disable the "SNES sprites" function in the first place. As the SGB Bios read the Sprites OAM data from the content of the GB Screen sent by the SGB (so from a portion of SNES VRAM actually), I don't think the SNES will have the time to do everything and maintain a 60 fps update.

Hi, thanks for the heads up! I personally used higan during this project (as it's almost 100% accurate and the one I'm used to), but I guess I should try to include Mesen 2.0 too, sounds neat that they support so much systems!

Hi, thanks for your feedback. I too enjoy trying to push our beloved retro consoles whenever possible :)!

Hi, I'm glad you like it!

Regarding the technical constraints, sadly yes, as the game requires a Super Game Boy to work (or a SD2SNES / FXPakPro emulating the device), it won't be able to be featured in the cartridge compilation. The game is only 32kb in size, but it needs the extra hardware contained in the SGB to work (basically, a stripped down GB motherboard).

I'm sorry for not being able to 100% adhere to the technical constraints with this project. But I found very interesting and unique to be able able to control SNES sprites and BG color palettes from a GB program, unlocking a "hidden feature" of the SGB device in the process.

I'm obviously opting out of any prize or rank in fairness for the other participants. But I hope that the game can still be played and reviewed by the Jam jury, as I'm always interested in feedback, and I'm happy to spread the word about the "unused power" of the Super Game Boy :).

Thanks a lot for your comment, I'm glad you enjoyed it! :)

Hi everyone!  

I've just submitted my game, titled "DMG vs. Super Game Boy".

My entry is a bit "special", as it was created for the Super Game Boy device. But this is not a regular Game Boy game: it relies on a "hidden" feature of the device to control and display actual SNES sprites in addition to everything rendered in the GB screen area.

It also also uses other SGB features to colorize the screen and play sounds using the SNES sound chip.

You'll need a SNES + a SGB1 or 2 or a SD2SNES / FX Pak Pro to play this game, or you can use a SNES emulator with full SGB emulation like Higan, Ares, BSNES or Mesen S. 

I hope you'll enjoy it, even if it's not a "standard" SNES game :)!

Thanks for the suggestion, this is indeed a very nice publisher.
My publisher Yastuna used their PCB for the release of Sheep It Up! and DMG Deals Damage :)

Thanks again for your interest, I'll keep you updated on this topic!

Hi! Yes sadly my publisher Yastuna Games has closed shop at the end of 2024. They still had a few copies of my GB games Sheep It Up! and DMG Deals Damage in stock. So I'm hoping that another publisher will be interested in picking up the remaining stock and sell it. But my 3rd GB game, GB Corp, was sold out.

I don't have an idea when (and if) this will happen, but I'll post a message again here if this game become available for sale again.

Thanks again a lot for your interest in my games :)
