New SNES Game: Yo-Yo Shuriken [Cartridge+ROM]

Recommended Posts

After a long and hard work both on the software and hardware front, I'm happy to announce you the release of my first SNES game: Yo-Yo Shuriken.


Defend the dojo!

Use your secret ninja weapon, the mighty "Yo-Yo Shuriken" to defeat the robot hordes and their deadly bosses.
Master the technique of throwing the shuriken to attack enemies from the front and then recalling it to hit them from behind! Focus your energy into the Yo-Yo Shuriken to deliver a powerful charged attack that can cut through several enemies at once!

  • 7 levels of intense action!
  • Solo and 2-player co-op modes!


The game is now available on cartridge with a beautiful cardboard box and a manual from Catskull Games:


!Black Friday Sale!
All the games from Catskull Games, including Yo-Yo Shuriken but also my previous Game Boy games (Sheep It Up! and DMG Deals Damage) are 10% off until December 2nd, 2019!
At checkout, enter the promo code BF2019 to get the discount!

The cartridge is made from newly built elements (PCB, shells, etc.) all designed and hand assembled in the US by Catskull himself. The cartridge is region-free. It has been tested and working on NTSC SNES, PAL SNES, JP SFC, and Analogue Super Nt. The box and manuals are also printed and hand assembled in the US, using materials that make them as close as possible to the original SNES releases from the 90's!

Also, you can also buy only the ROM of the game if you prefer to play it on emulator:

Whether you play it on real hardware or on emulator, I really hope you'll enjoy this game!

My copy came in today, it’s fun and harder than it looks! In addition to need to hit Y again to make the shuriken come back to you, if any enemies get in the way of its return, the shuriken stops there and you have to hit it again to make it come back. I really like that touch because it makes me really strategize where to move as I throw it. Great job!

Hi everyone! Like many other devs, in order to bring everyone a few  minutes of escapism during these hard times, I'm making my Super Nintendo game "Yo-Yo Shuriken" free for this weekend!

You can get the game here during this weekend:


I wish you all courage and hope you'll enjoy it.

For those of you who are interested in "how to make a SNES game", I've just published a long article about making my SNES game Yo-Yo Shuriken.

It starts with the various steps I went through to design and program the game. Then, it details how we manufactured new cartridges (with box and manual) for a console whose commercial support ceased more than 20 years ago! (spoiler: all cartridges and boxes and hand-assembled for each order!)

You can read the article here:

I hope you'll enjoy it!
