Today, we bring you a prototype of Bugs Bunny Rabbit Rampage for the SNES with unknown differences compared to the final version. Thank you to PrimalConcreteSledge for dumping this and sending it to us for release!

Hey folks! We have an anonymous release today of a very early Punch-Out prototype! There's a lot to see in it (but not hear); check out the @gamehistoryorg.bsky.social video here! www.youtube.com/watch?v=3T5A...

We've released a v3.1 update to our 3DS EmuNAND kit to address some technical issues. If you've had technical issues when using the kit, please try running this new update.

Proto Challenge presents... A lot of Nintendo 3DS system software prototypes + a very early prototype of Kid Icarus Uprising! This release has been a long time coming, and we're happy to finally have it all working on retail hardware for anyone to try. 🧵

The stream is starting soon. 👀

Friendly reminder: this is about 12 hours away. 👀

In partnership with @protochallenge.bsky.social, I'm happy to showcase some new 3DS system software prototypes in a livestream on April 4th, 11:45 AM Eastern / 8:45 AM Pacific. Joining as co-commentator will be @jamesmoney.bsky.social! Hope to see you there! youtube.com/live/MDdX0b-...

Thanks for 100 followers! We'll have an exciting announcement coming tomorrow. 😱

You may recall we announced that a live stream showcasing new prototypes would be happening sometime in March. We've delayed this stream to April 4th at 3:15 PM UTC. More details will be announced in the coming days.

This is a prototype of the unreleased Game Boy Color version of 40 Winks! This build has 6 playable levels and 2 playable characters (Ruff and Tumble). It seems to have been from very far along in the game's development. archive.org/details/40-w...

Today, we bring you a prototype of Mario's Picross for the Game Boy! Dated January 23rd, 1995, this build comes a few months before release and contains different puzzles, a different Super Game Boy title screen, and other graphical differences. archive.org/details/mari...

Today marks 15 years since the 3DS released. To celebrate, we'd like to announce that in March, we'll host Proto Direct: a live stream showcasing newly found game prototypes for 3DS and other systems too! We'll announce an exact date/time at a later date. Follow us here to get notified of updates!
