Last year, LNRC partially preserved CROWS x WORST, a beat-'em-up keitai game based on the eponymous manga series. Today, @yuvi.app created a server, which made it playable for the first time! The game heavily relied on server data, so our copy is a small portion of the full game.

What a blast of a game to Reverse Engineer, I gave up many times to come back and finally get it working.
Gundam VS Fighting Spirits Plus, which was preserved last year, is finally playable thanks to @yuvi.app! The game needed a server to function properly. This may be the best keitai fighting game we've preserved so far. It runs incredibly smoothly for a keitai game.

Are you at MAGFest? Want to try some preserved keitai games? You're in luck! Come to the Museum/LAN Room and look for @unabandonware.bsky.social's table with 20+ Japanese feature phones! Unabandonware is one of the foremost keitai game preservationists, and she'd love to tell you all about them!

I also need to highlight someone else’s contribution to the Magfest museum this year: a slew of Japanese keitai with games on them! These were staples of Japanese gaming pre-smartphone, and it’s rad to see them presented here on their original hardware.

Thanks to an individual who helped implement the MLD format to a near-perfect replica. We have one of the best Keitai music players to exist now. This will be coming out sometime in the future, but I wanted to give everyone a sneak peek!

Keitai World Launcher now includes the Free-J2MEPlus emulator, which supports EZplus Java games! You can play preserved EZweb games like #Tetris Outdoor, which features Linda from Stretch Panic... an unexpected crossover! KWL will have more EZweb game integrations in the future.

After some SD card bruteforcing, the downloaded i-mode trial of Professor Layton and the Curious Village was preserved by @unabandonware.bsky.social and @yuvi.app ! Unlike the preloaded i-mode trial, this contains all of chapter 1 and is closer to the original DS game (voice acting, cutscenes).

Dozens of i-mode games with Mobage and GREE server functionality have been revived, thanks to @yuvi.app! Many are score attack variants of games like Galaga and Taiko no Tatsujin. In the near future, Mobage/GREE leaderboards will be viewable on the Keitai Archive website.

Please go support and congratulate @hilltopworks.bsky.social and @cargodin.bsky.social They are close friends of mine, and they just released their first-ever official translation work! It would mean a lot to me to see them succeed for the amazing effort they put into this!
Milano's Odd Job Collection, our revival of a gorgeous pixel art PS1 game from 1999, is now out on all platforms!

Happy to have helped preserve this unreleased PS2 game, “Rubu Tribe”.
This game is certainly interesting, and I could have seen it doing well if it had been released back in the day.
This contains multiple compiled levels and some test levels as well.

Another fun release of a lost #PS2 game demoed at E3 and never seen again! Rubu Tribe never was released but now you can enjoy it today thanks to me with big help from @yuvi.app doing some coding work! youtu.be/mKUl24K77N4 #gaming #gamingnews #gaming_news

Biohazard: The Episodes was preserved by @yuvi.app! Lost to time until today, this mission-based game was based on Biohazard 3. It appears to be the full game, minus extra characters. We have now preserved at least partial copies of all three keitai-exclusive 3D #Biohazard games!

Another lot another gem..
Today find was a phone loaded with games, and one of them being
“Biohazard the Episodes”.
So far it seems to be working in full, but more testing and processing to come!

R.O.B. - Ride on the Beat!! was preserved by @yuvi.app! Released in 2005 for keitai, this is a 3D rhythm game where you ride a hoverboard and change lanes to the beat of the music. It's pretty fun! The 3D graphics are also quite good for a 2005 keitai game.

I got a bit curious... SMT9 already found the text routine to control location, sizing, width, and more. So I made the text half as small compared to just how it was. Guess this game can be done after all.

Beat Snatcher the other night. I don’t think I’ve ever played a game that’s held up so nicely and honestly shocked me for how good the story is and told for a late 80s game. Honestly had a perfect pace and length. However I’m def craving more.
Glad to have this in my collection

The original i-mode release of #Bomberman 3D was preserved by @yuvi.app! Released in 2004, the game has fully 3D stages with multiple elevations. Its EZweb, Yahoo Keitai, and international J2ME releases have also been preserved to various extents.

Roughly two months ago I preserved Tales of Tactics ~Trial Version~ for iMode!
This is a crowning jewel of the games in my opinion and so happy to have at least recovered the trial version. Since the first chapter is fully playable.

Recovered from an F904i I recently acquired. I had to create a server and recreate the whole Spencer Mansion one scene at a time! The game is 95% complete!

I recovered the first part of a horror adventure series called theresia, from a f904i yesterday.
Super creepy and quite compelling to finish it!
Here is a 10 minute intro to the game.
