(I get destroyed by Shadow)

My Sonic 7 Narabe gameplay:

Two previously-lost #Sonic keitai minigames and the original i-mode version of Sonic Jump were preserved by @yuvi.app! The minigames are Sonic 7 Narabe and Sonic Reversi Hyper. Sonic Jump was later released for Western phones, but the original keitai version was lost until today.

Yep! Released only on Japanese feature phones, lost to time until we preserved it two years ago. And it's actually good!

You can play this English patch via Keitai World Launcher!

Thanks to Muttvil and Penguinstrain, Rockman Tennis now has an English patch! The game used many image files, so Muttvil did a great job with their English conversions. Partake in tournaments and buy upgrades in the shop! Can you unlock the secret character?

I have a positive update on this! Yuvi preserved the full version last year, but it had a network check. Today, Yuvi went through the effort of removing that network check, so now the full version of Metal Gear's i-mode port is preserved and playable!

Last year, Xyz preserved the trial version of Metal Gear's i-mode port! Released in 2004, this keitai port has an easy mode and a different script than the MSX2 version. It also served as the basis for the game's rerelease in Metal Gear Solid 3 Subsistence!

Last year, Yuvi preserved the trial version of Dragon Ball Battle Heroes! Originally released for i-mode keitai in 2009, this is a fighting game with three CPU opponents. The trial version includes Point Battle, where you compete to get the most KOs within a time limit.

You can view all our preserved chara-den via the Chara-Den tab in Keitai World Launcher!

Earlier this year, Yuvi preserved a chara-den of Reid from Tales of Eternia! Chara-den were avatars you could use for videophone calls on i-mode keitai. Each number on the keypad corresponds to a different emotion! Most chara-den are 2D, but some use 3D models, like this one.

Here's a side-by-side comparison of the LCD game and the keitai port. Quite faithful, I must say 😆

A keitai game that's a port of... a Casio LCD calculator game?! Preserved last year by Yuvi, "Boxing Game" was developed by G-MODE and originally released for i-mode devices in 2001. Our preserved version, which has better graphics, dates to 2004.

Pink Sweets Gaiden: Taisen! Rose Sisters (ピンクスゥイーツ外伝 対戦！ローズシスターズ) was preserved by @yuvi.app last year! Previously lost to time, this was CAVE's keitai-exclusive prequel spinoff to its Pink Sweets schmup. The game also let you fight other players via online rankings.

Today, the #Sega Alarm Clock Sound Sample was preserved! This app is dated to 2004, and it let you download Sega alarm melodies. There was even an online ranking of the most popular melodies! Unfortunately, our copy doesn't have any saved melodies, but you can browse the app.

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.

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.

I finally beat #Rockman: The Puzzle Battle! This was preserved last year. The Wily bosses are brutally difficult, but the music remixes are nice. I'm playing on the English patch created by Penguinstrain, Yuvi, and Muttvil. Full video footage can be found in the replies!

Our efforts target all keitai games; DoCoMo just happens to be the carrier with the most archived games. One of our team members, Cuebus, has put a lot of work into chip-dumping Unabandonware's J-Phone devices. We'd love to see your small archive! You can reach out via @keitaiarchive.bsky.social.

It's definitely coming back next year, so don't worry!

Here's a comparison of how the games look with Irdkwia's plugin vs original hardware.

Dokodemo Chocobo 1 and 2 are now playable! Released in 2002, these are standby keitai apps and dungeon crawlers! Cuebus preserved them last year. They utilize Mitsubishi's proprietary Z3D graphics engine. The original Z3D plugin is lost, but Irdkwia recreated it with Mesa 3D!

#MAGFest: I've spent 2.5 years preserving games from Japanese feature phones with a small online group, mostly isolated, trying to convince people that these games are important. It feels like, finally, people understand. Words cannot describe how great it feels. Thank you for the opportunity ❤️

By a big margin...
Fire Man is the only problem in Puzzle Battle... in Mickman 39, the whole game is the problem! 🤣

This game took years off my life and it will take years off yours too! Might be the hardest game on display...

The i-mode website, which hosted i-mode game storefronts, shut down in 2021. The remaining pieces of the i-mode service don't pertain to games, so the total shutdown in April won't impact them.
