Sonic Speed DX, a previously-lost #Sonic keitai card minigame, was preserved by @unabandonware.bsky.social and Cuebus! In addition to CPUs, the game has local multiplayer... you just turn your phone sideways. Playing the game earns you rings, which could be spent on phone wallpapers.

ICYMI, @yuvi.app released ReMEXA, an SDK reimplementation for J-PHONE, Vodafone, and SoftBank keitai games! These were competitors to i-mode games. They're finally accessible on Windows, Linux, and Mac. See my video for some featured games! An Android version is in the works too, so stay tuned...

Tokimeki Memorial Girl's Side Puzzle-Dama (ときめきメモリアル Girl's Side ぱずるだま) was preserved last year! This was a keitai-exclusive Taisen Puzzle-Dama spinoff. You can choose 14 different attack patterns, and winning 10 matches in a row gives you a wallpaper image.

Footage of Yumeria Chibi (ゆめりあちび), a 3D i-mode application based on Namco's PS2 game, Yumeria. Released in 2004, the application lets you view five characters from the game, akin to a 3D model viewer. It was preserved about two years ago.

Gameplay of Banchō Table Tennis (番長卓球), a preserved i-mode game. It's a table tennis game based on the Osu! Banchō series of pachislot games. As such, it features slot machine and quick time event mechanics. The music is also quite good!

This is great news! As some may recall, Pied Piper was found last year. In accordance with Keitai Archive's policies on commercially-available games, it's been removed from Keitai World Launcher. An English translation was underway, and it's still continuing. Please support the official release!

Keitai World Launcher now includes a "903iHP" sound setting for the DoJa/Star SDK's emulator! With this setting, you get more accurate 903i audio without the performance hit. Audio stuttering has also been greatly reduced! It only occurs if the game drops frames. See my video to hear the difference!

An anonymous user preserved Taisen Puyo Puyo Tsu DX, an i-mode #PuyoPuyo game with real-time online multiplayer! Thanks to @yuvi.app, this online battling functionality is fully functional! Create a room or battle random opponents.

The i-mode port of Puyo Puyo Sun was preserved by an anonymous user! Released in 2006, this version of the game only features Arle's story.

A preloaded trial version of Darius Wide was preserved by WN3DL and Cuebus! This was a keitai port of Darius for devices that supported horizontal screen orientations. This copy was preloaded on the 920SH, which was a Yahoo Keitai (SoftBank) device. (Gameplay credit to Leonierx)

The original i-mode port of Cleopatra Fortune was preserved by @wowmd.bsky.social and Cuebus! This was released by Taito in 2002, making it a very early keitai game. It was later updated with improved visuals.

Last year, the Aegis and Teddie machi-chara was preserved! Machi-charas were home screen avatars on DoCoMo keitai. They walk around the screen, offering assistance or playing cute animations. For instance, Aegis and Teddie would let you know if you got new mail!

Happy one year anniversary to the Rockman DASH 5 Islands English patch! Lost to time until 2024, this game nails the Mega Man Legends series' style and character writing. If you want to experience one more adventure with the Legends cast, I encourage you to check it out!

A partial copy of Tekken 2's i-mode port was preserved by @yuvi.app! Released in 2006, our copy appears to have been tailored to Sony Ericsson i-mode keitai. It relied on SD card data that we don't have, so only simple mode is playable.

The original i-mode release of Bomberman Kart Special was preserved by SJ2 and Cuebus! You can play as six characters and race on six tracks. This was released internationally in 2006, but the original keitai version was lost to time until today.

Keitai World Launcher has been updated to Ver. B0.8.4! ✅ Tons of code optimizations to make the program open faster and load more efficiently ✅ Adding custom apps doesn't require a restart ✅ Better memory management (less disk read/writes) ✅ Added option to edit appli information directly in KWL

I just created an OpenGL hardware renderer for STAR keitai emulator. No longer will heavy 3D games run badly. Minna no Golf Mobile 3 goes from like 4 FPS to a locked 30 FPS. All with proper 3D character rendering and texture loading. Plus internal resolution scaling.

I went on the Video Game History Hour podcast with @unabandonware.bsky.social! It's a great overview of keitai game preservation, from the games to preservation challenges. I hope you enjoy! Thank you to @philsalv.bsky.social for having us on. Listen here: gamehistory.org/episode-152-...

Today, @unabandonware.bsky.social and @robocami.bsky.social preserved some Toro Inoue i-mode media! These could be attached to emails or be used as wallpapers. A second image is below!

This is "Kirin: Let's Supporter" (キリンLet'sサポーター), a licensed i-mode game that was preserved last year. It appears to have been released to coincide with the 2006 Kirin Cup Soccer tournament. It's a rhythm game, where you try to match the spectators' moves! I clearly need to work on my moves...

Thanks to Leonierx, the second and third stages of Star Devastator are now playable! It turns out the trial contains the first half of the full game. For a 3D keitai game in 2003, this one pushed the limit. Hopefully we'll find the rest of the stages one day! I've posted a longer gameplay below.

Online features for "Pink Sweets Gaiden: Taisen! Rose Sisters" have been revived, thanks to @yuvi.app! This keitai-exclusive Pink Sweets spinoff let you upload ghost data and fight against other players in ranked VS battles. Earn points and upgrade your character!

Earlier this week, @yuvi.app preserved Mappy de Puzzle, as well as several other previously-lost #Namco i-mode ports from the early 2000s! Mappy de Puzzle was released exclusively for keitai in 2003. You guide a set of Meowkies through a maze. It's really charming!

Yesterday, Yuvi preserved a Klonoa chara-den! This is an avatar you could use for videophone calls on i-mode keitai. Each number on the keypad corresponds to a different emotion!

The trial version of Star Devastator (スターデバステーター), a keitai-exclusive #Konami game, was preserved by @yuvi.app! Released in 2003, this was an ambitious 3D rail shooter that was only released for i-mode devices. This may have been one of the earliest 3D keitai games.

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.

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.

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.

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.

Keitai World Launcher has been updated to Ver. B0.8.1! ✅ Added privacy policy acceptance ✅ Added M7 audio for KEmulator ✅ Added rotated dialpad option for landscape appli ✅ Packaged emus updated ✅ Updated default emulators ✅ Code optimizations

Keitai World Launcher has been updated to Ver. B0.8! ✅ New home screen with five random featured games and a list of recent additions ✅ Redirection of SIMPLE100 URLs

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!

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 ❤️

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!

2025 has been an incredible year for keitai game preservation! Your continued support for this small part of gaming history has meant the world to me, so thank you! Here are some year-end preservation statistics from Keitai World Launcher. Here's to an amazing 2026!

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).

The complete i-mode port of Mushihimesama Futari was preserved earlier this year by @YuviApp! Like the rest of CAVE's i-mode games, it runs surprisingly well on the limited hardware. My longer gameplay video can be found in the replies.

The 2005 i-mode port of IQ Intelligent Cube was preserved by NaoyaShinota! The game was originally released by Sony for the first PlayStation. This is a pretty faithful port to the original game, minus the orchestral soundtrack.

Gameplay of Moba UFO, a 3D racing i-mode game that's now playable thanks to Yuvi's Mobage server revival! It tries (and fails) to save ghost data after a race. This and other online functionality will be revived later. It's amazing to see how far we've come with preserving server-based i-mode games.

Gameplay of Ayane-chan Panic, an i-mode freeware game from 2003! Preserved by Cuebus last week, it has some impressive platforming and wall climbing mechanics! It's always fun to highlight these smaller, more overlooked pieces of keitai gaming history.

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.
