Thanks to Cuebus's chipoff dump of the 911T, the trial version of Armored Core Mobile 3 has been preserved! This is the SoftBank Yahoo Keitai version. Preloaded on the 911T, #ArmoredCore Mobile 3's trial lets you play through a few missions. (Video credit: @XLeonier)

DoDonPachi DaiOuJou DX Reco.ver (大往生DX-ﾚｺver.-) was preserved by Yuuku! Only sold on December 30, 2007, this is a score competition variant of DoDonPachi DaiOuJou DX. Given how it was only available for one day, this may be one of the rarest i-mode games preserved so far.

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.

ICYMI, @yuvi.app partially preserved Biohazard: The Operations, a previously-lost Biohazard keitai game! It heavily relied on missing SD card data, but Yuvi painstakingly recreated the data from scratch, resulting in all missions and online leaderboards being functional! (1/2)

Cuebus and @yuvi.app preserved Space Invaders x Pac Man! Available for only a month in 2005, this crossover game was exclusive to i-mode and lost to time until today! The Pac Man ghosts are replaced with Space Invader enemies, among other minor changes.

Biohazard: The Operations 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! We made a partial English patch thanks to @snowyaria.bsky.social, @shentok.com, and myself youtu.be/hC1VyUFzqCA

Yuuku preserved Mushihimesama Gaiden (虫姫さま外伝), a keitai-exclusive spinoff of CAVE's #Mushihimesama series! You walk around and throw bombs at enemies, which is a departure from CAVE's usual bullet hell shooters.

All four chapters of Corpse Party: NewChapter were preserved by Yuuku! Released from 2006 to 2007, it is a keitai-exclusive remake of the original PC-98 game. Despite being canceled before its fifth chapter, this previously-lost game served as a base for future #CorpseParty ports.

The i-mode version of Glory of Valkyrie (ワルキューレの栄光) was preserved by Yuuku! Its Android port had been preserved, but its original keitai release had been lost until today! Earlier this year, we also preserved its keitai-exclusive sequel, The Glory of Valkyrie 2.

This is Wild Land, a keitai game made for the F-04B, a device that can split in two. Utilizing Wii-like motion controls, it's a keitai game like no other! While it was preserved last year, its motion controls can't be properly emulated yet.

The first chapter of Edotan (えどたん) was preserved by 2Soulz! Originally released on keitai before being ported to smartphones, Edotan is a detective visual novel by #Capcom. It takes many elements from #AceAttorney. Edotan received a keitai-exclusive sequel, which remains lost to time.

Chase H.Q. 3D was partially preserved by @yuvi.app last year! Originally released for keitai in 2005, this was a 3D conversion of the original #Taito arcade game. Our i-mode copy is Episode 0, and we also have a trial of the Yahoo Keitai version. The full game still remains lost.

Did you know that Elevator Action received two FPS games on keitai? Released in 2005, Elevator Action Real was a 3D conversion of the original arcade game. Its sequel, Elevator Action Real 2, has you play as a ghost hunter! Both games remain lost to time. Longer gameplays below!

Last year, the trial version of DoDonPachi's i-mode port was preserved. It includes the first stage. The game runs surprisingly well for the hardware it was released on! The DoJa 5.1 SDK has performance issues when multiple sounds play at once, so my gameplay has SFX turned off.

Earlier this year, the i-mode port of Detana!! #Twinbee was preserved by an anonymous user! Due to space constraints, the game was split into two apps. Both apps are preserved. Considering the platform, this is a very good port!

Bomberman: Disney Stitch Edition, a previously-lost #Bomberman spinoff game, was preserved by @unabandonware.bsky.social! This was a Flash game released exclusively for i-mode keitai. It is themed to the Stitch anime series, with power-ups being represented by pineapples and hibiscuses.

Thanks to some lucky keitai junk lots from @yuvi.app, over 60 keitai games were preserved over the past few days! My video has some highlights: - Metal Claw, a Virtual On i-mode clone from 2004 - POP'N BALL, a freeware (?) platformer with cute sprites - Lots of tactics RPGs, like Neo Deserters

The i-mode demo of #FFVII Before Crisis was preserved by Cuebus and @yuvi.app! The demo contains the entirety of Chapter 1. Last year, Kraze preserved the EZweb demo. The i-mode demo contains more features, like save data transfer and functional Materia Camera.

Cuebus has been hard at work figuring out how to chip dump this crazy pinout, which is found on early Sharp i-mode keitai. As you can see, the chip is extremely dense, with a 0.5mm pitch! Thanks to his efforts, the range of undumpable i-mode keitai is gradually decreasing.

"Escape From Being an NEET! Usuko's Job Hunting Labyrinth" was preserved by LNRC. The goal is to navigate to the top of a business building to obtain a job certificate, fighting through employees who want to keep their positions! This is certainly one of the more unique i-mode games to be preserved.

Penta no Tsuri Bōken DX (ペン太の釣冒険DX) was preserved by Penguinstrain! This is a cute fishing game starring Penta, the protagonist of the Antarctic Adventure series. This is the 2004 i-mode version; the non-DX version was released in 2003 and is still lost.

2Soulz preserved Galaga Kai, a previously-lost #Galaga game that was exclusively released for keitai in 2011! It has an arrange mode with stages based on other #Namco arcade games! You can see Xevious and Dig Dug in my footage. The DoJa 5.1 SDK doesn't run this game very smoothly, but it's fun!

2Souls preserved Rockman The Puzzle Battle, a previously-lost #MegaMan keitai game! You clear lines to defeat bosses, gaining special weapons along the way. Originally released in 2011, this is the twelfth Rockman keitai game to be preserved. I've posted a longer gameplay below!

Lost in Blue Mobile: Marina & Riku (LOST in BLUE Mobile まりな＆りく編) was preserved by Penguinstrain! Contrary to its name, the game has an original story and characters! Its gameplay is similar to the Survival Kids Game Boy entries. Such a rare #Konami keitai game, and I'm so happy to see it preserved!

Dragon Ball Racing (trial version) and Naruto Keitai Ninjutsu Taisen were preserved by 2Souls! Both were released exclusively for i-mode keitai. Our copy of #DragonBall Racing is a trial version, so it only has Goku and one map. See my reply for gameplay of the #Naruto i-mode fighting game.

#MetalGear Solid Mobile's SoftBank trial version was preserved by Cuebus! This is the second keitai trial version that has been preserved (the other was for EZweb devices). It runs pretty well, too! The full Western release of this game was preserved by @krzbrew last year.

I visited the NTT DoCoMo History Square! On top of there being tons of keitai on display, there is a large library of DoCoMo catalogs. Some contain information about keitai games! For instance, one page discusses Virtua Fighter 4's connection to i-mode keitai. Great resources!

I visited @gamepresint.bsky.social's headquarters in Tokyo and discussed their i-mode game preservation project! We discussed many things, from dumping procedures to cataloguing phone models. It was very productive, and we now have a clearer direction on how to move forward.

Yuuku preserved Evangelion The Fighting Impact Rebuild, a previously-lost #Evangelion i-mode game! This is a fighting game with little to no documentation online. The spritework is very nice. Every other preserved Evangelion i-mode game is a slot game, so this is a welcome find!

I'm currently visiting Japan for the first time, and I tried 1Seg on my P-01A! This is a digital TV broadcasting service, and these keitai models can still play them back when in range. While we can easily watch TV on our phones nowadays, this must have been novel back in 2005!

I preserved Bomberman Puzzle Special, an i-mode #Bomberman game released in 2008! An expanded version of the original Bomberman Puzzle, it has 600 sokoban puzzles and the ability to create your own levels! You can save up to 10 custom levels. We've already preserved the original Bomberman Puzzle.

I preserved the first half of Valkyrie no Densetsu's i-mode port! Released in 2005, this port of the #Namco arcade original was split into two apps. The game runs better on original hardware. While I also preserved the second half, its app data was missing because it was never launched.

Cuebus preserved the trial version of Friends of Mana, a keitai-exclusive entry in the #Mana series! Chip-dumped from an 811SH, the trial is an opening chapter with some battles. The full game, which featured online multiplayer, was heavily network-dependent and still lost.

Gameplay of "Aka-chan wa Doko Kara Kuru no? Koitsu ~ ban," a preserved #Sega i-mode game. It's a Simon Says minigame derived from the Nintendo DS game of the same name, known as "The Rub Rabbits!" overseas. The i-mode game was a free download to promote the DS game.

Major advancement in i-mode game emulation! In just one month, GuyPerfect created a Yamaha MA-2/3 audio implementation system, allowing us to listen to #Gradius NEO/NEO Imperial's soundtrack as it sounded on original hardware. Both games now have near-perfect sound emulation... (1/2)

This is the N-01B Eternity Pink, designed by Samantha Thavasa, a Japanese fashion brand! This came in my most recent keitai junk lot. While it didn't have any games, it has a very snazzy design! The keypad has numerous lighting patterns, some of which were downloadable.

User Chicken preserved Star Soldier Special (スターソルジャーspecial), an upgraded keitai port of the original Famicom game! This is the 2004 i-mode release. This game was also included in Bomberman Land 3 as an unlockable minigame, albeit hardcoded and not emulated.

User Chicken preserved a partial copy of Tokimeki Memorial's i-mode port, but it isn't playable right now. It is heavily server-reliant, with all of its event scripts being stored on a server. We can only get as far as the game menu. It'll be a steep task to fully preserve it.

Yuvi made a huge breakthrough with preserving FFVII Before Crisis! He was finally able to convert the EZweb demo (all of chapter 1) with our i-mode copy (partial rescue and training modes). EZweb games run on BREW and i-mode games run on DoJa, so this was a major conversion.

Deathsmiles Gaiden Lost Days is a previously-lost CAVE shmup developed exclusively for keitai in 2007. It has two playable characters and 15 missions. The game was preserved last year, and it runs quite well in the DoJa SDK's emulator! Watch a 100% no-hit playthrough here: youtu.be/LoMoxHw6NzY?...

This keitai only had horse race betting apps, but it also had a 10/10 ringtone 🍹

I was interviewed by @gamepresint.bsky.social for its recent English newsletter about the state of Japanese feature phone game preservation! I helped coordinate their initial i-mode efforts in 2021, and I've continued to work closely with them since. Read it here: www.gamepres.org/en/media/con...

Hello everyone! It's been a while. :) We would like to thank Time Extension for their recent article highlighting the current financial state of the GPS. We would like to expand on it somewhat and respond to some of the comments left by readers. www.timeextension.com/features/we-...

The #KingdomHearts Mobile i-mode minigames now have their online functionality restored, thanks to @yuvi.app! Each minigame has an online leaderboard, and you can earn Munny to spend in KH Avatar Kingdom. However, our partial copy of Avatar Kingdom isn't functional yet... (1/2)

At TGS 2001, DoCoMo's i-mode service was presented alongside Xbox, PS2, and N64 as the 4 big game platforms. It shows the prevalence of i-mode and other keitai games during this time. More than just a fad, they were precursors to modern mobile games as we know them.

Our friends at @hitsave.org did a new podcast episode on keitai game preservation! It features me, @yuvi.app, @xershadowtail.bsky.social, and @unabandonware.bsky.social! We discuss SquirrelJME, restoring FF7 Before Crisis, and even the burnt Layton i-mode phone. Listen here: tinyurl.com/4z39f7ta

Through Cuebus's chip-off, the D901i has been dumped for the first time! In doing so, he preserved Cubic Invaders and Densha de GO! Going Round in Yamanote Line. The former is a 3D rendition of Space Invaders. The latter (second half of video) utilized the phone's sliding keypad to open/close doors!

#MonsterHunter i now has an English patch, courtesy of Grender and Yuwika! They translated thousands of lines of text and even set up a server to host assets that weren't stored locally. The game was only preserved last month, so this was a diligent effort! Link in the replies.

Today is the 25th anniversary of Mega Man Legends 2, first released in Japan on April 20th, 2000. Although a true sequel may still be far off, Rockman DASH 5 Islands—a fully-realized spinoff, previously exclusive in Japan—is now playable in English. www.rockman-corner.com/2025/03/rock...

Beat-up keitai usually have good games on them, but this one is something else entirely! I'm sending it to Cuebus so he can attempt a chip-dump. We have no idea what's on it. Fun fact, this phone is the N701iECO, which has a biodegradable shell! That's why it's crumbling apart.
