In a surprise turn of events, Rockman Poker was preserved by Penguinstrain! This originated from GoodTofuFriday's dump of Midori's keitai, the same dump that had copies of Rockman.EXE PoN/LoN and Rockman DASH 5 Islands. Nearly three years ago, we overlooked this Flash file.

Yeah, it's crazy! There were two separate apps for the X and Zero campaigns, both relying on SD card data. We found the Zero version, but since its phone didn't have the SD card, the app was an empty shell.

A trial version of #Rockman X2's Yahoo Keitai port was preserved by @unabandonware.bsky.social! It only contains the opening stage. Hopefully we'll find the full game in the future! X3 and X4's keitai ports remain lost to time. Thanks to NaoyaShinota for patching this game's network check.

The i-mode and Yahoo Keitai ports of Rockman 3 were preserved by Xyz and LNRC! Our i-mode copy dates to 2005 and has 攻略モード, which lowers the game's difficulty. Our Yahoo Keitai copy (this post's video) is an updated release. Later iOS/Android ports of Rockman 3 appear to be based on it.

The first third of Gokujō Parodius's i-mode port was preserved by an anonymous user! This features the game's first three stages. The game occasionally has audio issues in OpenDoja, but this should be resolved in due time.

Jaseiken Necromancer 2 (邪聖剣ネクロマンサー2) was preserved by an anonymous user! This is a keitai sequel to Jaseiken Necromancer, a PC Engine RPG. It was later rereleased on DSiWare as "Jaseiken Necromancer: Nightmare Reborn." The original keitai version was lost until today! The battle music is so good...

I'm so grateful that Sousi is doing this; Before Crisis was so network dependent that video footage is paramount to recreating the game. Fun fact, the in-game location where you fight Jade Weapon corresponded to your IRL location in Japan! Ex. Hokkaido -> Icicle Inn www.youtube.com/playlist?lis...

As keitai game preservationists continue to work away at preserving Before Crisis FFVII, user Sousi has been uploading his own Before Crisis gameplay recordings. This includes our first ever video footage of Weapon D Mode (postgame Jade Weapon superboss) and Free Mode! youtu.be/wDrTycFumfU?...

This is probably the biggest update to Keitai World Launcher to date! The application is so much easier to navigate, on top of the new integrations with Keitai Wiki. It's amazing to see how far keitai game accessibility has come since KWL launched in March 2025. Huge props to @yuvi.app!

Breath of Fire: Ryū no Tsurishi (ブレスオブファイア竜の釣り師) was preserved by SPC! This was a keitai-exclusive Breath of Fire fishing minigame, lost to time until today. By trading in your fish, you can purchase different lures and fishing gear!

After four days of bruteforcing and spending over $900, the FULL version of FFVII Dirge of Cerberus Lost Episode has been preserved by @yuvi.app! The game's SD card data, which it fully relies on, remained encrypted until now. Despite being 9MB, the game contains cutscenes and voice acting.

I was unfortunately unable to make it to Save the Games this year, but I'm so happy that @unabandonware.bsky.social is continuing the keitai game representation! Recording videos and preserving supplementary game info is so important when server-based games become unplayable.

For sure! KDDI contents have just been much harder to extract compared to DoCoMo models. But we probably have found some KDDI ringtones because I remember there being discussion on its audio format. @unabandonware.bsky.social might know.

RockmanCosmo @rockmancosmo.bsky.social · 17/07/2026

Keitai Archive has uploaded its collection of i-mode ringtones to the Internet Archive, which include a few ringtones officially distributed by #Nintendo! These were likely lost to time until now. There are also a lot of great fanmade ringtone arrangements of game/anime songs.

Rozen Maiden ~Fräulein Rose~ (ローゼンメイデン~薔薇乙女~) was preserved by SPC! This is a visual-novel adaptation of the #RozenMaiden anime series, exclusively released for keitai in 2005. There were 10 episodes in total; our copy is the first episode.

RockmanCosmo @rockmancosmo.bsky.social · 08/07/2026

This news also feels a bit ironic: the majority of the original Before Crisis was lost because of its unprecedented reliance on keitai game servers. Now, this "reincarnated" version of Before Crisis will face the same fate, albeit in the context of gacha gaming's lifecycle. (2/2)

RockmanCosmo @rockmancosmo.bsky.social · 08/07/2026

It saddens me that Before Crisis's story is being added right before Ever Crisis's EOS, it deserves more time to be experienced. The original Before Crisis's keitai servers lasted for 14 years, with chapters being released nearly monthly for three years. The preservation effort continues... (1/2)

Here's an archived version of Konami's webpage on HA-CO. There doesn't seem to be much else archived about it, so gameplay videos are appreciated! web.archive.org/web/20070227...

RockmanCosmo @rockmancosmo.bsky.social · 07/07/2026

User SPC preserved HA-CO, a previously-lost #Konami puzzle game made exclusively for keitai! Released in 2004, you push boxes and avoid enemies to reach the stage's goal in as few steps as possible. There are 100 stages total. There's also a model viewer for character models!

Tales of Quiz (テイルズオブクイズ) and Tales of Wonder Casino (テイルズオブワンダーカジノ) were preserved by an anonymous user! Our copy of Quiz contains quizzes about Tales of Phantasia, Destiny 2, and Abyss. Wonder Casino has a variety of Tales-themed casino minigames. See my reply below for Quiz's gameplay!

Keitai World Launcher is the most straightforward way to access preserved keitai games. When starting Tales of Wahrheit, select "no voice" on startup (the game immediately tries to download voice data that doesn't exist). keitaiarchive.org/downloads.html

Tales of Wahrheit was partially preserved by an anonymous user! This game heavily relied on server data, so you can only load into the existing save files, and the amount of playable data is pretty small. Nonetheless, it's great that some parts remain playable.

Alcohol, Souvenirs, and My Insufferable Wife (酒と土産と鬼嫁と私) is a humorous keitai game that was preserved a while back. The goal is to collect presents while avoiding alcohol. Consuming alcohol increases your drunkenness meter, and once you get too drunk, it's game over...

RockmanCosmo @rockmancosmo.bsky.social · 13/06/2026

That's a good question! I keep them in a box, using good-condition phones for demonstration purposes. Preservationist @unabandonware.bsky.social has hundreds of phones; sometimes they wipe the data and sell them to people who collect keitai at large.

A new partial copy of Before Crisis FFVII was preserved by NaoyaShinota! This copy contains Turk data for Cissnei, as well as a battle map and sprites for Weapon D Mode (postgame superboss mode). Now we preserved four Turks: Rod, Gun (Male), Nunchuck, and Shuriken (aka Cissnei).

User MeaxyKusama has connected an i-mode keitai to their homebrew phone network, Mizuki Mobile! This allows them to connect to i-mode webpages and download i-appli. This opens up the possibility of playing i-mode games on a wider range of original hardware, including multiplayer games!

Gameplay of Galaga Kai, a keitai game that was preserved last year! Its Arrange Mode features stages and boss battles based on #Namco properties. You can see quite a few in this video, including a Mappy boss! Thanks to the OpenDoja reimplementation, this game now runs with no performance issues.

Clarisse la Sorcière (魔法使いクラリス) was preserved by WN3DL! Released in 2002 by G-MODE for i-mode keitai, this is an isometric shooter starring a sorceress on a broomstick. Survive for as long as possible and aim for an A rank!

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!

So far, all G-MODE releases are completely offline. However, they've haven't rereleased a server-dependent title yet. I'd imagine they'd make all the content available locally, like some offline gacha games. But as for online keitai game functionality (i.e. Before Crisis), it remains to be seen.

031

RockmanCosmo @rockmancosmo.bsky.social · 16/04/2026

Supporting G-MODE releases is important because many keitai games, including the Tales keitai games, are heavily server-reliant. A G-MODE rerelease is the only way those can be experienced. We're also hopeful that this encourages other publishers rerelease their keitai games!
