It's our pleasure! Seeing people discover and experience these games for the first time is one reason why I love being a game preservationist. Greater accessibility is at the heart of preserving this history.

Thanks to @aid1043.bsky.social and Penguinstrain, Columns Jewel has an English patch! This was a #Columns keitai game that was preserved last year. It has a story mode, where Sana travels back in time after wearing a mysterious bracelet. There's also a puzzle mode with 40 puzzles!

We've found plenty of keitai freeware games, but "Super Merio" has shown up on multiple devices. As the name suggests, it's a Mario clone. Released in 2001, it's one of the earliest pieces of keitai freeware that we've preserved. It has two sequels (?) and even a spinoff called "Dr. Merio."

Gameplay of THE Skydiving, a keitai game released in 2009. This was preserved by LNRC earlier this month. You try to skydive to the ground as fast as possible, dodging missiles and passing through fellow skydivers in the process!

Cuebus preserved DoDonPuchi Zero (ใƒ‰ใƒ‰ใƒณใƒ—ใƒ้›ถ) and a trial version of DoDonPuchi (ใƒ‰ใƒ‰ใƒณใƒ—ใƒ)! Released in 2003, DoDonPuchi Zero was CAVE's first original shooter for keitai. Both were lost to time until now! DoDonPuchi Zero's soundtrack was composed by Namiki Manabu.

We currently use the DoJa SDK, an emulator developed by DoCoMo. It has a lot of issues with performance and emulating sounds, so projects like @squirreljme.cc aim to replace it eventually. Keitai World Launcher has the DoJa SDK bundled in it: keitaiarchive.org/downloads.html

@borman.bsky.social it didn't take us long to find a copy of the last remaining keitai sequel to The Missions!

Of the four 3D Biohazard feature phone games, only one (The Missions) was released internationally. Here's the preservation status of its keitai sequels:
- The Stories (trial version)
- The Episodes (full game minus extra characters)
- The Operations (partial, pieced together)

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!

ICYMI, after 7 months of work, @aid1043.bsky.social finished their English translation patch for all eight Kingdom Hearts Mobile keitai minigames! Preserved last year, this patch even contains recreations of cut content, like bonus puzzles and downloadable cards! (Video credit to Aid)

It was for a score attack competition, I believe. And yes, all preserved keitai games are playable through Keitai World Launcher.

After 7 months of work, my latest project: a full English patch of Kingdom Hearts Mobile! You can play all 8 of these previously-lost mini-games, in English for the first time.

There's puzzle games, card games, rhythm games, and more, and even canon lore!

Dokodemo Dodgeball Fantasia (ใฉใ“ใงใ‚‚ใƒ‰ใƒƒใ‚ธใƒœโˆ’ใƒซใƒ•ใ‚กใƒณใ‚ฟใ‚ธใ‚ข) was a dodgeball RPG released for keitai in 2006. Yes, you read that right! It's got a coming-of-age story and a real time battle system. We preserved this game earlier this year, and it's incredibly unique.

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.

Finally, Keitai Archive has a comprehensive FAQ with further clarification about our mission, including our non-profit intentions (we do not accept monetary donations) and forms for takedown requests. Thank you for continuing to support keitai game preservation! (6/6)

Fourth, Keitai Wiki isn't going anywhere! It has always been for documenting game information, while Keitai Archive is more focused on the technical side of keitai game preservation. The Keitai Wiki Discord server has been renamed "Keitai World" to encompass both entities. (5/6)

Third, Keitai Archive will not distribute commercially-available keitai games, such as games that are on G-MODE Archives. This is to support publishers who rerelease their keitai games, as well as to avoid possible litigation from said publishers. (4/6)

Second, Keitai Archive will have a quarterly-updating archive.org repo of abandonware keitai games and media. Newly-preserved games will still be accessible through Keitai World Launcher. You can find this repo here: archive.org/details/@kei... (3/6)

First, Keitai Archive aims to have a GitHub repo for the tools used in keitai game preservation work. This includes file system extraction, file conversion, and other tools to access media on Japanese feature phones. This repo is a WIP, but we are actively working on it. (2/6)

I understand your concerns, and I agree that supporting G-MODE is incredibly important. For that reason, Keitai Archive has a policy to never distribute any game that G-MODE has already rereleased. This saves us from potential legal action, and it encourages people to support the official releases.

Cuebus and I preserved Konami Wai Wai Sลkoban (ใ‚ณใƒŠใƒŸใƒฏใ‚คใƒฏใ‚คๅ€‰ๅบซ็•ช), a keitai-exclusive #Konami puzzle game! It features characters from various Konami games. A year ago, I found the phone that this game originated on, but the screen was broken. Cuebus managed to dump it today.

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.
