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!

It just dawned on me that this game is literally this gif

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 (ドドンプチ零) and a trial version of DoDonPuchi (ドドンプチ)! 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.

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)

Dokodemo Dodgeball Fantasia (どこでもドッジボ−ルファンタジア) 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.

Cuebus and I preserved Konami Wai Wai Sōkoban (コナミワイワイ倉庫番), 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.

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.

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.
