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.

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!

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.

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)

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...

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.

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!

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.

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.

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...

RockmanCosmo @rockmancosmo.bsky.social · 12/03/2026

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.

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.

RockmanCosmo @rockmancosmo.bsky.social · 26/02/2026

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!
