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.

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!

This is great news! As some may recall, Pied Piper was found last year. In accordance with Keitai Archive's policies on commercially-available games, it's been removed from Keitai World Launcher. An English translation was underway, and it's still continuing. Please support the official release!

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...

Thanks for the mention! Thankfully, that game is preloaded on that phone model, so we've already preserved it. But uses steganography to hide code inside gif files, so it's a pain to get emulated. In that sense, it's easier to play it on original hardware.

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.
