Happy to have helped preserve this unreleased PS2 game, “Rubu Tribe”.
This game is certainly interesting, and I could have seen it doing well if it had been released back in the day.
This contains multiple compiled levels and some test levels as well.

Another fun release of a lost #PS2 game demoed at E3 and never seen again! Rubu Tribe never was released but now you can enjoy it today thanks to me with big help from @yuvi.app doing some coding work! youtu.be/mKUl24K77N4 #gaming #gamingnews #gaming_news

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!

Another lot another gem..
Today find was a phone loaded with games, and one of them being
“Biohazard the Episodes”.
So far it seems to be working in full, but more testing and processing to come!

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.

I got a bit curious... SMT9 already found the text routine to control location, sizing, width, and more. So I made the text half as small compared to just how it was. Guess this game can be done after all.

Beat Snatcher the other night. I don’t think I’ve ever played a game that’s held up so nicely and honestly shocked me for how good the story is and told for a late 80s game. Honestly had a perfect pace and length. However I’m def craving more.
Glad to have this in my collection

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.

Roughly two months ago I preserved Tales of Tactics ~Trial Version~ for iMode!
This is a crowning jewel of the games in my opinion and so happy to have at least recovered the trial version. Since the first chapter is fully playable.

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)

Biohazard: The Operations
Recovered from an F904i I recently acquired. I had to create a server and recreate the whole Spencer Mansion one scene at a time! The game is 95% complete!
We made a partial English patch thanks to @snowyaria.bsky.social, @shentok.com, and myself

I recovered the first part of a horror adventure series called theresia, from a f904i yesterday.
Super creepy and quite compelling to finish it!
Here is a 10 minute intro to the game.

(1/8) It's time for another English translation patch release for the FM Towns!
This time, it's Queen Soft's "Gambler: Queens Cup", part graphic adventure romance sim, part horse betting sim (yes, you read that correctly).

Two days ago, I found a phone with the Before Crisis Trial version on it, and well, with the help of many members of the KeitaiWiki team. We have preserved that and made it available to play today! This is mostly the same as the BREW version, but a lot easier to play.

Just about a year ago I joined the Keitai Wiki team to help figure out Before Crisis FF7, and well, we've done so much since then. So I made a video kind of going over everything we have recovered since then. There is still so much to do, so wait a bit.

Today I acquired a dev unit 3DS with 2 Dev carts,
I know the contents of one, but the other is unknown. I will dump and preserve them :)

Another breakthrough! I’ve finished the Before Crisis Sprite Extractor. The custom format was a bit tricky, but it now extracts characters, enemies, palettes, animation layers, frames, and all 3D arrays.

Well, it happened. I just recovered another lost Tales of Mobile game, Tales of Tactics!
I cannot believe I have the honor of saying I've recovered almost every lost Tales of Mobile Keitai game at this point. Check out footage here.

I preserved Bomberman Puzzle Special, an i-mode #Bomberman game released in 2008! An expanded version of the original Bomberman Puzzle, it has 600 sokoban puzzles and the ability to create your own levels! You can save up to 10 custom levels. We've already preserved the original Bomberman Puzzle.

Major advancement in i-mode game emulation! In just one month, GuyPerfect created a Yamaha MA-2/3 audio implementation system, allowing us to listen to #Gradius NEO/NEO Imperial's soundtrack as it sounded on original hardware. Both games now have near-perfect sound emulation... (1/2)

I finally did it... What a tremendous task this was. But I fully converted the W51h build of Before Crisis to Doja code. Some things to still fix, but wow, seeing this just makes me so damn happy.
