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!

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

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.

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.

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.

Just finished 10 hours of programming on Before Crisis. I was able to finish a big amount of database work and finish multiple other features of the game. For example, you can now properly start a new game, create an account, add friends, and much more.

Interesting.. I had inadvertently found a way how to put a SoftBank Samsung Keitai into test mode or something of the likes.
Not 100% sure what this does for us yet. But it’s a find. You can do this by shorting the thermistor to + and on boot it shows this.

Happy to have dumped a phone that contained Three Dragon Ball games.
- Dragon Ball Wars
- Dragon Ball RPG Trial
- Dragon Ball RPG Full Version
The Dragon Ball RPG trial version is available now, as I work on reverse engineering the network for the full version.

We do have everything as of when this phone last played SD Gundam. This app was last updated on Jan 28, 2010. This includes roughly 24 Scenario Missions, and 36 Quest. Spanning across Gundam UC0079, and ZETA
It will be available to play soon :D

After bruteforcing the SD-Card private key, reverse engineering file formats, and building a network server, we now have a fully working SD Gundam G Generations Mobile !
Currently investigating if we’ve got the entire game or just a partial build. Stay tuned!
Here's small peak.

Here we are Brute forcing a decryption key for a SD Card to save Keitai games. Oh how I love to have my GPU working 12 days straight to find a single key :D
What we do for the love of preservation.

The contents of the SD card can be read by pretty much any machine. But obviously they are stored compressed. After making a backup and getting to the GPE which is the executable, I was able to find in the game code where it checks for serial license and other information.

I recently got a GP2X WIZ, and one of its few exclusive games, Redemption: Liar. Since this company no longer exists, I wanted a way to play my copy of the game on a normal SD card, so I don't have to put strain on a rare SD card.

Here is one of the 17 maps fully extracted and pieced together from Before Crisis Chapter 1.
Honestly these look pretty good for the day I’d say. They especially made really good use of limited tile space to keep the data usage low.

This screenshot might not make much sense to most (and yes, it’s a bit broken), but it’s a rare feature of Before Crisis you’ve probably never seen or heard of: the online PVP matchmaking Battle Square. Almost have it working again!

Back with some Before Crisis!
This time I finally figured out how to get into the Golden Saucer and play some Arm Wrestling! Unfortunately we are missing data for the other 2 mini games. Still a long road ahead, but happy to be here!
