Support for Softbank/Yahoo! Keitai APIs

[SergioFLS]

There recently have been some games dumped from Japanese phones that implement those APIs. I did some light digging through a single game (Puyo Puyo!/15th anniversary) code and found that it seems to be just MIDP with some imports of com.j_phone.

I also tried that Puyo Puyo game with a recent commit but so far I only got a black screen.

JL-Mod can run the Puyo game with some heavy graphical bugs, along with Tetris DJ. I thought that was worth mentioning as that codebase is under the Apache 2.0 license which should be compatible with FreeJ2ME's GPLv3.

That's something i've been discussing with @TwoSpacesSG on discord. From all the keitai vendor implementations out there, softbank does seem the easiest to implement (especially compared to DoJa's later API revisions for example), i just have a big list of TODOs at the moment so i can't really focus on this, or FreeJ2ME in general.

It depends on which game it is, some of those are 2D games that are fully playable in JL-Mod, others are 3D games using OpenGL APIs like Klonoa, which aren't even fully implemented in JL-Mod (Klonoa works with graphical bugs, and is not beatable). Also there's the elephant in the room that is SMAF (.mmf music) and MFi (.mld music).

A few years ago, I learned about an example of porting a Korean SKT JAVA game to J2ME, which involved SMAF_MMF to MIDI and SMAF_MMF copyright information removal. I don't know if this will be helpful.
