Just tap on the screen and see how taps are handled and strokes are calculated into bezier control points. This application serves no other purpose that to show the touch screen’s diagnostics.

Ruben Nunez has just built a new way of writing text of variable or fixed width in this new engine. It may not be THE fastest but it gets the job done nicely and includes source.

Thanks to http://www.dcemu.co.uk for that one as well.

Kay Hornig has released a chess game for GBA.

Here are his release notes:

After a while developing I’m proud to present my first public project called chessyka.
It is a chessgame. The main goal was not to made the next award winning chessgame. I just wanted to learn developing for the gba and I learn better if there is a real application as a playground.
Now this is the result of my study.

The AI use alpha-beta-search, 0x88 and bitfield representation of the board, hashing with zobrist keys and moveordering. There is an opening book included, but currently this is only a proof of concept and contain only some minor variants of the french defense. A special feature is the possibility to enter a custom position. Although there is only a very simple check for plausibility!
chessyka is aware of all chess rules, including “en passant”, castle, 50-moves-draw and 3x-repetition-draw.

Currently only the english language and basic undo of moves are activated. The multilanguage menu (english, german and espanol) and the advanced undo/redo feature are disabled.

There are some missing features e.g.: permanent brain, search depth extensions and an opening book which is worth the name. If I find the time and motivation I will try to add more of them.

I suggest the level 4 for the AI. Lower is probably to weak and higher needs to much time. A level is a combination of time and search depth. On level 4 chessyka will search at depth 4 (plys) but uses at maximum 2 minutes per ply (average). Which means it will use a part of the spared time from previous moves (e.g. from using the openening book). On level 5 it use 3 minutes per ply average. If you can afford this, it is obvious better.

Maybe later I also present the sourcecode, but not at the moment. chessyka was completely developed by myself. The same applies to the artwork. Only the charset was borrowed from auby.no with his kind permission.
For developing I used the DevkitPro toolchain, the tonclib and “Visual Studio 2003 standard” as an editor.
I want to thank the whole gba homebrew community. Especially I want to thank (in no particular order) Tepples, Cearn and Wintermute!
chessyka was succesfull tested with no$gba (thanks to Martin Korth), “VisualBoy Advance” and of course on real devices: GBASP and NDS lite. For the real devices I used the “EZF advance”, GBAMP v2 CF and Supercard mini SD.

!! Attention !!
chessyka is for evaluation purposes only! Use it at your own risk. There is no warranty, expressed or implied. I’m not responsible for any damage as a result of the usage of chessyka. You are allowed to use and copy the game only in a private environment. You are not allowed to use it on commercial base! With the download you accept this terms of use!

Tyrian is a computer game developed by Eclipse Productions (later named World Tree Games) and published in 1995 by Epic MegaGames.

The game was officially released as freeware in 2004, and the graphics have been made available under an open license in April 2007.

More Information here: http://en.wikipedia.org/wiki/Tyrian_(computer_game)

Now it turned up into Open Tyrian, since it’s been re-implemented to use SDL (check project here: http://code.google.com/p/opentyrian/ )

Kalimerou ported the engine to the GP2x, but you still need the original game files.

NIGathans has released a final of his game Shootuh. The authors PSP has been stolen, so he is releasing what he is having. Thanks to cid2mizard from http://www.dev-fr.org for the news.

Changes:

* Fixed bug causing the enemy to spawn above the slow-mo meter off of the screen.
* Added a “Kill Streak” counter which counts how ever many enemies you kill before you die.
* Added an increasing difficulty based on the kill streak, every 15 kills in a row the difficulty will increase.
* Added more slow-mo power ups (I never got a chance to actually randomize this so it will always appear in the same place.)
* Fixed bug causing your bullets to home on enemies even if its paused.
* Fixed background image so the shrinking is more noticeable.
* Added a secret cheat menu. To access make sure you are in the main menu, whether you just started the game or if you paused it and pressed triangle, and press these following buttons one at a time in this order R, Left, Down, Square, Triangle. The cheats can be disabled by clicking on cheats (I never got a chance to actually create the menu so when you activate it they are automatically enabled) The cheats that have been added are:
o Hyper Speed, lets you move a little faster than normal.
o Super Homing Missiles, makes your bullets home twice as
fast.
o Infinite Lives.
o Infinite Slow-Mo.
* Fixed homing missiles so they home on enemies more reasonably. (I never got a chance to perfect this but it is better than the last release.)
* I’m sure if there are more updates but as I stated earlier I cant look at it while writing this so I’m just going to leave it at this.

Here are the release notes:

I don’t really have any applications to test this with right now, but over the last few days I’ve totally rewritten the scripts that compile the Open2x libraries which resolves a few long standing problems (not the MOD with SDL_mixer problem nickspoon but I am looking into that – I have confirmed it is true 😉 ), updated most of the libraries to their latest versions and have added a few new ones. Anything included will most likely be included in the Open2x firmware for dynamic linking (to give an idea of how much we’re trying to cram in there).

All this stuff should find its way into SVN within the next day or two, so if you prefer to compile your own libraries, it won’t be long now 🙂 .

To use it, just extract into your toolchain directory (compiled for the gcc 4.1.1 Open2x applications toolchain, but it will probably work on DevkitGP2X and maybe our kernel toolchain). If anybody who tests this could post here with your experiences, it’d be much appreciated!
