gameplaySP (gpSP for short) is a GBA emulator written completely from scratch. It is still pretty young (only having started a 3 months ago)
and thus rather immature, but it does a decent job of playing a number of games. It is currently very minimalistic, in the sourcecode, presentation, and features. Its number one focus is to deliver a GBA
gaming experience in the most playable way that PSP can manage, with frills being secondary.

Having said that, optimization was the important way in achieving this goal, with overall compatability being a near second. Because of this
some games may not run at the favor of running more games significantly better. Of course, the compatability will improve with time.

Many games will run at their best out of the box, but some games will run very slowly unless idle loops are taken care of. There is a supplied
ROM database, game_config.txt, that gives idle loop targets and other settings that may help a game to run better (or at all) on a per-game basis. Currently (as of the first release) only a very small number of
games are entered. This number should improve dramatically over time.

gpSP currently requires an authentic GBA BIOS image file to run. It will make no effort to run without one present; this file is 16kb and should
be called gba_bios.bin and present in the same location as the EBOOT.PBP file. Please do not ask me where to obtain this, you'll have to look
online or grab it from a GBA. Note that it is not legal to have this file unless you own a GBA, and even then it's rather gray area.

-- Features --

gpSP mostly emulates the core Gameboy Advance system. As of right now it does not emulate any special hardware present on various GBA cartridges.

What it emulates:

GBA CPU: All ARM7TDMI ARM and Thumb mode opcodes except block memory w/ s-bit (probably aren't used in GBA games) Video: Modes 0, 1, 2 almost completely, basic 3-5 support, sprites,
windows/OBJ windows Interrupts: HBlank, VBlank, all timers, all DMA channels, keypad DMA: Immediate, HBlank, VBlank, sound timer triggered
Sound: Both DirectSound channels and all 4 GBC audio channels Input: Basic GBA input delivered through PSP controls Cartridges: Currently supports up to 16MB large ROMs (32MB will not load)
Backup: 32/64kb SRAM, 64kb flash, 512bit/8kb EEPROM

What it lacks:

Video: No mosaic, bitmap modes lack color effects (alpha, fades), there might be some minor inaccuracies in blending...Cycle accuracy: Very cycle innacurate; CPU is effectively very overclocked, meaning games with rampant idle loops will probably run very poorly. DMA transfers effectively happen for free (0 cycle). Please do NOT use gpSP as a first source for developing GBA homebrew,
try No$GBA instead.Backup: 128kb flash is not currently supported.

-- Controls --

The control scheme is very simple and currently can not be changed.

At the ROM selection screen:

Up/down: navigate current selection window.
Left/right: switch between file window and directory window. Circle/start: select current entry.
Square: go one directory up.

Hi, this is my first game for DS.
Sorry if it will doesn't work correctly on DS (it run fine on dualis) but i don't have the hardware to run homebrews because i only have the DS

Hello, here is my entry for compo. It's called DDRLite, which stands for Dance Dance Revolution for the Nintendo DS Lite.

DDRLite comes with 3 songs (which are copyright by there respect authors/owners) and the ability to convert your own DDR songs, only .sm (Stepmania) format is supported in this version.

To use the menus you use up/down to go up/down, and start to select. On the first menu you'll need to choose the touch mode, my preference is Linear. On the second menu you'll choose your difficulty. Not all songs support all difficulies, and if they don't it will show no arrows. The third and fourth menus are navigating to the desired song.

When in game use the a/b/x/y/up/down/left/right buttons to hit the corresponding arrow when it reaches the gray arrow at the top. If your using the linear touch mode, the bottom screen will be used and you will hit the gray arrows as the green ones reach them. If you using the Dance Mat mode you'll do the same, except hit the arrows that are in a diamond shape.

To convert your own songs open a command line window and run the "DDRLite Converter.exe" application followed by the "input" dir and then the "output" dir (remeber quotes). Please remeber when putting in your own songs to put them in __Letter__:\DDRLite\Songs\__GROUP__\__SONG__\ .

__Letter__ being the letter of your flash media, __GROUP__ being a folder containing a number of song folders, and __SONG__ being the actual song folder.

This is a puzzle game. The game can have up to 112 stones on the play table, where each stone must have a pair, so there are 66 possible matches that can be made.
The goal is to remove each stone from the game table, u must first select 1 stone and then another one of the same kind. The catch behind this puzzle is that when u have clicked on 2 of the same stones, that in the background there are going to be drawn Lines (Up, down, left, and right) from the first selected stone. But this Line can only make MAX 2 corners! So u must visuallize those first and then click on the stones.

Time for another update:

This is going to be my final update. As i dont have time to comtinue it tommorow....

A well here is a list of the new update:
- Fixed several bugs
- Timer should work ok now
- Redone some main graphics
- Added the remaining sub-menu's ingame
(Should be more, but i cant come up with them right now. I am very sleepy right now ....)

As i said i would add a highscore list, wel it is sort of there but it is disabled. As i was saving the data, he didn't saved it right. But im to sleepy to look further into this one, so it is a shame i cant have it in at the end of the compo .

As wel as the other remaining (todo) stages and level, wel it requires a time to think about the levels because they should get harder when u get further into the game. So for this i just have to little time left.

Ok thats it for me. Hope u all enjoy playing as i am . And i hope u get past level 9, thats a hard one lol. (I tested all the levels, and they all can be done).

Night boys and girls... Im going to bed !

Today I'm pleased to announce a new version of cwcheat: 0.1.2.
This version has various improvement including:

-cheat searching directly from the psp with 8/16/32BIT support, continue support and reporting of the values of the first ten adresses. Directly from the cheat search menu is possible to add to the codes what you have just found to try it (it doens't add it to the on memory stick database at the moment)

-improvement on the 32bit multi adress write code which permits now to use not power of 4 adresses (before this resulted in a crash)

-fixed the usb mass support: now it's auto enabled correctly when the prx is loaded if you selected it in the options

-now codes are applied without waiting 1-10secs anymore so for example the life bars are now froze

NB: I couldn't update the manuals because i don't have adobe acrobat with me right now

NB2:The change code value function is accesible from the cheat selection menu by pressing SQUARE when the desidered cheat is selected

This is like an advanced version of the Flash Monster game we posted the last few blog posts ago (and made by the same devs). They really know how to design flash well for the PSP, and I highly recommend checking out their site, http://www.maverickforce.com .

- Requires an internet connection.
- Edit Argon.xml to define folders to be parsed - and (you can add several entries), and the path to uLaunchELF.
- Weather (using the service provided by The Weather Channel) - working. Edit Argon.xml to set you location (here is an explanation on how to obtain your location ID: http://www.xml.com/pub/a/2004/09/29/weather.html). Pressing X on the weather screen will display a satellite image.
- Radio – categories list implemented.
- Photo - working, but libjpeg is damn slow. Thumbnails are shown for only the first five JPEGs (to speedup loading). Left/right - previous/next.
- Music – thumbnails implemented (folder.jpg or AlbumArtSmall.jpg).
- Still single threaded - takes ages to load...


Developers

If you want to help the project, here are the main tasks:
- SMS playback functions, if you are able to understand EEUG's code, I'm not, so I'm waiting for him to give me some clues,
- threads, semaphores, timers and stuff like that,
- high quality mp3 decoder (libmad maybe? - haven't tested it yet) - while SMS mp3 decoder is ok for movies (speed is more important there), for plain mp3's we can use something better,
- Shoutcast support,
- SMB support - http://ntba2.de/?p=libsmb, if it's performance will be adequate,
- DAAP support (iTunes sharing),
- AAC decoder - FAAC?
- visualization - based on something like that http://imagesavant.com/ or http://flam3.com/ (this one is opensource) or something else, but it should be extremely minimalistic (and I don't care about it reacting to the music),
- zlib support for those bitmaps and fonts,
- better icons.
These are more or less in the order of their priority. Contact me if you are interested.
