Gameboy Advance News
Motocross Challenge and Thrust Advance released on Cartridge (GBA misc)

Here are news from Heavy Stylus!

With Grumpy Cat & DHG’s help and authorisation, RGCD have produced a limited quantity of Thrust Advance and Motocross Challenge cartridges and are selling them at cost price via our shop (http://www.rgcd.co.uk/shop). Info cut and pasted from website follows:

“RGCD have teamed up with some of the best homebrew developers to bring you the RGCD cart project – top GBA homebrew games on cartridge, sold at cost price and in very limited quantities. Our first cart release was Grumpy Cat’s awesome ‘Thrust Advance’, a tribute to the Firebird classic of old and quite probably one of the best examples of quality retro gaming available for Nintendo’s single-screen handheld.

Following that, our second release is a game that a lot of you have been waiting for… RGCD and DHG Games present the authorised cartridge release of RGCD #02’s featured game; Motocross Challenge!

Originally planned as a commercial GBA release, Motocross Challenge had been in development for three years by relatively small indie developer DHG. In 2006 they signed the game to what they describe on their website as “a very big and international publisher that shall remain unnamed”. After a further six months of solid work, the game was finally completed in February 2007 – yet while it was in final testing the publisher decided that the GBA market wouldn’t support enough sales of a non-licensed game to make releasing it worthwhile. The project was thereafter cancelled, despite just needing to be written to a cartridge, stuck in a box and shipped to the shops.

Without the necessary resources to port the game to another platform and with a strong desire to actually let someone play the damn thing, DHG made the amicable decision to host their opus for download from their website. However, following our glowing review of the game, we at RGCD thought that this outstanding title should be given the proper cartridge release that it deserves. So with DHG Games’ authorisation we’ve created a limited batch of MXC cartridges for you to buy and plug into your GBA, SP, Micro or DS!

For the small sum of £8.50 (including P&P), MXC can be yours to own today. As per RGCD’s other cart releases, MXC is strictly limited to less than 100 carts.

(Please note that MXC now has a (limited) save function; the game saves your last achieved password in the cart’s SRAM, saving you the bother of having to write down codes after each game. Bonus! Also, there is a reason this cart is for sale for considerable more than the usual price – DHG requested that we send them 20 carts in order for us to proceed with this cartridge project, and clearly the money to buy those had to come from somewhere… However, when you take into consideration that this was originally coded as a commercial game, our budget price tag is still very reasonable.)”

We’re looking to release several more homebrew carts, so if you’ve got a game that you’d like to see released, drop us a line via the website.

The shop is STRICTLY NON COMMERCIAL!

gbaMouse (GBA misc)

Author release notes:

I’ve spend some time the last couple of days trying to devise a way to get a sort of mouse working on the gba using the gbaccelerometer. Here is what i have come up with so far. I created some sort of library called gbamouse.
It reads the values from the gbaccelerometer and provides these as acceleration on the axis, rotation around the axis, angle between rotated xy,yz,zy planes and the corresponding untransformed planes.
Unlike a sort of joystick, a tilting of the gba from the original position doesn’t represent movement of the mouse, but an absolution position that is relative to the original position (i.e. calibration)

I provided a little example to show the settings. One can browse through them with the dpad. It also shows the values the mouse object reads. One can turn that off to see the mouse running at ‘normal’ speed. So far everything is programmed using floats (and pretty fugly), because this is a proof of concept.

I hope that people test this and give feedback, and their favorite settings.
I hope that eventually people will port some old dos game or so (that is if they havent all moved to the DS yet).

Anton

(ps:)The settings are:
source of mouse x and y values – either axis angle, plane angle or values directly from accelerometer
x/y sensitivity – the higher the value, the farther the mouse will go on tilt
x/y mouse lag – its a sort of filter to avoid small jumps; it represents how much the difference between old mouse position and new measured mouse position is to be multiplied by to get the new actual mouse position
one can associate a button (or more) with the mouse, for movement and calibration (in the example i used both shoulders and select)
calibration – calibration on pressing mouse, releasing mouse, no calibration
center on calibration – either center the mouse on calibration, or keep it where it is
when to move – move or not on button press, move or not on not button press

PocketNES (16-07-2007) (NES emu for GBA)

PocketNES is a Nintendo Entertainment System emulator for the Gameboy Advance.

Changes:

* Palette updater fixed, no longer writes out of bounds
* Duck Tales Fix (supports changing 8×8 sprite origin between left and right pattern table per scanline)
* ‘dirty tiles’ system for CHR-RAM games
* Different code for updating the sprites
* These two together fix sprite glitches in Battletoads, Wizards and Warriors 3, and more.
* Also a buggy and broken dirty tile system for CHR-ROM games
* New per-scanline scrolling code fixes Slalom, horribly breaks Rad Racer
* sprite visibility per-scanline buffer updated in sync with rest of buffers
* Fixed a little bug which caused harmless extraneous memory writes
* Yes it’s really buggy. Has a new ‘new frame’ system which fails in lots of games.

Powder (24-06-2007) (GBA Game)

POWDER is a roguelike developed specifically for the Gameboy Advance (GBA). It is not a port of an existing roguelike as the controls of the GBA are very different from the traditional keyboard, and the screen imposes some additional limitations. It is built around replayability and long term ergonomics, not short term learning. It uses actual graphic tiles (16×16) rather than the traditional characters.
