Homebrew StellaDS V1.2 (DSi Entry)

[alekmaul]

Hi All,
Here is an Atari VCS 2600 emulator for DS and DSi (compiled with last libnds and devkitpro), a port from Stella Emulator.
To use this emulator, you must use compatibles rom with a26/bin format.
Do not ask me about such files, I don't have them. A search with Google will certainly help you.

Controls :
* Direction pad : the joystick ...
* A : Fire button
* X : Left Difficulty A/B
* Y : Color / Black&White Switch
* R : RESET (yes R like Reset

)
* L : Change controller (paddle / joystick)
* SELECT : SELECT Trigger
* START : Show FPS

Of course, i'm releasing the source code because I am not the original author of Stella Emulator : StellaDS source code

V1.2 : 06/06/2011
* Change screen height when switching from PAL NTSC
* Add fps display with START button
* Add stylus management for paddle

Nice! Glad to find it works with Sudokuhax, as I share an SD card between my hacked wii and DSi and therefore already had the complete 2600 set installed.

Great! So many great things have come out of this homebrew competition. GBA and 2600 emus, remakes of games, many homebrew games, etc. At first I didn't see the point in this homebrew competition, but now its just so obvious! Hope to see a similar contest next year, and good luck with this emulator.

MY.GOD.YES.

I have to wonder if alekmaul read this at all?

OK, I take back part of my last post - perhaps handy isn't the easiest to port.

What we need is a better port of STELLA.

The file selection is so damn broken in StellaDS that you often load the rom below or above the one selected, and the load times....load an atari game in stellaDS and laugh your ass off as you watch how long it takes to load a file that's a few KBs big.

Hey Alek ! Nice to see you entered the bounty.

Good luck !

 

[wasim]

nice work

And good luck

Many, Many, Many thanks for this one. This should bring back many memories from when I was a kid.

 

[Schlupi]

Yes! Awesome!

Why oh why won't others update their emulators?

 

[ferret7463]

good work

I love the interface on the bottom screen. A quick suggestion, can you clear up the sound some. It crackles a lot, not that i am complaining . You have done a way better job than i would've. Thank you for the EMU.

alekmaul I hope you don't mind, but I have added rom loading via launch arguments so that other menus can be used for loading roms.

The updated source + binary can be found HERE.

The only change I made was to add:
CODE
//load rom file via args if a rom path is supplied
if(argc > 1)
{
dsShowScreenMain();
dsLoadGame(argv[1]);
etatEmu = STELLADS_PLAYINIT;
}


to main.cpp before dsMainLoop();

Alek, what is the maximum amount of .a26 files we can copy in one directory ?

 

[Recorderdude]

does it take both .a26 and .bin? I've got two atari sets but it would take ages to get to the game I want via the huge a26 one.

In the readme.txt we can read :

QUOTEStellaDS is an Atari 2600 console emulator.
To use this emulator, you must use compatibles rom with a26/bin format.

 

[Recorderdude]

OK, cool. Will try this out.

 

[NamoNakamura]

Tons of love! The previous version actually ran certain games slowly!

 

[Another World]

anyone try the Starpath Supercharger games to see if they work?

i haven't had time to grab mine from storage.

if you guys just want to test this emu out legally don't forget that there is atari 2600 homebrew.

this is an awesome first release, i can't wait to see what comes next. alek always keeps his projects updated!

cheers!!

=====================
quick edit here.

when i'm in root of my msd card the top of the emu says #/# games. it would be nice if it checked the directory for .a26/.bin files and if none are found that it instead said #/# directories.

i clicked power on/off and selected no. when the main screen came back i now have two power buttons. the second one is just a graphic and i can not select it. it appeard to the right of the first one and covers part of the words for "tv type".

for the next version please consider adding dpad/button combination menu options.

i tested a few starpath starcharger games and they just freeze up the emu. when the emu freezes either its with a sound constantly playing or the top screen just freezes, also on the bottom is this weird graphic that appears under the "me" in "game". when its frozen i can still softreset in AKAIO so i'm assuming its not the emu thats frozen just the emulation of the rom has errored.

i have some starpath homebrew that i've upload, the link is below, please test.

^^ tetris works but the screen shakes around. i don't have time right now to test everything i have for the starcharger.

Alek, what is the maximum amount of .a26 files we can copy in one directory ?
Tested myself and don't put more than 255 files in a folder or the emulator will slow down a lot the file list process.
@alek : The color/B-W switch is supposed to work in this version ? Also the game select and game reset button switch do not work.
QUOTE(Another World @ May 20 2011, 11:26 PM) anyone try the Starpath Supercharger games to see if they work?

Tested a couple of them without luck.
BTW, the emulator run fine in dsi mode on my ievo.

 

[Buleste]

Are there any plans for paddle emulation?

 

[VatoLoco]

This is a nice update, thanks Alek=D
Atari2600 was the first system I owned as a kid, so playing these games is always nostalgic fun for me.

Also, thanks BassAce for adding the argv to it. Looks like I need to find a set of Atari boxart for the direct game launching from BAGplug =)

 

[alekmaul]

thanks for all your tests, i will consider your remarks for the next version.
Currently :

- pb with starpath supercharger (will check v2 release of stella)
- paddle emulation (why not, good idea with the stylus)
- pb with root directory and strange #/# display (don't really understand the pb but will check)
- dpad/button combination menu options (what do you want exactly, adding conf for but #1/#2 and triggers to remap them to DS buttons ?)
- power on/off and selected no, pb with graphics
- adding load argument with BassAceGold tip (which menu uses it, your menu ?)

About B/W switch, it doesn't work for all games because i think it must be supported by the game. It's not a palette modification but a hardware switch in the A2600 machine.
Also, the maximu number of roms is 1024 per directory, I think it's enough ;-)
At least, it's not a fork of previous version from thechuckster, as you can see in source code, this version is rewrote from scratch for the DS part.
