Homebrew gbaemu4ds: GBA emulator for DS(i) (DSi Entry)

[ichichfly]

Interesting. When I read the OP i thought someone was bullshitting and that this was just a joke some people were going along with.
I'd love to test this (though i don't have any GBA homebrew to test with will have to try and find some) but remember compiler hell when I once tried getting them setup so will have to wait for a possible browser version.

Edit: Argh, now I remember why I hate compilers I can never get them to work. I open the makefile and tell it to "make" in programmer's notepad. It says ""make": *** No targets specified and no makefile found. Stop."

are there any blank inside the path?

devkit don't support blanks inside the path

It uses NitroFS? Didn't realise that. I didn't put a ROM in the folder, could that be the reason for my errors?

what error do you get exactly

to fix the color problem, the following values should be changed in the main.cpp -

systemRedShift = 0;
systemGreenShift = 6;
systemBlueShift = 11;

Should be

systemRedShift = 0;
systemGreenShift = 5;
systemBlueShift = 10;

thanks

Wait does it like work on a flashcart?

sorry i was wrong it don't work on some cards it seems it work on some. It won't work on my old (broken one)

just used this to play pokemon on the orginal ds and it works but sometimes it dose freeze for half a sec every 20sec or so

was that a COMMERCIAL pokemon game? and what was the rom size?

The creator claimed it only played homebrew under 2mb.

Pokemon Emerald Version

Buttt...the limit for now is 2MB, is it not?

this can be but it will crash after it try to load data from uppern the 2MB and it can't save so i just write no commercial

Are you able to add in support for DSi's extra 12MB RAM for loading larger files in the future?

This is getting veeerrrryy interesting! Go DSi homebrew!

Um why don't you upload the file in Filetrip(official gbatemp download center)

Because no build has been released yet?

For those people, that get compiling errors: Just install latest devkitARM with devkitPro updater (including all sub folders) and it should compile fine though it takes quite some time.

At the current state, this is basicly a *.gba to *.nds converter. With this you can make *.gba files to *.nds files and play them with your flash kits.

The title is confusing me, it's only for DSi or it works also for DS as long as the file is small enough?

That's really awesome and unexpected, but prepare yourself to receive tons and tons of people whining "why X don't work, why Y is slow, HELP PLS".

@ichichfly
Good job on the POC

DSi only. Takes advantage of DSi mode so yeah...

No it's not. It works on DS and DSi.

really? Oh well even better

 

[indask8]

It works on DS? sweet, I'm going to try tonight (I'll receive an Ievo wednesday or thursday).

 

[WiiUBricker]

Since it works on DS and DSi, perhaps a mod should edit the topic to "GBA emulator for DS and DSi"?

edit: if you guys need proof, u can try my compiled build yourself, but the speed is shitty ( I guess 1-2 FPS).

 

[Vigilante]

So what homebrew does it best emulate?Links please.

It doesn't 'best' emulate anything, everything is the same... Really, really really s-l-o-w with about 1fps and no sound. You really should not expect anything more.

Anyone not happy with the display, should make the following change in the gba.cpp

replace the systemDrawScreen() function with the following, it might (not 100% sure) help a tiny tiny amount with the render speed also -

CODEvoid systemDrawScreen()
{

ÂÂÂÂu16 *pointertobild = (u16 *)(pix);
ÂÂÂÂfor(int iy = 0; iy 5) > 10)

new rev http://www.mediafire.com/file/zsbxr94eu20krds/gbandsr3.zip

there are 2 nds inside as well as 2 src arm9 is just the old code with spinal_cord patch (thanks)

the other hwspeedup use hw to speed the code 15% up but it seems it only work in well in BG mode 0 most games use other these just have Graphic bugs (you can't see anything)

i hope that i can fix the bugs in the other BG mods and in the next rev i will try to use dmaCopy more often

this is an update because someone asked me in an chat

ADD:About the speed of hwspeedup on DS emulator it has 10% speed of the original but frames are only displayed every secound no mather what speed the game realy have you can change that lower by editing the src but my if you put it on 6 per secound you get ~10% less speed --> 9% of the original

Thank you for the compiled version. I have tried it, and I am very, very impressed on this feat. I'm going to try NegativeSpace and see how that works. Would you mind if I link to the download on other sites (Obv. on the latest version) and advertise it? I think more people should know of this.

It work on DS and DSi but it runs faster on DSi in DSi mode

Sure. I was going to be sure to say that because I can't load any retail games, as of the filesize limit, and whatnot. Could I mention it is in "beta" and link to http://www.mediafire.com/file/zsbxr94eu20krds/gbandsr3.zip (Or the latest link)?

Looked into the source, and it looks like you're basing if off VBA, if I'm correct?

And this is absolutely amazing, by the way. If this gets enough progress and possibly wins the bounty, would you consider a DSTWO version? The bounty reward DOES give you enough to buy one

Why do i get an error opening image gba.gba?

Did you DLDI Patch the emulator?
