DS development > [Fixored] GBFS -> Works in Dualis, but not on Hardware...

#76944 - JessTicular - Sun Mar 26, 2006 5:46 pm

Hey guy's and gals,

I've spent the better part of a day trying to get the GBFS to work, but finally got it running nice and smooth on the latest version of Dualis.

After a small dance and clap, I figured I'd give it a shot on hardware.
Unfortunatly... It doesn't work! :(


All I'm trying to do is print out how many files are stored in the system, which is pretty straight forward in the code as:
Code:
  GBFS_FILE const* gbfs_file = find_first_gbfs_file((void*)0x08000000);
  iprintf("\x1b[1;1HTotal GBFS Files: %i\n", (*gbfs_file).dir_nmemb);


Dualis reports the correct number (1), but the hardware reports a silly number of 58771.


The basic run down of what I'm doing is:

Create normal .ds.gba & .nds files,
create a gbfs file system,
pad out to 256,
append system to .ds.gba & .nds files


( I figured out what to do from Chris's tutorials ( double.co.nz/nintendo_ds ), the example with DevKit, and various Forum Posts + Readme files )


Here's my workspace for everyone to gawk at and possibly laugh at me (hey, I'm new to the DS, cut me a break :P);
http://jt0.org/dl/ds/gbfs.rar

To get it going, simply run the makeall.bat file ( Does a clean, builds the app, then appends the gbfs ).


Thanks for any and all help as to why it's being silly!


Cheers,
Jess.

What kind of hardware? The find_first_gbfs_file() function does not work with FlashMe+WMB or with GBAMP. In those environments, you'll have to create the GBFS file, bin2s it, add it to your project, and then use that instead of find_first_gbfs_file().

genfish,
Yeah, already checked that out during my countless forum searches; It helped, but since I'm running a normal makefile, THEN appending the data to both the .nds and .ds.gba files, it doesn't apply.
Thanks anyway, mate.

Tepples,
An EFAII (1Gb) - I have used FlashMe, so would reverting to the old firmware fix it?
At any rate, I assume bin2s makes a header file, giving me the pointer to the appended data, and from there, I can still use the functions for getting file objects? or is there another way to determine where files begin and end?

Cheers for the help guys,
Jess.

[EDIT]
As an aditional: Wouldn't using the bin2s mean that it is compiled as part of the source, and thus I cannot exceed the 4MB memory limit of the DS?
That could be a real bummer in time to come when I add sound + 3D models and textures.
Is there any other File System alternative ( or a personal implimentation of find_first_gbfs_file() ) That could be used?

FlashMe has nothing to do with it.

bin2s makes an assembly language file to be added to your project. A file named "data.gbfs" becomes an object called data_gbfs.

Correct. If your storage device cannot use ds.gba files, then it is limited to 4 MB unless file I/O is possible.

The Windows game ".kkrieger" is 96 KB.

There may be a library that you can use to read and write files on the MK2, MK3, NinjaDS, or similar SLOT-1 SD adapters. These libraries generally implement an interface similar to that of the standard C library's fopen() and friends.

Alrighty, sweet.

Thanks for the helpful info!

My cart runs .ds.gba fine, so I should be right with the size limit :)

And, .kkreiger? Haha, I wish I was good a procedural generation! Those guy's are working on Spore now - Talent that has anything but gone to waste :)

At any rate, thanks for the help, mate.

Jess.
