Homebrew Homebrew Development

Strange... what game is it? I can try it out myself and see what the problem might be.

I'm also getting this, both when I compile it myself and using your build. I think there might be a size limit which could be causing it to error though,so I'll fiddle with some smaller ROMs.

Just fixed it, redownload from the readme.

The issue was the check for game info in the large array in 3ds.cpp. The array size is 256, but it doesn't actually have 256 entries and wasn't checking for null, so a game that wasn't on the list would end up reaching the null entries during the check and would crash.

Oh, and for reference, the ROM I've been using to test is Pokemon Emerald. 16MB I think.

Where is the .3dsx file in the zip?
I use ninjhax.

Just recompiled, still nothing, even on a small 6.3KB homebrew I made. And it seems the ZIP only has a .elf and an sdmh in it.

Oh, whoops. Zipped the elf instead of the 3dsx. Fixed now. Although, it should work, strange that it wouldn't. Sonic Advance works now at least. Try testing it in 3dmoo and see if the console prints any errors containing something like "read32" or "write32".

Ported vba-next to run on the 3DS, currently it runs a bit slow and has no audio, hopefully that can be remedied sometime soon.

It's open source (3dsx download also in the readme): https://github.com/Steveice10/3DSGBA

thanks Steveice10
working fine.(slow y no sound like you said but working)
can you change the exit button from "x to start"?

The start button is used in GBA games, so I can't really use it for exit without making things awkward.

Works now, and quite well for a port. Odd that it didn't work when I compiled it though. What version of ctrulib/GCC are you using?

oooops, forgot about that.
anyway keep up the good work.

I think I'm somewhere around this commit: https://github.com/smealum/ctrulib/commit/58192c868318e2d7cb44dc6e185710a84ba57952
I should really get around to updating my ctrulib though.

button combo is probably better than a single button press.
Pressing X is too easy, that would exit the game without warning (unless you added one).

Start+Select is already harder to press by mistake.

I'm currently almost finished with a file selector. When in a game, touch will pause the game and open it, and when in the file browser a touch will close it and resume the game and start will close the emulator.

Aaand its in! No more boot.gba!

I'd personally just allow the binding of a button to open a menu, or just use the touch screen as a button like gameYob and blargSnes.

Hi! I've just released a 3DS build of Headcannon Game Engine. I wanted to make mention here, but since I don't want to SPAM this thread, you can find out more in this thread

Also, though, I'll share this:

I've added buffered read/writes to SDMC in my own personal build of ctrulib to greatly speed up multiple sequential, short reads/writes. You can get the modified SDMC source file here. I'm not sure if it's the best method, but it works, and if anyone responsible actually wants to add it to the official ctrulib, feel free. I would appreciate credit for any usage, though

Incidentally, I had added chdir too, but that was officially added to ctrulib before I was ready for posting, so I've merged the official method into my source. As far as the public official source goes, this should be up-to-date

You should submit a pull request to the ctrulib repo! The learning curve for git is a bit steep but it's well worth it.

Done; thanks for the suggestion!

I think that the 3ds homebrew community here on gbatemp should set a standard that a certain keypress would be used to exit homebrew. Personally, I would use L+R+START+SELECT.

yup, would be nice to have some consistency. Start is obviously not a good idea (especially with emulators), as many already associate it with "pause".

I personally prefer the touch screen exit implementation. Works a bit better imo and you don't get confused as much.

Tbh, I'm down with anything as long as it is mostly consistent between apps, and wont be confused with something else later down the line. I haven't started creating yet. I expect to start working on learning the basics of creating things in a couple weeks, after exams are done.

On that note, if anyone is willing to point me in the direction of where to start (like the very beginning lol. I have a weak understanding, other than a bit of CSS, right now), I'd be eternally grateful.
