Homebrew CitrAGB - 3DS GBA Emulator (WIP)

[Psi-hate]

Smea mentioned that it got a speedboost in Ninjhax 2.0, but other than that I haven't heard anything.

I think @shinyquagsire23 is working on SALT still, or just at the moment reverse engineering more. Probably he'd be able to make a lot more of Citragb once he gets all he can out of his research.

Yeah I just haven't really gotten around to getting .cia working at all. Still being funky in regards to displaying stuff and whatnot, might have changed while I wasn't looking but I haven't tested it.

However in leu of ninjhax 2.0 being released soon, I figured I'd best fix up CitrAGB before I get flooded with questions on Twitter/here. First things first, you can finally load ROMs from folders. Frankly that was way overdue. Navigation through folders works properly as well, and you can also exit the menu without loading a game by pressing 'X'. While prepping for .cia support I also got us a snazzy new icon as well:

Spoiler

In addition to those fixes, I also did some prepping for ninjhax 2.0 coming soon. For now, due to ninjhax's lack of hb service and a lack of detection for ninjhax (for now), .cia building is there, but will default to interpreter mode unless modified manually to use SVC 0x7B. If you are on 9.2 or below and running the .cia, it will try to do libkhax, also not sure how well that will turn out. Frankly I haven't been able to get it to show a menu anyways so if someone somehow manages to get that working I might fix that. Aside from .cia support, since ninjhax 2.0 will work perfectly fine on existing 9.2 and below devices, CitrAGB will check the kernel version and if it is able to do memchunkhax on it, kernel dynrec support will be used. Otherwise on newer devices, it will fall back to interpreter mode due to the lack of HB_ReprotectMemory in 2.0 anyhow.

TLDR;

• You can load ROMs from folders now
• Snazzy new icon
• .cia support is still borked
• CitrAGB will support ninjhax 2.0, 9.2 and below gets faster kernel emulation and 9.3 and above uses interpreter

Well hopefully there can be a .3ds Version at least. For some of us, Ninjhax is kind of a pain to attempt to load/run especially on the N3DS

That probably won't ever happen. That would only benefit Gateway users, which probably isn't in Shineys interest, when Gateway users can also use cia's and Ninjhax.

I couldn't care less how it's ran since it's just homebrew anyways. The main issue is that it simply just refuses to work as a .cia (that and I don't think I've gotten any extra svc's to work yet either). It's kinda sucky though because testing .cia support burns me out really quickly going between installing and testing and copying over the .cia.

Well, with Ninjhax covering up to 9.8 soon, I imagine Gateway users can just run your emulator through a cN rom. Sooo, a .cia isn't too important right now.
That being said, maybe someone could come and help...?

A CFW USER Will never get whole world with CN rom，wether GW or cakesfw，rxtools.
Whether below 9.2 or on 9.8,they can't use libkhax，which means no dynamic recompilation.
Just interpreter.

 

[Kikirini]

Oh well? Until the cia happens, people will have to use what's available.

Actually rxTools devmode on sysnand allows for libkhax and other kernel exploits normally blocked by CFW that uses firmlaunchhax to firmalaunch newer native firm. So your statement isn't entirely true.

(on 3.x version of rxTools, DevMode is found in the advanced menu)

I know this works because I was able to launch Decrypt9 from Ninjhax (from a CIA of Cubic Ninja no less) while in "devMode" from rxTools.

Well,I finally get what devmode can do,Dynrec works on my 9.2 sysnand now

 

[XDM]

do we have any word on AGB_FIRM for Needs Gateway mode support?

So this is what devMode is for, so it means it can ve used to update using sysUpdater without any risk of brick (RXmode Sysnand blocks NATIVE_FIRM, so I suppose devMode isn't)

.3ds format should really be forgotten when it comes to homebrews, this crap is useless and doesn't even support sound properly, .cia and .3dsx should be the only focus, if only there was a .cia version of the hmebrew launcher, that would solve so many problems and we could have only .3dsx homebrews

Yes, it should be safe to use sysupdater in DevMode since it doesn't change the version of native_firm being used which was known for causing it to not update native_firm correctly.

.3ds does support sound if you set up the RSF properly. It just takes an extra step.

 

[mrolive]

Any updates on this?

 

[laharl22]

cia please

 

[Psi-hate]

All will come when it's done. He's stated several times that he's been busy with other stuff, and the Cia is still a work in progress.

 

[shinyquagsire23]

Just an FYI, libkhax fails to work from ninjhax 2.0, so devices on 9.2 and below cannot currently use dynrec properly (and the app will crash and burn). Not sure what the cause is, but I'm fairly certain it's outside the scope of CitrAGB.

So what's the solution, if there is any?
