Homebrew CitrAGB - 3DS GBA Emulator (WIP)

[pedro702]

nice i really need to get a N3ds to get decent homebrew it seems.

 

[Jacobeian]

SNES has a 16-bit 22 Mhz processor, and the GBA has a 32-bit 16 Mhz processor.

SNES CPU is running at max 3,58 MHz

New updates for CitrAGB!

• CIA releases are now N3DS-enhanced, giving the 3x speedboost seen in ninjhax2 in addition to the existing dynrec. Most if not all games run full speed now for N3DS.
• The home button is functional in all screens.
• X now goes to the home screen for CIA releases, allowing you to exit the app or switch apps in the middle of a game

Most notably, games which were OBJ-heavy have had their drawing times dramatically increased for N3DS CIAs (ie Spyro), vblank and hblank interrupts now do not cause lag at all (this was especially noticable in Pokemon games during grass battles). This basically brings it up to par with the speeds you'd expect from a PSP or similar device running a gpsp port.

As usual, the latest releases are in the main post.

EDIT: A note to those compiling from source, you'll need to compile the latest version of makerom from profi200's Project_CTR Github repo in order for the RSF to work with the added flags for N3DS enhancement. I don't have a setup to compile those for Windows or Mac at the moment, so if someone could compile that I'd appreciate it (and I'm sure other homebrew authors would as well).

How does the cia Ver with dynarec in O3DS?

How does the cia Ver with dynarec in O3DS?

Runs the same as N3DS used to run with dynrec but no additional speed boost. About the same as N3DS is on Ninjhax2, maybe better in some games and worse in others.

How can you traduce that on fps?

awesome, time to try space channel 5 \o/

Did a small comparison video in case anyone was curious about the speed gains from o3DS/n3DS dynrec to N3DS 3x dynrec, for some games it makes no difference, for others it removes all previous stutters. In any case it makes most games playable without stuttering in sound or fps:

My camera didn't do it any good for the screen unfortunately, but the sound gives a general idea.

Grabbed the latest .cia. DKC runs perfectly on the N3DS. SSF2TR on the other hand..........almost locked up the System if I did not Exit out of it. Everything just crashed down in terms of FPS. Dont know if a Unmodded Copy would do it. Mine has been Trainer Patched. Thing is, DKC is Patched in the same way and it works perfectly

Hm, not sure on that one. I'll have to test on that one, but I don't see any reasons for it to run super slow unless the game itself has some weird wait loops or isn't compatible with gpsp at all.

 

[Smoker1]

Will test on an unmodified Copy

Edit: Normal copy of same Region (E) works perfectly same with the (U) Version

Are you going to try to get this up to speed on Ninjhax 2.x like mGBA?

It's not even opening now on O3DS

 

[Deleted member 359106]

very nice speed on n3ds cia, is there a scaling option? And no fps cap or Fastforward button?

 

[Smoker1]

I 2nd that inquiry. Would be nice to increase the Screen Size to see how it works. If anything, the RetroArch gpSP Core is OK. But has slowdowns at times with certain Roms.

3dsx or .CIA? Does it just hang on launch or is it the emulator crashing on opening a ROM?
