Homebrew Gba full Speed on O3DS?

[stl25]

One of the members found a way to create 500 kb forwarders that you can install to emunand and they work as if the GBA cias were on both sysNAND and emuNAND. I use this on my N3DS with A9LH (arm9loaherhax) with AuReiNand 3.5.3 booting by default to emuNAND. Works the same way on O3DS.

Sorry just realized he is on 10.5.0-30 FW. What about that hardmod procedure to downgrade to and exploitable firm like 10.3. You could go that route then do A9LH since you would have the hardmod.

GPSP's average frame rate in Fire Emblem is 16-18. mGBA's (non-retroarch, with BIOS) is 24. Are you sure you're using an O3DS?

I'm on n3ds, but i was talking about the retroarch version.

Downgrade to 9.2 and then use a CFW that modifies AGB_FIRM and lets you play GBA games without emulation.

Unfortunately, it is true that 10.5 requires a hardware mod to downgrade.

I've tried this, but it always gives me an error when trying to launch any games, and I can never get it to work.

Did you install the games to both sysnand and emunand and if you're using rxtools is patched agb_firm selected in settings? If so it should work

I will double check the agb firm in settings, but yes, I installed them both to sysnand and emunand. Not to mention, Should I have installed the agb_firm into sysnand, too? (I did)

EDIT: I went into rxtools settings, enabled it and it still is giving me an error. Should I use rxtools in sysnand or update rxtools?

The OP was specifically asking for help with an O3DS. GBA emulation behaves differently between the two, so disclaimers are important. Sorry.

Don't know what to tell you then, if you downgraded from >9.2 it might be a downgrade problem if not either somethings wrong with your system files or you're missing a step

I doubt it since everything else works fine. Should I update rxtools?, and if so, to what version?

I have a DSTwo Supercard in one of my O3DS and use the GBA emulator plugin, seems ok.

It could easily be one .cia didn't install correctly or something, the downgrade is REALLY finicky. I use the latest nightly although a lot of people use the latest 3.0 beta which I think is 6 or they use 2.6 which was the latest full release.

Is it possible to run gba game at full speed on a O3DS using homebrew (no cfw) on firmware version 10.5.0-30 U?

Like, everything in that question is a Noob / Kiddo indicator.

It seemed like everything installed correctly, though. The downgrader went through and performed everything successfully. Also, is there a way to check my version I have now for rxTools? Updating rxtools was getting finicky today so I will need to try again when I can.

With CFW, some GBA games run fullspeed under gpSP. Even then, most games you're stuck with Nintendo's crappy VC. Without kernel access, you're just out of luck on the o3DS.

My n3ds I downgraded said everything installed correctly but trust me it did not. If you care about having gba VC games I recommend reinstalling 9.2 by downgrading with the gateway exploit on o3ds or with the downgraded again as a .cia and then updating to 9.2 with sysupdater or with a game with the 9.2 update. As for checking rxtools version if it's not written on the menu I don't know but you should probably use a recent nightly

 

[Deleted User]

Unfortunately not. It's better to just play GBA on your phone. Even a DS plays GBA on the emulator better than mGBA on O3DS.

That's because of the hardware

Well at this point, Im really only using it for pokemon emerald, which runs full speed on gpsp with cfw, so if i find another game, I will look further into it.

would you kindly link me to that thread?

You don't need CFW to run GBA games full speed with gpsp. You do need an N3DS though.

 

[Clydefrosch]

even vc injected gba games arent that enjoyable. even though they run at full speed, for some weird reason, they also look really grainy and mushy for all kinds of games when the whole screen is moving

Yeah, Nintendo deliberately had it try to emulate the look of the old GBA screens. It gives me a headache, so I don't even bother with it. If someone ever finds a way to remove that nonsense from the AGB_FIRM, I'll probably try it out again.
