Homebrew 3DNES - NES Emulator

[Arisotura]

Are you going to use the legendary GPU of the 3DS that everyone else keeps saying it's impossible to implement for homebrew (due to the lack of documentation)?

I wouldn't say 'impossible' personally, considering blargSnes does GPU-accelerated color math and brightness via creative use of multitexturing.

Rather, I'd just say that the PICA200 should be named Picky200. Do something wrong and it freezes. Occasionally also freezing the GSP service.

One thing you must remember is to always issue an odd number of draw calls. If you draw an even number of arrays, the GPU freezes. It's probably us doing something wrong, but perhaps some obscure bug in the PICA200, we don't know.

If in doubt, ask Smealum, he can probably help you in your quest to the PICA200.

No, sorry no answer before, i am very busy with university, it is the last month of class, then the *exam storm* started.

Anyway, i decided yesterday which i will rewrite the complete emulator, remove all warning, garbage, write a APU, write a new PPU with improves and write new CPU and the other mappers in pure ARM-Assembly, i will REing the Mega Drive emulator of Sonic(eShop game), to look some GPU functions i hope it may help with *full speed*.
Sorry my away, i hope do it before christmas.

I just tried to run some known Rockman rom hacks like rockman4minus infinity etc, they all loaded properly (worked slow or otherwise blurry with increased frameskip) except 4mi which just made my 3ds stuck after selecting a boss stage, all those roms i tried were rockman2 roms patched with IPS files.

Hopefully they will run smoothly on your next revision

 

[Jasper Peters]

Does this emulator work with Smea's Homebrew Launcher? If it doesn't are there any plans to make it compatible???

Oh, can you send me the mappers used by this hack rom and the hack roms too(PM Please).

Yes, it will work.

Good News

this is working on new ctrulib, this was amazing, but there is some issues(very slow), i am checking it, when i finish it i will try use 15bpp instead of 24bpp it would give speed improves(i hope), anyway it should work on SSSPWN now.

 

[Seraphiel]

Sounds awesome!, Good news for everyone indeed

 

[kane159]

i had tried some unlicence game made form chine(most of theme are mapper 199 i think) is it possible to support?
BTY i'm interesting in building a app for 3DS what can i learn first?i'm using windows and mac os 10.10 can u give me some suggestion? many thanks

I can't seem to get your emulator to show up in the homebrew menu for Smea's loady thing. Is there something I'm doing wrong? Then again I didn't see a .3dsx, just .3ds

 

[Keylogger]

Maybe renaming the .3ds in .3dsx will work?

 

[reprep]

so, how to make this work on ninjhax? The version on the first page is 3 months old and is an .3ds file, not .3dsx.

EDIT: In short, does anyone have the 2.0 version compiled as .3dsx?

For the moment, only blagrsnes and gameyob are working.

It will not work if it is a .3DS file

version 2.0 should work on ninjhax (old SSSPWN) but compiled .3dsx hasn't been posted if i am not wrong.
