Yes, you can. I use point filtering instead.

Well as of now i'll stick with VBAGX, since it's more Maintained and Developed as of Now.

Fair enough, as there are plenty of GB/C emulators that run full speed on the Wii, the GBA aspect is what's sorely needed and so far, I am very impressed. I assume though, the crackling audio will be fixed/adjusted in the near future? I mean speed-wise, this app is fantastic

Oh no!! random was Banned....That's way too sad.

What are you even talking about? mGBA is much better in everything GBA related bar the filebrowser. Performance wise it blows VBAGX away.
Did you try latest version?

...Yeah, mGBA has become so good that VBAGX just can't compete. Not even close.

@zerofalcon thank you thank you thank you thank you!!!!
Just tested it and it runs great, ultra fast file browser, custom ratio and directories, wiimote buttons control, overlays and even .zip support

Oh, here i get 32ΜΒ GBA roms giving me a codedump (1.0.2 build). Does the 1.3.0. build load them?
Maybe i am doing something wrong on my part?

Which 32 mb roms did you tested? afaik 32 mb roms cant be loaded for the mgba core. By removing and adding some lines of code helps to make those 32 mb load somehow, but it is very unstable with lots of dsi code dumps.

Sorry to get your hopes up guys, i got confused with Fire Emblem size, which is 16MB only. 32MB games will not work.It does run great though.

Any of you care to share overlays / resolution / proper settings to get this running pixel perfect?

Ok no worries.

As for the config, i use custom RA 1.0.2. and my mGBA core settings are video: custom ratio of 480X320 and resolution of 640X480. Also, filter is set to point filtering (no bilinear smear). Since it draws only inside the custom ratio it essentially gives a "double strike" image and looks amazing.
As for overlays, i use one of those that i attach in this post.

I'll edit first post with links to the most recent nightlies. VBGAX was good, but right now mGBA is the most accurate and compatible gba emulator.

--------------------- MERGED ---------------------------

How did you achieve that? I added -DDISABLE_THREADING to makefile, but no luck, which lines do you modify?

Sorry for the late answer, it is necessary to change some lines in libretro.c

What I did was to change/edit:

"rom = VFileFromMemory(data, game->size);" to
"rom = VFileFromMemory((void*) data, game->size);

And remove this line:

data = malloc(game->size);

After compiled some small roms tend to crash, especially 8mb roms and below. Dsi code dumps are generated too in random circunstances.

Hope it helps!

 

[nakata6790]

Hm, sorry for asking you again man, but can you make a mGBA core for 1.0.2 with those changes?
We can use the one you already provided for the 4-16MB GBA roms and the new one for the 32MB ones.

Nice, thanks for those, I like the scanlines one.

Btw, does someone know about the refresh rate? on this video is mentioned that the TV's does more than the GBA screen, so I was wondering if changing RetroArch refresh rate would make any diference.

I did some test and took some pictures if anyone want to see, I tried 608x240p and it looks pretty good, it tends to get more bright so I turned off contrast a little on the TV. The pictures (they are not great, but it shows the difference) were taken on a CRT TV via composite cables, all of the filters were turned off on both resolutions.

I don't know if the resolution I use is correct but I think it is, the custom I use for 240p is 480x160, for 480 the custom is 480x320. All of what I know was from reading from this thread on libretro forums.

Nice pics!

BTW the standalone mGBA recent updates fix a couple of games hat were broken before: MK Deadly Alliance and Konami Krazy Racers. Also, speed is even better now.
Can a more recent mGBA RA core be based on this newer build?

From an emulation standoint, that's really good to know. From a gameplay standpoint, Mortal Kombat games on GBA suck so hard is not even funny

Where can I find the newer RA 1.3? The last nightly of mGBA seems to output a better resolution, and you can load BIOS!

Latest Retroarch 1.3 official nightly for Wii, it seems they now added the mgba core up to date.

mGBA is awesome D:

BTW I want to cut some fat, what core is recomended for NES, and SNES respectively?

Nestopia & SNES9X Next

 

[ngs428]

I loaded up enhanced mGBA and it looks like it does not have zip file support. Is that correct?

 

[zerofalcon]

That's correct, no zip support right now. Zip support is only available with mGBA core using whatever instance of Retroarch frontend. I dont know if the official mGBA wii port supports zipped files.

I'll update to the most recent commit of mGBA to work with RA 1.0.2, I need to setup a new devkit environment to compile everything again, Linux installation crashed last week

That would be great, 1.3 still can't save custom resolutions.

 

[Demifiend]

Could i ask how to exactly change the resolution?, the games, while they run nice, they look a little too big for my configuration, and in the Options, i don't see how to change it manually (Like in VBAGX), so, could anyone tell me how to do that?.

 

[ngs428]

I am using the latest build 11-25-15. I do not have any audio. Same game on vbagx has sound.

Could someone please assist? I don't see any audio settings to adjust.

Thanks.
