Homebrew mGBA official standalone Wii port

Thank you. It worked!

Glad I could help

Game Boy and Game Boy Color emulation seems to have stopped working on Wii builds after 0.5.0 (get a code dump when trying to load a ROM).
I can't seem to find anyone talking about this. Can someone here confirm that I'm not crazy? I'm using pixel accurate video with 240p mode.

I have experienced it myself, but strangely some of my games do work. There's this https://forums.mgba.io/showthread.php?tid=575&pid=1347#pid1347

Odd, I've only ever tested it with Link's Awakening and Ghost Babel. Both worked prior to 0.5.0 ( or at least they booted).
If someone could report this to mGBA's github that would be nice (sorry, I don't have an account there).
EDIT: Never mind. I submitted an issue.

Why didn't people report the broken GB/GBC properly or in a timely manner to Endrift? It's not that hard to make an account you know.

Try starting a GBA game first and then a GB/C game. Or try older nightlies from a few weeks ago, I know GB games worked fine in some of those.

For the same reason you didn't?

I've tried that with past nightlies with no success. I'll test with the latest later today.

I believe I did report the issue with GB/GBC games.
More so, I think I posted in the forums about certain GB games with GBC compatibility only showing up in black and white.

I think those are games with special palettes and modes like Donkey Kong and Kirby's Dreamland 2

Well, endrift responded and said it was fixed along time ago... I found out the issue was caused by keeping my old config file from previous builds. Deleting it and letting the emulator generate a new one fixed the issue.

the_randomizer is a waste of time and a known beggar, so don't mind him

nightlies should work perfect, it was only 0.5.0 that had the problem with gbc

I just tried this with the 20/12/2016 nightly and I still got a code dump. I tried erasing all the content on the SD:/mGBA folder and the problem persisted.

I wrote yesterday on the mGBA forums and Endrift responded, and commented about a possible commit issue.

EDIT: Endrift just answered again, and this issue got fixed! Endrift is great.

That's awesome!
I found out later that my config change might have been a red-herring since I started receiving the crash again (not sure why it started working randomly for a short period of time).
Everything is working great in the newest lightly!

 

[Maeson]

Great to hear that, I'll update now too!

Hey folks, is there any way to get a "stretched" mode that maintains the proper aspect ratio? In 4:3 or 16:9, whichever would be easier/more practical. Using pixel accurate mode is unfortunately far too small on my TV, and I don't mind the blur from the "Bilinear (Pixelated)" filter much. I've been playing on stretched mode, and the emulation is fantastic, but the weird aspect ratio is a bit annoying.

Thanks!

 

[TheBeverage]

Okay, I see now I missed some discussion on the prior page. I guess the question would be then, using the
[ports.wii]
stretchWidth=1.0
stretchHeight=1.0
configuration, what would the proper values be to match the original GBA aspect ratio? Thanks again!

EDIT: Did some math, and the closest approximation could get to 3:2 within a 4:3 640x480 frame was 640x426, and 426 is roughly 88% of 480, bringing me to this:
[ports.wii]
stretchWidth=.88
stretchHeight=1.0
It looks good enough from my end!

Hi guys does anyone have wad foward for mgba that can send me by p.m. please? thanks

Can mGBA run Metroid: Zero Mission at 100% speed and a stable 60 FPS? Because VBAGX can't, and I really need a super-smooth performance to pull off all the sequence-breaking tricks.

It can, every commercial GBA ROM that runs, runs 100% on Wii. The best part? mGBA doesn't use speed hacks or frameskipping like VBAGX, it's very well optimized

It's "--scan-mode=non-interlace", Enhanced mGBA only.

How do I add this? I've tried several ways but it doesn't take effect, also, do you know how to switch borders?

 

[SuperrSonic]

Are you using the hbc to load it? Just add it to the meta.xml under arguments. For switching borders it's all on the GBI thread, "--overlay" let's you change the default path, and "--overlay-id" is the texture id in the tpl. I find BrawlBox pretty good for management and keeping track of which texture is which.

These are the settings I last used.

Spoiler

<arguments>
<arg>--network</arg>
<arg>--aspect=4:3</arg>
<arg>--intent=saturation</arg>
<arg>--contrast=.80</arg>
<arg>--input-gamma=1.</arg>
<arg>--output-gamma=1.</arg>
<arg>--zoom=2.5</arg>
<arg>--filter=normal2x</arg>
<arg>--overlay-id=0</arg>
<arg>--rotate=0</arg>
</arguments>

If you don't ever use a 3DS as controller you should not bother to enable network.
