Game Boy Interface

Does GBI work with Everdrives?

Yes

Hi all,

I've searched and can't seem to find an answer to this question. Are there input parameters which can be adjusted so the regular version of GBI isn't so excessively bright? I understand it was designed to match a GBA in daylight but when playing on a LCD it's way too much imo. The LL and ULL versions look much better. Problem is, they don't allow applying zoom to the image.

Thanks,
mario64

I too would like to know the answer to this. I saw the cli example Extrems posted with some gamma settings, etc, but I don't know the exact settings the LL/ULL versions use. I'd like to use GBI's PNG-capturing capabilities, but it's a shame I can't use them to capture the fantastic look of LL/ULL.

Thank you kind sir! I will try this when I get home. That argument's description in the first post didn't jump out at me as a possible solution, but it makes more sense now that I know the answer.

Hey Extrems, I'd like to thank you for creating this software, I've been using it a lot now to replay Golden Sun again.
The ULL version seems to work fantastic on my LG HD TV!
I am curious about something (please forgive me if this is already answered here), how come this software has some sound latency, while the original Gameboy Player software does not?

Hmmm, I'm going to assume that the original does have audio delay and you don't notice it, unless you have some way to prove that it doesn't. It's much harder to notice audio lag than it is video lag, light travels much faster than sound and all that.

I am not sure how I could prove this.. Maybe I could make a video and post it somewhere?
Either way, I am certain that the Gameboy Interface by Extrems has some latency in the audio over the original software.
I have been testing this with Golden Sun. The way I am testing this is by pressing 'A' to open up a menu. Opening the menu make a little sound, and that's how I measure the latency.

EDIT: On the main post it also says:
"Audio
no low-pass filter
32-64 ms latency"
So I am wondering why this is the case, basically.

EDIT2:
The sound is not coming from my own TV, btw. I have a receiver for that.

That's 2 to 4 frames of latency, because the regular version does some post-processing on the video which requires buffering at least two frames.

Screenshots aren't altered beyond image doubling, but gAMA and cHRM chunks are present. You can strip those to restore the look you're looking for in PNG viewers supporting color management.

This uses the ASND library, which has a large buffer. It mostly lines up with the video latency anyway. Something custom will be rolled out for ULL at some point.

Thanks for the explanation! I'll look out for it then.

Good point, I didn't realize he was talking about audio.

That's nice to hear, always performance first for ULL.
Nevertheless I'm excited about the prospects of a quicker more powerful replacement for Nintendo's UI. If not in GBI than somewhere like it.

Thanks for the info Extrems. I had never heard of PNG chunks, but I tried removing them from some of your screenshots (viewtopic.php?f=37&t=2782&start=25#p29959) using PNGGauntlet (a GUI for PNGOUT and others), but comparing the input with the output back to back in Irfanview with color management turned on, they look identical. Do you have a recommended viewer and/or chunk stripper for Windows that I could try?

Also, during my comparison I noticed something about the screenshots from that post: the bubbles in the one marked "nocms" seem... rounder. Is this simply due to the color mapping? Here they are overlapped: http://screenshotcomparison.com/comparison/202231. Thanks for your time.

Those aren't screenshots made by GBI, it's video capture.

Hi all, so I'm new here and just want to be 100% sure about some stuff. I have a GameCube and gameboy player. So All I need is a sd launcher... no disc required right? And what's a good recommendation for the SD launcher? Thanks!

[novenary]

SD media launcher is a disc and comes with a (poor quality) SD adapter. You can find slightly better adapters known as wiisd if that causes issues.

[cocklederry]

Not 100% certain this is the place for this, but I've been meaning to ask for a while now, is there/will there be any inclusion of something like the Super Gameboy's special palettes? Like in Donkey Kong or Pokemon where it sections off portions of the screen for different palettes?

Because I think that would be really swell.

[bobrocks95]

I believe extrems has said somewhere in this thread that SGB features can't be added.

[novenary]

The gameboy player is literally a gba with a capture device. The extra SGB features are part of modifications made to the gameboy hardware to take advantage of color TVs but the GBA doesn't support those, so it's not possible.

[Extrems]

• Added temporal/spatial dithering.
• Added color matrices by Pokefan531.
• Added TPL overlay support to wiiload server.
• Changed default color matrix to Pokefan531's.
• Changed default gamma to 2.2.
• Optimized NormalNx filter.

For low latency version:

• Added rumble, disabled by default.
• Added USB Gecko wiiload server.
• Added Xboo Communicator.

For BIOS/ROM dumper:

• Improved transfer robustness.

good job!

OK first time here and new to most of this homebrew stuff. Have GC and GB Advance Player. Currently using with Framemeister. After seeing video on Youtube by 'My Life in Gaming' looking to use Game Boy Interface to play back GB Advance games.

Can someone tell me what files to put on the SD card? Not sure if doing right or if the SD card reader I picked up on Ebay actually working. Already have the Action Reply disk in but doesn't see the SD card.

Simple enough is what files go to the root of the SD card.

Big thanks in advance

[Extrems]

Your problem likely stem from using an SDHC card. These aren't compatible with the Action Replay/SD Media Launcher software.

[Xaranar]

I've just noticed, how come the rendering intent argument has disappeared and I'm stuck with the washed out colours?

[Extrems]

You're not, it changed for the color matrix option.
