This software is awesome, I love it! Sound works impressively good, the background beeping isnt as bad as I expected it to be.
Just made up a small argument booter to easly create a gbi.dol which boots with your arguments of choice, I dont know if anyone is interested in it, if you are then here you go:
http://www.mediafire.com/download/0xv6hqf9z3gdbvy
To use it just drop Extrems gbi.dol into the data folder, edit the main.c in the source folder with the args you want it to use and use the build.bat file to get out a new dol which basically is the original gbi.dol just with your arguments of choice, oh and you need to have devkitppc and libogc from the devkitpro installer of course.

FIX94, please excuse my ignorance, but I've never used those tools before. Does the script you wrote create a .dol that boots into a specific video mode of your choice?

you could do that yes, just check out the main.c and you'll see some arguments I did add as examples (these are my perfect settings for gb games to be in fullscreen for my tv card). You can look in the first post in the arguments section what can possibly be set.

You can trick it into using 240p by momentarily disconnecting the cable.
However, non-integer scaling in 240p is suboptimal.
480p is used if progressive scan has been enabled in a GameCube title.
Couldn't you have it behave like commercial games with a 480i selection screen by holding a button?
I'm still not convinced on the idea of deviating from near-universal Nintendo endorsed behavior.
Madden NFL 2002 is an exception, 480p was in its options menu.

It roughly matches Wii behavior.
Can we talk about something more interesting than video mode selection?

What kind of data is being transferred between the Gameboy Player and the Gamecube? Is it the entire ram of the gameboy or just certain parts?

No internal memory or registers are accessible, it's a capture device.

Hmm, that makes it sound like you're working on a replacement IPL.

The Game Boy Player displays games with altered colors doesn't it? Is it just simple brightness being lowered or is it not that simple and is that what the color gamut mapping is for?

I'm also interested in how (in)accurate the Game Boy Player is, as I own one myself but never hooked it up. For some people there seems to be a frame drop every couple seconds no matter the video mode.

The color gamut mapping is for matching Nintendo DS colors on a sRGB display. The Start-up Disc dims on its own.

This is addressed by framerate conversion, even on PAL 50 Hz.

Color settings are a fantastic idea I forgot. Get those oversaturated games to behave on backlit screens.

This is how Game Boy Interface looks like:
This is how it looks like without color gamut mapping and linear light:

This is brilliant, nice one Extrems.
I'd have guessed the 2nd brighter blue image above would have been the correct one.
I compared Castlevania in a DS and GameBoy micro with the Game Boy Interface and the Game Boy Player:

The photos don't do it justice, but you can see the colour matching effect really well. Also it scales better on my TV, perhaps as it's a slightly different resolution than the Game Boy Player, it certainly a little wider.
Extrems, just wondering why you didn't build it at 3:2 by default, as oppose to 4:3?

It would only benefit capture devices and VGA/DVI with 1:1 pixel mapping.

- Added low latency (buffered) version with 243p59.8261 video mode.
- Added ultra-low latency (unbuffered) version with experimental 243p59.7276 video mode.
- Changed all 60 Hz modes to have 486 active lines.

Both work great Extrems, and I'd say they're a massive improvement on motion blurring, thanks a ton!
On the ultra-low latency version however, chroma isn't being output when using S-Video, the picture is just black and white.
There's also some minor audio crackling with both low latency versions, but I'm sure you noticed that already.

It is there, you just can't decode it, due to the longer horizontal period breaking things.

I did say "with some glitches".

If 3:2 is the native aspect ratio of gameboy advance why wouldn't benefit everything?

Yeah, I've now got a ball without a weird shadow in Alleyway
Nice one Extrems.
Also I notice on the two low latency versions, where the OSD is gone you've added widesreen to gameboy games, toggling with X&Y.

We wish to maintain aspect on a 4:3 display (lowest common denominator).

It's the GBA's built-in scaler, I normally prevent you from using it because it hurts.

Ha yep.
I misunderstood on the aspect ratio, it's for the display device isn't it, and not for forcing the games into a different aspect.

Extrems, I'm curious, with some sort of video processor would bob deinterlacing allow for close to 60HZ framerate?
