You're missing a line feed after --no-osd

So exactly what do I put after "--no-osd"?

The ASCII line feed is 0A in hexadecimal.

If youre enabling it right... are you on the latest version of GBI? Do you use any controller adapters or extension cables? They could be a problem.

Edit: iirc Regular GBI has rumble on by default so that could be a place to start testing.

Yes I enabled it both in Swiss or with cli file, I tried only the last version since I don't know where to find old versions.
I even tried to boot directly GBI instead of Swiss, no changes.
I don't have any adapter or special cable, just an official Nintendo GC controller (one of the last batches produced by Nintendo).
What do you mean GBA rumble? Can I use my GBA + cable link + a game with rumble?
That would be awesome, I have to try that

This is indeed a thing.

I got it to work, thanks so much!

Is there any advice or info you could give on what to try, possibly, to fix the display chain resycn issue? I'm using original component cables on my Cube, if that tells you anything.

I tried the GBA + cable link + a game with rumble, but still doesn't vibrate...
I also tried other gamepads, no changes
Can it be a problem with the way I am loading swiss or GBI, or my Gamecube region?
I'm using PokeLoad on a japanese gamecube, along with a generic SD Gecko.

I''m not sure what your problem is, sorry. It could be pokeload or the JPN Cube, but I think people have reported both of those implementations working.
As for the GBA cartridge rumble... it can be kinda finicky so i'd recommend when getting rumble working you test with a known working controller. Sorry I couldn't help and good luck!

No problem I understand, thank you for helping
Actually everything work really great expect the rumble feature, that's why I was wondering if I could be doing something wrong
I tested all my 3 GC gamepad that have rumble in other games but still no luck.
I think I will buy a cheap gameboy player official disk to see if it works or if there is an issue with my GBP, but anyway even without rumble this software is still amazing.

For low latency version:

• Tweaked input viewer.
• Changed some argument semantics.

So, I decided to make some videos to demonstrate a couple of different systems/emulator with my "demo" program to give you an idea of what the LCD timing/display is like. For all of these, I used height=32, move=48, and pressed select and start to disable the palette cycle and reset it back to 0. I apologize in advance on the quality of the videos. Most were recorded on a Nikon Coolpix L27 at 1280x720 at 30.017 fps. The 3DS videos were recorded on a cheap webcam at 640x480 at I'm not sure what frame rate.

GBA SP - https://streamable.com/3q05f
NDS Lite - https://streamable.com/b2r5h
3DS (no ghosting) - https://streamable.com/gkig7
3DS (average ghosting) - https://streamable.com/8qof7

GBI v20180204 - https://streamable.com/nv4ce
GBI LL v20180204 - https://streamable.com/x678x

The GBA SP is how it's supposed to look. For the NDS Lite there's a glitch frame every 176 frames or ~5.8633 seconds. Both 3DS variations seem to render correctly, except the average ghosting's colors are off. They're not nearly as bad IRL. The webcam apparently has a color skew as the last bit of the video should show equal intensity red/green/blue.

The Gamebox Advance is a Gameboy Advance clone based on a GPSP emulator (AFAIK) and clearly renders entirely wrong because frames aren't at all merged. VBA GX seems to have a glitch frame every ~435 frames or ~14.49 seconds--I'm not entirely sure how regularly they are compared to the NDS Lite.

For the official software (which I have as Full Screen, Normal Filter), there's a glitch every ~139 to ~149 frames or 4.63 seconds to 4.9638 seconds. Finally, there's a sort of color wobble with GBI every ~142 frames or ~4.73 seconds. Meanwhile, GBI LL every ~307 frames or 10.22753 seconds has a similar glitch to the NDS Lite. The last three seem to have a few to several frames variance.

The only other major thing is to note that if you set the height down to 1, it's apparent there's a pattern that appears mid-image but not at a consistent point. I'm not sure what this is, but it seems pretty consistent across at least a few of the different systems I tried (except the Gamebox Advance). Maybe it's because of changing the palette mid line? Anyways, this is what it looks like through a few heightmap images:

Oh, and sorry if this is considered threadjacking. I just find it interesting from the perspective of comparable accuracy. In real games, I don't think any are stupid enough to do what my demo program does. I also posted this out of curiosity if everything else would bothered to try got similar results.

Edit - Added 3DS examples. I'd really like to have a much faster camera (and display) to see just how much of the blurring is a result of the monitor/lcd vs what's visually received/interpreted. *shrug*

The color wobble is an artifact of the frame rate conversion. It's basically spreading the glitch frames over time.

I've been using the new version and it seems the audio glitch is not related to the reduced delay. I still hear it on pause screens. However, with Wario Land 4 specifically I was having a real hard time even playing the game with the lower audio delay. Most times the game would not load at all and other times it would load but crash later on. It's the only game I've experienced that with, so it may not be related, but I've had no issues with the latest version. So anyway, I guess my point is that the audio clicks and pops do not seem to be related to the reduced audio delay you implemented.

I've checked and it definitely made it worse.

For low latency version:

• Added background color setting.
• Added video buffering setting.
• Renamed to speedrunning edition.

For ultra-low latency version:

• Folded into speedrunning edition.

Some more playing around, and for the new merged gbisr, I get an interesting rolling red/green/blue thing every ~10.2 seconds. Options were "--delay-video=0 --background=#0080FF --poll=7". I think that "--delay-video=0" is the cause. Not sure if it's important or interesting to you, but figured I'd post another video.

This is expected for NTSC 240p, you need to use the custom video format to prolong the cycle.

The downloads seem to be broken.

Yeah, I lost power. It's back now.

I finally got a Gameboy Player Disk to test the rumble feature, and as expected the rumble feature works perfectly with all the games supporting it.
But still no luck with GBI, no rumble at all no matter which version I use and whatever I try... So there might be an issue between GBI and my system somehow

Is there any limitation in GBI depending of the region of the GBA game or the GC hardware ? (for instance JAP or EU instead of US)
Because that's pretty much the only thing I see that could be causing the issue, since there are no problem with the hardware or software themselves.

There are no differences between hardware regions whatsoever.

Streetwalker wrote:There are no differences between hardware regions whatsoever.

Even for the GBA games ? I mean how does the rumble support works, does it enable it for every games just in case they need it or does it detects the rumble function for each compatible game depending of their ID?
And I am not stupid, I know that there is no hardware difference, I am talking about the software side of things and the way GBI manage different regions games for instance
It really makes me confused on how this bug can happen, since I am 100% sure I am using the right parameters for the rumble, on a recent version of GBI, and since it is working perfectly with the official GBP Disk.
So it's obviously not an hardware issue, nor a wrong configuration, and everyone here is telling me it's not GBI either, so what, am I becoming crazy ?

Edit:
So I tested the US version of Drill Dozer with my EZ-Flash IV, and the rumble isn't working for this one too, so indeed it's probably the same with all games region.
Can anyone test Drill Dozer US on their GBP with the last GBI version launched with Swiss and tell me if it works for them ?

The same as the Game Boy Player Start-up Disc: By looking at the screen for the Game Boy Player logo, inputting a button pattern while it's visible, and then doing a handshake and polling for rumble over a serial link.

Stremon wrote:I am talking about the software side of things and the way GBI manage different regions games for instance

GBI has no knowledge of the game.

Stremon wrote:everyone here is telling me it's not GBI either, so what, am I becoming crazy ?

It's possible it's GBI. But I can't do anything if I can't reproduce the issue.

Working as intended for me.

I'm having the exact same problem. With both 007: Agent Under Fire and SSBM, loading Swiss and latest GBI and the rumble doesn't work. SSBM and latest GBI direct boot and rumble works. And of course, official GB Player software rumble works. So, my guess is that somehow Swiss is interfering? I've tried with GBI and GBI SR on Agent Under Fire with Swiss enabling rumble. But GBI non-SR should do rumble by default, so either way it should work but it doesn't. So, it's not merely a bad parsing.

Not sure if any of this information is useful. Even if Extrems can't reproduce it, at least i can recommend the workaround of directly booting GBI. Hopefully that'll work for you too.
