You shouldn't be too hard on FIX94. I bet he even with your hint he had a hard time implementing audio streaming. And don't blame him for asking for donations. He's a college student, which hasn't got that much cash, while you are probably a software engineer with a huge wage.

I was wondering if anyone has any idea why I am unable to get Mario Kart Double Dash BBA emulation to work when playing the game on my Wii and Wii U at the same time. I turn on both systems, go to LAN mode on both systems, but it just says "Looking for Nintendo Gamecube systems" on both systems until the 180 seconds runs out.

Here are my logs on the Wii and Wii U when I try running them individually.

Any help is much appreciated! :D

Your router possibly doesn't support multicast over wifi.

Huh. I had a feeling it was a router problem. Oh well, it's not a big deal if I can't do a lan connection. Thank you for the response.

I do not own nor have access to a copy of the GameCube version of Metroid Prime so I cannot test if this has already been implemented, but I discovered an few AR codes used for eliminating visible culling for the Oculus Rift and wondered if such a thing would be useful as part of a game-specific widescreen hack.

If the game is properly configured to render with a wider FOV there's no need to disable culling. It's only required for the Rift because they want to see everything regardless of the FOV.

Well like I said, I didn't know if the widescreen hack worked in the GameCube version of Metroid Prime/2 Echoes or not. I'm guessing it works flawlessly on both?

I will say though, unless the culling got fixed in newer revisions of Devolution (I haven't updated in a while because I want to redo my Wii homebrew setup on a 128GB flash drive anyway), I will say that Rogue Leader could totally use a culling AR code - too bad there isn't one (yet).

What you are talking about is clipping, not culling.
I don't think the "standard" widescreen patch has any affect on Metroid Prime. It's not really a candidate for widescreen patching due to the 3D HUD using assets that are designed for a 4:3 display/layout. If the HUD gets squeezed it looks silly and breaks immersion. If it gets left at the original size with a wider FOV, special effects (targetting, scanning etc.) don't line up properly.
The standard wide patch also does not change the FOV that the game thinks is being used for the viewport, hence the clipping issues. Disabling clipping is a ridiculous fix for widescreen issues; it forces the entire scene to be sent to the GPU for rendering, regardless of what is within the FOV or even behind the camera.
Any game that has clipping issues with the default widescreen patch must be using its own clipping algorithm (likely for performance reasons) so there is no chance of a generic fix.

Oh, I think you misunderstood me - I wasn't thinking about a generic fix but the theoretical idea of a game-specific fix for Rogue Leader, and was wondering if something like that Metroid Prime Oculus code got made for Rogue Leader if it'd be of any use.

Adjusting the Y res to 336 (448*3/4) gives a more accurate result since it requires no rounding.

I have a favor to ask you, tueidj. Would you please enable BBA emulation for Homeland(GHEJ91)? I saw the latest version of Devolution supports BBA emulation for LAN play so I would like to check if it works for the game and I tried to, but I found modem emulation is enabled instead of BBA (Homeland doesn't support modem).

BBA emulation only supports LAN play, Homeland requires an internet connection.

That was true in the past because it required matchmaking server for connecting to other servers, but there's a way to connect without it someone found after the official matchmaking server was closed and it became playable in LAN. So I'd love to try it and make sure whether it works or not.

That doesn't change the fact that it uses a different style of communication that is not supported.
LAN play = multicast/broadcast traffic, no DNS.
Internet play = unicast w/DNS.
It will not work.

Actually it maybe doesn't require DNS (set server's IP address directly) but unicast seems true. That's disappointing.
However, I have come to think I'd like to check and see with my own eyes that it doesn't work, please enable BBA emulation anyway?

Then, is it possible to disable modem emulation for the game that is not supported? Since only PSO supports modem adapter, there's no need to enable modem emulation for other games.

Then the game would think nothing was plugged in, I don't really see what advantage that has.

I was just impatient with enabling the function that is not available when I'm playing that game, so never mind, I'll use gamecube or something. Thank you anyway.

Although it is by the way, modem emulation works fully using PSO and BBA emulation works using Kirby Air Ride (it sometimes stops but it's probably caused by wireless connection). I'll try Mario Kart: Double Dash!! later.

So I tried to get LAN working with Double Dash on two Wii Systems I have. I haven't gotten it to work. I checked my network on my computer and both Mario Kart: Double Dash systems were connected to the network. They just appear to not be communicating with each other. Is there something else I'm suppose to be doing to get them to work? Both Wii's are connected to the same network through Wifi. I originally tried it with my Wii and Wii U and that didn't work so I decided to try it with two Wiis and that didn't work. Is there something I have to set up /enable with my router to get it to work?

If they can both be seen by your PC (showing up as Mario Kart Double Dash devices), they should be able to see each other (assuming your PC is also using wifi). Look for anything regarding uPnP or multicast in the router settings. You could also try connecting one wii (or both) to a PC running Dolphin with BBA emulation.

Well connecting one to the PC through dolphin worked. The PC was a wired connection and the Wii was wireless. Still can't get it to work with just two Wiis. Would distance be a factor between the systems and the router?

I guess it could be if the wifi signal was weak enough to cause it to drop down to only 1 or 2 mbps.
