[GC] Mario Kart: Double Dash!!

[Kraid]

About the game (IGN.com)
The king of kart racers has returned with Nintendo's Mario Kart: Double Dash on the Nintendo GameCube. Mario, along with Luigi, Peach, Baby Mario, Baby Luigi, Wario and more, are back for more multiplayer, single player and versus action. The new Mario Kart features updated graphics with detailed character models, and colorful interactive racing environments. For the first time, two characters ride in a single kart as one drive while the other uses items, opening up the possibility for two-player co-op racing. Along with the classic four-player competition, Mario Kart: Double Dash offers a new eight-player mode, where players can link multiple systems for a new level of multiplayer kart racing.

Emulation Status & Speed

Issues:
• None.
  
  Emulation Speed
• Right now the game requires a very good CPU
  

Additional Information
I noticed that in older rev's of Dolphin, disabling "Use safe texture cache" slowed the game down very intense.

If you use the X64 version of Dolphin-emu. You can play at 50fps, but you don't start the next race.
Good Pics!!!

Some code for the hanging. We are now blessed with function names unlike for most games. This is for the NTSC version:

Code:

# It jumps around between these functions

The DHCP functions is about the LAN play ability. I don't know what SO in the SO... functions stand for or what they do. They may have something to do with the broadband adapter too. The other function names are SOInetNtoA, SOInetNtoP, SOSetResolver, SOGetResolver, SOStartup, SOCleanup, SOSocket, SOClose, SOListen, SORead, SORecvFrom, SOWrite, SOSendTo, SOSetSockOpt, SOFcntl, SOGetHostID, SOPoll.

Perhaps we are not properly telling the game that we don't have any broadband adapter connected.

Do you mean that it's fixable now?

I was playing last night, made it to the second track but was dead tired to try another one. It had missing 'carts' from what I recall, but that could just be the settings I was using.

[rene mauricio]

Crap. I just tried this again and while I can see the carts now, it will not pass the first stage >_>.

[Der_Kater]

I was able to make the whole all cup tour with the 3404 version.
Thank you very much for fixing it!

Now the Menus are running at 120-145fps, this is fixable with the framelimiter, but I have black borders right and under the screen.
Any Ideas how to fix it ?

PS.: Every time I run Dolphin the framelimiter sets itself off. Is that normal ?

thx to death2droid, this is available in all version 3408+


@ topic : only ntsc version working ?

[nosound97]

Both versions probably works, but intro video works in PAL only

tried it today : second gp loaded without any problem on pal version
