How to play multiple disks in WiiVC for Gamecube?

The new Wii VC injector allow us to play injected gamecube games on the Wii U, there are few games in GameCube have multiple discs such as Metal Gear Solid the twin snakes, Resident Evil, Tales of Symphonia ets.
so what should i do when i reach the the point that i need to insert Disc 2?

thank you

 

thank you for your reply.
i can't read 220 pages to get the answer but i just read few random pages and i know how the injector works, my problem is during the game it will not switch to disc 2 no matter what button i pressed i'm just stuck at the change disc screen.
i'm sure disc 2 is included in the game as i did it with wiiu usb helper to avoid mistakes.

 

i'm pretty sure i have the latest nintendont for vWii, but i'm not sure if the injector was disc2.gcm, as i said i used wiiu usb helper to do it, but either ways the wiiu usb helper should do those things automatically and if the file is wrong it should give me an error right? but everything work smoothly.
anyway i will check the files when i go home tonight to make sure, but i may need to reinstall the game again, will that affect the safe files?

 

Thanx I was wondering where the safe files are lol I forgot its using nintendont.

I was too lazy to use the script but it looks like I can custmize a lot of things using it, will try that thanx.

 

It worked, after i went with the script and inject the game again it still have the same problem, then i just replace the .dol file to be 100% sure i have the latest update and it worked, strange i thought i have the latest .dol as i installed it less than a month ago from the main site.

thank you guys
