Hacking Okay I made a Multigame Disc... Now What?

[BLBLB]

Basic question. What program do i need and which cisos should be installed for the wii to run and read multiple gamecube isos off one dvd?

You would need d2x 249, and NeoGamma R9. It should list the gamecube games on your disk in NeoGamma.

Thank you for a definitive answer

It would 've been better if you checked out the stickies. At least info therein really IS definitive.

(from the neogamma beta test thread FAQ)

Requirements for gamecube backup launching from disc with NeoGamma:
- A Wii with a backup compatible drive(if the wii is not white, it's not backup compatible, backup resistant white Wiis were sold since christmas '09, no backup disc compatible Wiis in the shelves anymore 1-2 months later). Easy test: In the latest NeoGamma, remove disc from the drive and select launch game from disc. You will get a read error. If your drive is too new, NeoGamma will say so. (after read errors when trying to read from disc)

- A GC backup compatible cIOS installed and used. For testing until it works, install cIOS37rev19, cIOS56rev20, cIOS56rev21 or d2x56v4(recommend). NeoGamma shows at the bottom of the screen which cIOS is used. If does not say: cIOS37rev19, cIOS56rev20 (slot 249), cIOS56rev21 (slot 249) or IOS249 (Rev 21004), you did not install the cIOS correctly.

- A GC homebrew compatible cMIOS. If you don't know which one you have, just install a the recommend one. cMIOS and MIOS always overwrite any MIOS or cMIOS you currently have installed. Waninkoko's cMIOS up to rev5(including) are not GC homebrew compatible. All of WiiGator's cMIOS should be compatible, but the original WiiGator cMIOS might suffer from stability issues. Well this should only affect the switching into GC mode, once a game is running, there are no differences. Recommend cMIOS: The one from this thread, because: It's NeoGamma compatible, still allows to play retail GC discs from disc channel without issues, it allows to use the debugger when booting with patched MIOS and it's just best tested and known to work.

- The correct options in NeoGamma:
Storage device: SD or USB using cIOS(the others should work too, but most people try everything, so...)
Gamecube Mode: internal (MIOS just boots MIOS like the disc channel does, external boots sd:/NeoGamma/GC.dol in GC mode)
Force Video: Disc(with component cables, you might need to try all options)
Patch Video: No(only relevant on import games with color issues)
Reloader, Backup plugin, Audio fix and Patched MIOS: Auto
GC Ocarina&debugger: No

- A valid game image written on the disc. Well the best way to find out if this is the reason why GC backup launching is not working at all is to create a clean new dump from a retail disc with SuperDump or CleanRip(newer than SuperDump and maybe better). Multi game discs are valid discs, but i can only say that the multi game discs created with MultiGame ISO Creator v3.5.4F+ work for sure. MultiGame ISO Creator v4.x is known to NOT work with NeoGamma! Important: If a game has audio streaming, then shrinking it will break the image. When audio streaming games are shrunk, they also need to be fstfixed with the 32K fix in order to work properly. The 32K fix in NeoGamma might be able to fix this on-the-fly, but it's still experimental. The expected error is that the game crashes or shows a read error when the game tries to play an audio stream.

- Being able to get into the actual GC loader, which requires "GC mode internal" + a compatible cMIOS. When it says "NeoGamma GC Backup Launcher" on top of the screen, only then it is actually executing GC code, only then NeoGamma will do anything more about GC games than Gecko OS or any other loader that just boots MIOS. (which won't even boot all retail GC games correctly right now)

- If you have a modchip, then multi game discs won't work with "GC mode internal", only single game discs. If you boot GCOS from NeoGamma, then GCOS is responsible for compatiblity, video modes, cheats and anything else.

- And last but not least: A good disc. Only use high quality media and never burn slower than 4x. If you believe you need to burn slow, then use 4x, all others try 8x,12x or 16x. And DVD+Rs need the booktype set to DVD-R(dvd-rom) on burning, or the Wii won't be able to read them. This procedure is called bitsetting, just google it. Especially if the games can't be booted at all and NeoGamma doesn't even switch to the internal GC loader, then it's a disc or .iso problem for sure.
