What about the emulators already built in to the Wii?

Well considering that the original rom was about 31.8mb after removing the padding and the Wii version is about 20mb, they obviously removed some stuff and made it external to make it work.

After extracting the files that are in the file that contains the rom, I see several .T64 files with names that correspond to the blocks in the games as well as several files which appear to be some of the animations.

When people tried to inject the PPL rom into sin & punishment, you could not go beyond the Press Start screen.

When you press start there was a video which I assume is the reason it would not play.

It looks like that intro movie is in a separate file as is a lot of the video, probably all videos in the game are separate files.

Computer and other console emulators often use things like speed hacks and game specific hacks for compatibility that usually involve patching the game ether in the devices RAM or in a temporary file. The goal being to get everything you toss at it to run decent.

Nintendo dose not need its emulators to patch its ROM's on the fly, it can just patch them manually before putting up a new game.

There are also emulators that are designed to be more accurate without using these cheats. The goal being to get such emulators as close to hardware accurate as possible

Such emulators require more systems resources and are more difficult to develop. The wii is powerful enough to run anything close to or below SNES level without cheating but things around N64 level may be too resource heavy for the Wii to run without cheating

there is no reason to try to get Nintendo’s emulators running different ROM's because even though it may not seem like it the homebrew emulators are better at running every single ROM than the ones made by Nintendo because that is what they are designed to do.

Although it may prove useful to reverse engineer them in order to see what approach they took at fixing an issue in some cases
