For unknown reasons, a Gecko Code on the Wiki for Rayman Arena that was
meant to help with widescreen patches. This doesn't actually change
anything about the game unless you enable Dolphin's built-in widescreen
hack, where it will cause enemies and whatnot to render on the edges of
the screen. This is because it patches out the culling function in the
game, which coincidentally is also the cause of the hang in Dolphin.
With "Store EFB Copies to Texture Only" set to True (the default setting), areas of Excite Truck appear darker than on console. For example, in Sylvan Glen under the Bronze cup, all of the trees appear very dark, nearly black. On console, this does not occur.

Setting EFBToTextureEnable = False fixes this issue and does not appear to introduce any performance impacts, so I am recommending that this be disabled by default for this game.
Apparently MMU is no longer needed in these titles. All 3 booted and
played into gameplay in the latest builds without issues, and disabling
MMU results in a very slight, but noticeable performance boost.
At least on Android, SyncGPU has really bad performance compared to
single core. It's less stable too - I get fatal GPU desyncs in
Pokémon XD using the default settings.
This Pull Request updates N64 INIs based on what I know about various
behaviors since the last time we updated it. This should result in more
sane settings for Mario Tennis and Super Smash Bros. while still
preventing the out of memory crash due to the tremendous amounts of EFB
copies.
