This is a sub-page of Mario & Sonic at the Olympic Games (Wii).
In addition to the 24 events featured in the game, there is an additional 10 events left unused, which makes up for a total of 34 planned events (which would've been the most amount of events in the series, surpassing the sequels on the same platform).
All of these unused events will throw an error on Dolphin upon loading, and will crash on console, but if the error is ignored, the event can be loaded.
Using the Gecko Code 04553404 XXXXXXXX on US versions of the game allows you to load into any of these events by selecting any event in Single Match Mode. Replace XXXXXXXX with the hexadecimal ID of the event.
The internal list of events are as follows:

Every unused event exhibits some unique quirks. Each of the event's introduction screens have a zoom blur applied for some reason. The Controls pages are all either left blank or reuses the controls pages for the 100m event. All the games are listed as supporting play with or without the Nunchuck. Almost all of these events have no 'gameplay', and just lead straight to the results when the event is started. In almost all the events, every player is a COM controlled Mario. The first COM controlled Mario (which the game thinks is you, the player), will end in 1st in each unused event. However, most of the unused events do not show his model, and in those unused events, the awards ceremonies that follow do not show his model either. In all unused events, the models for the medals do not exist either, thus, they are not shown.
Athletics - 800m#
The 800m race takes place in the National Stadium, the same venue as other Athletics Events like the 100m and 400m. There are seven pages in the tutorial screen, the first stating the control style, and the rest being blank. This event also has World Record (WR) and Olympic Record (OR) data, being set at 1:41.11 and 1:42.58 respectively, which accurate to the at-the-time WR and OR holders, Wilson Kipketer of Denmark and Vebjørn Rodal of Norway.
Starting the event immediately takes you to the results, where eight Marios finish at the same time of 3:23.647 exactly.
It likely would've faired differently to both the 100m and 400m events due to the real life 800m race being a middle-distance race, but it's unknown what the event would've played out like in the final game.
Aquatics - 400m Freestyle#
The 400m Freestyle takes place in the National Aquatics Center. It is the same venue as the other Aquatics events. The WR and OR for this event are 3:40.08 and 3:40.59, respectively, both belonging to Ian Thorpe of Australia.
Starting the event immediately takes you to the results. Four Marios finish in 3:23.647.
Shooting - Double Trap#
In addition to Skeet, there was also another planned Shooting event, Double Trap. This event would be ultimately cut, although would eventually make an appearance in the Nintendo 3DS version of Mario & Sonic at the London 2012 Olympic Games and reused in the 3DS version of Mario & Sonic at the Rio 2016 Olympic Games as a training event. It takes place at the Beijing Shooting Range Clay Target Field, the same location where Skeet takes place. This event reuses the controls pages from 100m.
The event finishes with eight Marios finishing with 0 points. Despite this, your Mario still celebrates and is rewarded with a nonexistent gold medal.
Rowing - Quadruple Sculls#
Rowing was also going to have an additional variant, Quadruple Sculls. The text at the event's starting screen claims it takes place at the Shunyi Olympic Rowing-Canoeing Park, however it is not the same location. In fact, it is somewhere completely different, not quite existing in the real world, but as a made-up location for a Dream event! This is confirmed by a sign at the start showing the message "DREAM BOAT", as well as flashing lights making up the word "DREAM". It's likely that this area wasn't intended for the event, as Quadruple Sculls likely would've used the same area as Single Sculls.
We can look around the area by moving the game's camera around, revealing more of this unused location.
The event seems to take place in a tropical area, with star-shaped and floating islands. Audience in large stands can be seen throughout the race. A volcano can also be seen in the distant background, too.
Near the end of the race, more flashing strobes make up the word "DREAM", with star-shaped stands housing the audience on one side and docked boats can be seen on the other end, featuring emblems of various Mario & Sonic characters on their design. Additionally, one of the docks has a unique pattern of suns, hearts, moons, and stars.
Unlike the other unused events, this one behaves differently. Rather than immediately being taken to the results up starting, the game takes you to a shot of several characters T-posing at the same point in the middle of an ocean. There is no music or sound that plays, and nothing happens. The game is not soft locked, however, as the player may open the pause menu and quit the game from there.
Dream Hammer Throw#
As for the Dream Events, there are six unused ones, giving us a total of 10 planned Dream Events that were supposed to be in the game, with only 4 of them making the cut.
The first of many is Dream Hammer Throw. It's just called "Hammer Throw" by the game, though we can infer it is a Dream Event by the unique Star icon for the game, as well as the otherworldly designs of these areas. It is listed as supporting both Wii Remote and Nunchuck, and only Wii Remote playstyles. There are 4 pages in the controls menu, with the first explaining the game's playstyle, and the rest being blank.
The game is immediately taken to the results upon starting it, with four Marios ranked 1st through 4th, each with 0 points. Unlike the previous unused games, now Mario's model is not visible anymore, being just as nonexistent as his medal. His voice can still be heard, though. In the Awards Ceremony, the podium intersects with the pipe.
Moving the camera around, we can see more of this game's scenery. It appears to take place in a barren wasteland during a sunset, where one end a sun setting can be seen, and on the other end the moon is visible too. In the center is an arena-like area, with four holes on each end, four totem pole-like structures on every other end, and a green pipe in the center. The arena is surrounded by a wire mesh fence, and on one of the ends is the hammer cage seen in the regular Hammer Throw event.
It's unknown what the gameplay for this event could've been considering where it takes place, which means it would've been much different from regular Hammer Throw.
Dream Shooting#
Dream Shooting is another unused event. The event takes place in a futuristic space setting, as can be seen by its textures. However, no models load into the game upon running, which makes this event appear as a dark void. Four controls pages are left blank, expect the first, which states the control style. The only models visible are the podium and confetti that appears during the Awards Ceremony.
Four Marios finish with 0 points each.
Dream Shooting would make an appearance in the Nintendo DS Version of Mario & Sonic at the Olympic Games.
It's unknown what the gameplay for this event would've been, or if it would play like its DS counterpart.
Dream Archery#
Dream Archery is another unused event, though this time it takes place in the same area as regular Archery. It goes to the results screen upon starting, like most other unused events.
Eight Marios finish with a time of 35:23.647. For some reason, Dream Archery's score is measured in time, unlike in points as regular Archery is.
Dream Rowing#
Dream Rowing is another unused event that takes place in the same location as Rowing - Quadruple Sculls. This game seems to be what the area was meant for, as this is a Dream Event. There are five pages of controls: 4 left blank, and 1 explaining the game's control style.
Unlike Quadruple Sculls, this event immediately takes you to the results upon start, like most unused events do. Four Marios finish with 0 points.
A similar Dream Event would appear in the DS version of Mario & Sonic at the Olympic Games, Dream Canoe, though it's likely that this event would've been completely different in terms of gameplay.
Dream Football#
Dream Football is another unused event. Despite showing a star as the game's icon, it takes place in an Olympic area. It uses the control pages from 100m and takes place at the National Stadium.
However, starting the event actually starts a broken version of the ending cutscene. The first half of it is a black screen. The other half shows your character in a T-pose in the middle of the Stadium, on a podium next to a stand for a trophy, with no trophy on it. The character that is on the podium actually respects your character choice, unlike defaulting to Mario. The game will then cut to the credits, where no images that normally appear in the credits show.
After the credits finish rolling, the game is taken to the results, with each character finishing with a time of 35:23.647. The character manually selected will appear first, with every subsequent non-human character appearing as Mario (though is not labeled as a COM). Player's ranks do not appear in the results screen of this event.
Football as an event itself would make its debut in Mario & Sonic at the London 2012 Olympics Games, albeit not as a Dream Event as originally planned.
Dream Basketball#
The last unused event, and last Dream Event, is Dream Basketball. There are six pages of controls for this game: 5 left blank, and 1 explaining the control style for this game.
The game takes place in a space-like area. Dense clouds cover the ground. Several planets and shooting stars can be seen in the distance, along with a moon, and a rotating space station.
Four Marios finish with a score of 0 points.
This Dream Event would appear in the Nintendo DS version of Mario & Sonic at the Olympic Games, though it would not take in space.
