A Japanese prototype of '''Milon's Secret Castle''' for the Famicom.

==Notes==
*Game automatically goes to Game Over screen when getting the crystal after beating the first boss. However, it is possible to bypass this by killing the boss when it's at the right edge of the room and letting the crystal fall on you while pressing right by the closed door
*Using the above glitch it's possible to explore the second floor. Upper left level is fully playable, upper right level resets the game, and the well cannot be entered
*No pause function.
*No "finger speed" easter egg on the title screen.
*An automatic demo starts after 4 seconds on the title screen that plays up until the first boss.
* Miscellaneous Notes:
** Game is emulatable: Yes.

3D Challenge was an early demonstration of the Nintendo 3DS' 3D capabilities. It was one of three Nintendo 3DS demos that Nintendo showcased at a private media event during E3 2010; but was not accessible from attendees on the show floor.
==Notes==
This demo has little documentation from the event. Here is a hands-on review from an author at NintendoWorldReport.

A localization prototype for the unreleased PAL NES version of '''''Exerion'''''.

==Notes==
* Similar to Jaleco's overseas version of City Connection, this version of Exerion is spruced up from the Japanese Famicom version. It has larger PRG & CHR ROMs and the extra space was used for better graphics and music.
* An NTSC US version of Exerion was submitted to Nintendo lotcheck on March 17, 1989. It has the same CHR ROM as this PAL version, so the PAL version is likely from roughly the same time.
* For years the only available ROM for this game was a NintendoAge release with a defaced title screen and the Nintendo licensing text removed. Possibly due to confusion originating from the NintendoAge release, the game is currently DAT'd in the No-Intro romset as "Exerion II (USA) (Proto)" despite being a PAL localization prototype of Exerion, not a sequel. Patches for the NintendoAge release that restore the title screen were created by MrNorbert1994 and Bro3256 which byte matches with the ROM dumped in 2017.

An early prototype of the unreleased Akira for the Sega Mega Drive.
{{Tcrf link|Akira (Genesis)}}
==Notes==
* This specific build was burnt on two PCBs, one working and one partially working. Upon dumping both PCBs, it was discovered that one of the later EPROMs on the non working one was a duplicate burn of one of the first EPROM chips but is otherwise exactly the same as the working PCB. The working prototype was dumped multiple times with a Retrode 2. Each dump was consistent in terms of calculated checksum. The EPROMs that make up the working prototype were dumped individually with an EPROM programmer to ensure that the EPROMs had no issue.
* Approximately 65% of the ROMs contents can be accessed within the game itself according to a code/data log analysis. The other 35% is non-null data containing unused sprites and other data.
* Developed by Black Pearl Software in 1993 with an intended release for 1995.
* Earlier than the demo present at the Summer Consumer Electronic Show of 1994 (SCES 1994).
* A lot of music cues are present in the sound test but are unused by the game itself.
* None of the levels can be completed in this prototype.
* You can go back to the level select at any time by pressing start.
* Level 1K/1T lack enemies.
* The game is prone to crashing around the starting area on level 2T.
* The cutscene that plays before 1K/1T are the same.
* There is no cutscene before 4K.
* The game freezes upon loading into the fifth stage.

==Levels==
* The levels are categorized in the game by whenever you play as Tetsuo (T) or Kaneda (K). That means there are two Level 1s (Level 1(T) and Level 1(K)), two Level 2s (Level 2(T) and Level 2(K)), etc., with the only exception being Level 5, which only has a Kaneda variant but is still referred to as Level 5(K).
* The levels can be selected on a map in any order, and each level has a preview picture and a short description for the stage that follows the plot of the movie.
* There are no sound effects whatsoever.
* Pressing '''Start''' brings you back to the level select.

'''Motorcycle Rumble/Gang Leader - Level 1(T)/Level 1(K)'''

* The only level pair that is practically the same, with the only difference being the character you play as. All you can do here is turn left and right as well as punch.
* The cutscene that plays before Level 1(T)/Level 1(K) are the same.
* There is no music.
* There are no enemies.
* The level loops endlessly, and thus cannot be completed.

'''Army Hospital #1 - Level 2(T)'''

* '''Up/Down''': Move up/down.
* '''Left/Right''': Aim hand, strafe left/right.
* '''A''': Shoot energy blasts.
* '''A + B''': Use item.
* '''B + Left/Right''': Select item.
* '''C + Left/Right''': Turn left/right.

* The first of two first-person stages. In them, you control Tetsuo through a military hospital almost in the style of ''Doom''. You can turn around, strafe, and shoot out Esper energy blasts. There are also doors you can open by just walking up to them, as well as enemies you can blow up (and quite graphically, too).
* Three keycards are required to progress through the level: a bronze one to enter the Records area, a gold one to enter the "No Entrance" area, and a red one to enter the Restricted area. The Restricted area is a small room decorated with childish illustrations reminiscent of the movie's nightmare scene, and seems to be where the level would've ended. There isn't a way to complete it, though.
* The music that plays here is the same as on the title screen.
* If Tetsuo is adjacent to a medical curtain decoration and turns to face it, the game will crash.
* Many areas/rooms are labeled, such as the Cafeteria, Observation Room, and Barracks.
* The enemies will only move if Tetsuo bumps into them, and will never attack him. Soldiers are an exception: they either walk in place or allow Tetsuo to noclip into them.
* Four items can be picked up in the initial hallway: one PSI power pill, and three food items. The items can be used even though there's no way for Tetsuo to lose health or psychic power.
** Using any of the healing items will display an animation of Tetsuo eating.

'''In the Sewers - Level 2(K)'''

* '''Left/Right''': Move left/right.
* '''Down''': Crouch, exit background layer, climb down ladder, pick up item.
* '''Up''': Stand up, enter background layer, climb up ladder.
* '''A''': Shoot gun/Punch.
* '''A + Down''': Block
* '''B''': Jump
* '''C''': Kick

* The first of two platforming stages. In these, you control Kaneda in a very side-scroller fashion. He can jump, climb ladders, kick and shoot a gun. Shooting the gun drains your ammo, which you can refill with items. Once you're out of ammo, your gun gets replaced with a punch and the ability to block.
* There's also an interesting mechanic in this level: the ability to switch between the background and foreground layers through door-like holes on the wall.
* No music plays in this level.
* Pill: Restores your Str. (health)
* Uzi: Restores your ammo.

'''Army Hospital #2 - Level 3(T)'''

* The second first-person level. Very similar to the first one, but with a few noticeable differences.
* There are no enemies present in the stage.
* The area/room labels aren't present.
* The bear seen in the movie's hallucination scene can be found and fought in the central room. Once the bear is killed, Takashi appears and vanishes.

'''Flight to Fate - Level 3(K)'''

* A side-scrolling bike-escape maze sequence with a rather impressive pseudo-3D effect. This is one of the few levels to actually have sound effects: a sound for shooting, a sound for bullets hitting metal, an explosion sound and a "NO!" soundclip for the enemies. Shooting the bike gun drains your ammo.

'''Olympic Bridge - Level 4(T)'''

* This one is an isometric stage starri
ng a freshly broken-out Tetsuo. All he can do is move around and shoot out Esper energy waves. However, he can charge up those energy waves to make them even deadlier.
* This stage suffers from tile scrolling bugs.
* Both this stage and Level 4(K) share the same music, which is different from Level 2(T) and Level 3(T).

'''Platform Action - Level 4(K)'''

* The second of two platforming stages. Takes place on the famous elevator.
* Erroneously shares the same cutscene as Level 3(K).
* This stage suffers from tile scrolling bugs like Level 4(T).

'''Psychic Stormwall - Level 5(K)'''

'''Player 1 (Kaneda)''':

* '''Left/Right''': Move left/right.
* '''Down''': Crouch
* '''Left/Right + Down''': Crouch to left/right.
* '''Up''': Jumping (can cause the game to freeze if let go).
* '''A''': Punch
* '''B''': Block
* '''C''': Kick
* '''C + Up''': Jump kick.
* '''C + Down''': Crouch kick.

'''Player 2 (Tetsuo)''':

* '''Left/Right''': Move left/right.
* '''Down''': Crouch
* '''Left/Right + Down''': Crouch to left/right.
* '''Up''': Jumping (doesn't cause the game to freeze like Kaneda).
* '''A''': Punch
* '''B''': Block
* '''C''': Kick
* '''C + Up''': Jump kick.
* '''C + Down''': Crouch kick.

* This level was meant to be the climactic showdown between Tetsuo and Kaneda from the movie. However, you can't really do much here, because the game freezes upon loading into the fifth stage. This can be fixed with Action Replay code 00D5F4:4E71.
* In terms of gameplay, this level is similar to the platformer levels, but with one boss instead of multiple enemies. Players 1 and 2 take control as Kaneda and Tetsuo, respectively, and pummel each other until one loses enough health. Tetsuo mutates once this happens, while Kaneda stops getting staggered by attacks.
* Once Tetsuo mutates, Player 2 is unable to control him, and starts cycling through a set of actions. He walks forwards then backwards, jumps in place twice, attacks with a flesh whip from his hand twice, spits slime at Kaneda, and uses a similar whip near his foot twice. Rinse and repeat. If Player 1 hits mutated Tetsuo, the mutation animation plays in reverse and he returns to normal. Another attack will set the animation off again, however.
* This is the only level to have actual sound effects in place.
* Pressing too many buttons at once can still crash the game.
* Pressing '''Start''' will not go back to the level select, but instead plays a cutscene of Neo-Tokyo exploding with a sound effect. Afterwards, the game goes back to the Sega screen.<ref>https://twitter.com/_gf64/status/1257884266853261312 _gf64] (Cheat code)</ref>

* '''Up''': Stand up, enter background layer, climb up ladder.
* '''A''': Shoot gun/Punch.
* '''A + Down''': Block
* '''B''': Jump
* '''C''': Kick

* The first of two platforming stages. In these, you control Kaneda in a very side-scroller fashion. He can jump, climb ladders, kick and shoot a gun. Shooting the gun drains your ammo, which you can refill with items. Once you're out of ammo, your gun gets replaced with a punch and the ability to block.
* There's also an interesting mechanic in this level: the ability to switch between the background and foreground layers through door-like holes on the wall.
* No music plays in this level.
* Pill: Restores your Str. (health)
* Uzi: Restores your ammo.

'''Army Hospital #2 - Level 3(T)'''

* The second first-person level. Very similar to the first one, but with a few noticeable differences.
* There are no enemies present in the stage.
* The area/room labels aren't present.
* The bear seen in the movie's hallucination scene can be found and fought in the central room. Once the bear is killed, Takashi appears and vanishes.

'''Flight to Fate - Level 3(K)'''

* A side-scrolling bike-escape maze sequence with a rather impressive pseudo-3D effect. This is one of the few levels to actually have sound effects: a sound for shooting, a sound for bullets hitting metal, an explosion sound and a "NO!" soundclip for the enemies. Shooting the bike gun drains your ammo.

'''Olympic Bridge - Level 4(T)'''

* This one is an isometric stage starri
ng a freshly broken-out Tetsuo. All he can do is move around and shoot out Esper energy waves. However, he can charge up those energy waves to make them even deadlier.
* This stage suffers from tile scrolling bugs.
* Both this stage and Level 4(K) share the same music, which is different from Level 2(T) and Level 3(T).

'''Platform Action - Level 4(K)'''

* The second of two platforming stages. Takes place on the famous elevator.
* Erroneously shares the same cutscene as Level 3(K).
* This stage suffers from tile scrolling bugs like Level 4(T).

'''Psychic Stormwall - Level 5(K)'''

'''Player 1 (Kaneda)''':

* '''Left/Right''': Move left/right.
* '''Down''': Crouch
* '''Left/Right + Down''': Crouch to left/right.
* '''Up''': Jumping (can cause the game to freeze if let go).
* '''A''': Punch
* '''B''': Block
* '''C''': Kick
* '''C + Up''': Jump kick.
* '''C + Down''': Crouch kick.

'''Player 2 (Tetsuo)''':

* '''Left/Right''': Move left/right.
* '''Down''': Crouch
* '''Left/Right + Down''': Crouch to left/right.
* '''Up''': Jumping (doesn't cause the game to freeze like Kaneda).
* '''A''': Punch
* '''B''': Block
* '''C''': Kick
* '''C + Up''': Jump kick.
* '''C + Down''': Crouch kick.

* This level was meant to be the climactic showdown between Tetsuo and Kaneda from the movie. However, you can't really do much here, because the game freezes upon loading into the fifth stage. This can be fixed with Action Replay code 00D5F4:4E71.
* In terms of gameplay, this level is similar to the platformer levels, but with one boss instead of multiple enemies. Players 1 and 2 take control as Kaneda and Tetsuo, respectively, and pummel each other until one loses enough health. Tetsuo mutates once this happens, while Kaneda stops getting staggered by attacks.
* Once Tetsuo mutates, Player 2 is unable to control him, and starts cycling through a set of actions. He walks forwards then backwards, jumps in place twice, attacks with a flesh whip from his hand twice, spits slime at Kaneda, and uses a similar whip near his foot twice. Rinse and repeat. If Player 1 hits mutated Tetsuo, the mutation animation plays in reverse and he returns to normal. Another attack will set the animation off again, however.
* This is the only level to have actual sound effects in place.
* Pressing too many buttons at once can still crash the game.
* Pressing '''Start''' will not go back to the level select, but instead plays a cutscene of Neo-Tokyo exploding with a sound effect. Afterwards, the game goes back to the Sega screen.<ref>https://twitter.com/_gf64/status/1257884266853261312 _gf64] (Cheat code)</ref>

A prototype of Dragon Warrior II for the NES.
==Notes==
* Early English localization prototype.
* No pre-title copyright screen.
* Different title screen, matching neither the Japanese nor the US final builds.
* Game is referred to as "DRAGON WARRIOR II", rather than "DRAGON WARRIOR PART2".
* No scrolling prologue as in the US final. This is instead presented to the player using text boxes.
* Text is often different - most frequently in its use of punctuation, capital letters and spacing. Some sections of text were rewritten entirely, and grammar is sometimes bad.

Galaga (1983 Atari prototype)

}}
Unreleased port of Galaga developed as part of an aborted 1983 deal where Atari would distribute the Famicom outside Japan.
==Notes==
- Atari contracted Nintendo to develop ports of 4 titles that Atari owned the home rights to (Galaga, Joust, Millipede, and Stargate) as launch titles for Atari's version of the Famicom. Nintendo then subcontracted development on these titles to HAL Laboratory. After the deal fell through, HAL eventually released Joust, Millipede, and Stargate themselves, but Galaga never saw a release as Namco had already put out their own Famicom port of Galaga. Namco's port is entirely different from HAL's port.

- The CHR ROM to this prototype is lost, and had to be recreated to make the game fully playable. The graphics were sourced from HAL's other arcade ports and from the arcade version of Galaga. The download on this release page includes both a .nes file with the recreated CHR ROM, and the standalone original PRG ROM file.

An incomplete prototype of '''''Magical Puzzle Popils''''' for the Famicom.
==Notes==
{{Tcrf link|Magical Puzzle Popils (NES)}}
* Because PRG 0 is missing, this ROM contains no audio whatsoever, but miraculously, the rest of the game appears to be present.
* Included are the individual EPROM dumps, as well as a ROM file that's been rigged to run on most emulators by padding out the first 32kb of the rom.
* Developed and was to be published by Tengen, was also ported to the Game Gear and PC Engine as well, but only the Game Gear port ever saw the light of day.

==Notes==
* A cancelled game which was eventually reformulated into the Maxivision 15-in-1. According to the producer, it had to be paired down due to "licensing and manufacturing issues. We didnt have the rights to all the stuff when we did the infomercial", with another factor being that "it was also cheaper to manufacture a cart with half the memory".
* Wally Bear and the NO! Gang, called Wally Bear here, is a prototype.
* Dudes II is a placeholder and redirects the player to Chiller.
