Sonic Advance 3 (Apr 28, 2004 Japanese kiosk demo)

A Japanese kiosk demo of Sonic Advance 3 for Game Boy Advance.
==Notes==
* The demo allows the player to play any of the first four Zones of the game, and all characters are immediately available from the beginning. 
* Clearing the Boss Act of Toy Kingdom will not advance the player to Twinkle Snow, but will instead redirect them back to Route 99. 
* An invisible time limit of 10 minutes is imposed on gameplay - when time is up, gameplay is halted with a message, then the game resets.
* Only the main game in single-player mode is available - all other menu choices are inaccessible. 
* This also prevents the user from changing the language, thus the demo is only playable in Japanese.
Sonic Advance 3 (Mar 1, 2004 prototype)

A prototype of Sonic Advance 3 for the Nintendo Game Boy Advance.
==Notes==
*This prototype was leaked by a German magazine employee in March 2004, well ahead of the final game's June release, leading to quite a bit of drama at Sega and beyond.
*The prototype is nearly complete; almost all of the changes made from here were bug fixes.

Sonic Adventure Taikenban (Mar 2, 1999 build)

A short playable demo made exclusively for Japan of Sonic Adventure for the Sega Dreamcast.
==Notes==
* Made a few months after the initial Japanese release.
* The build seems to be loosely based on the initial Japanese release as it still contains all the files used in the original with slight alterations.
* This build seems to have been made around the time when work on the International versions had just started.
* The build contains level layout and other aesthetic changes to make the game overall much easier than the final (for instance, Chaos 0 dies in one hit, stage hazards in Emerald Coast have been removed, etc).
* As Sonic, the game ends after the conclusion of the first Eggman boss battle.

Sonic Adventure Tournament Disk (Aug 10, 1999 prototype)

A prototype of the Sonic Adventure Tournament Disc for the Sega Dreamcast.
==Notes==
This prototype is documented on TCRF and SEGA Dreamcast Info.
* Used on the Sega Dreamcast Mobile Assault Tour.
* Almost identical to the released Sonic Adventure, except for a few minor differences.
** Different track used on the title screen.
** Post title screen demos don't exist.
** ADX files have not been down sampled to 32khz yet.
** Some ADX files are missing that were present in both Japanese and US releases.
** Game boots right to Emerald Coast as Sonic with all of his unlockable abilities.
** You have 2 minutes to clear Emerald Coast, with a small timer appearing before time runs out.
** When time runs out or when you clear the stage, the score board stays in place before you press START.
** Some German/French localization files are a little different.
** The disc contains the same extras as the Japanese final disc.
** TGS_SOUSA_x.PRS files are present which were removed from the US final.

Sonic Heroes (NPDP Prototype 2)

==Notes==
* This appears to be a near final build.
* This build is more recent than the October 8, 2003 prototype but older than the November 18, 2003 prototype.
===General Changes===
*Basic debug mode (L+R in-game) is still enabled.
*The text on the Blue Window doesn't have the drop shadow added.
*The main menu background (RW Maestro) often does not successfully render after returning from gameplay until switching to another menu.
*This build can crash on Seaside Hill (maybe other stages too?) due to an unknown memory issue. First symptom is usually the ADX Decoder (Music) looping.
*The story mode progression counter has been implemented but is broken. Displays -03 after completion of any map.
*Omochao somewhat works (unlike Oct 8 prototype) but only has speech (no text), locks controls and disappears quickly.
*Super Hard Mode cannot be enabled without hacking. Layout data for Super Hard not present on ROM.
*Unlike Oct 8, Prototype, most menus can be navigated in any order (left-right-up-down) instead of just a fixed order.
*Egg Emperor has a more recent model; complete with the Eggman texture for the cockpit (Oct 8, Prototype just has a spinny circle); but is not quite the final (music still missing). His gameplay resembles the final build (unlike Oct 8, Prototype).
*Some early stages for Team Rose have been shortened down since the Oct 8, Prototype (e.g. Ocean Palace), while others remain longer (e.g. Power Plant).
*Characters in the selection screen have slightly different positioning.
*Rouge's eyelids (a separate model) are not rendered in the menu screens.
*The sound test and CG theater are still fully unlocked.
*The player starts off with 119 emblems.

Sonic Mega Collection (Aug 15, 2002 prototype)

A prototype of Sonic Mega Collection for the Nintendo GameCube.
==Notes==
*The build contains leftovers for Choro Q on the disc for some reason.
*This build contains leftovers for Sonic CD, but it doesn't physically exist on the disc.
*The ROM used for Sonic Spinball is a scene release of a very late prototype, with the Sonic 1/2 main theme on the title screen. In the final, this was changed to use the final ROM with the original theme by Howard Drossin.
*This prototype contains two copies of Blue Spheres (Sonic & Knuckles + Sonic 1), "knu_p1_us" and "knu_p1". "knu_p1" is used in this version and is also byte for byte identical to what is used in the retail version. "knu_p1_us" however is a copy of the ROM that contains a XOR'd message in the memo section of the header that writes "SEGA CHANNEL".
*Sonic the Hedgehog 2 in this version uses a ROM that's byte for byte identical to what is used in the original REV01 release of the game. However, the retail version of Sonic Mega Collection uses a new REV01 ROM where the only differences are a recalculated checksum and a single byte change at 0x9795 (0x3F was changed to 0xBF in Sonic Mega Collection). This changes a piece of code at 0x9792 from "move.b #$3F,d0" to "move.b #$BF,d0". This seems to affect a bug where Oil Ocean Zone's music can still play even when the game has returned from the level select screen after inputting a certain cheat.

Sonic Mega Collection (Sega of America recording)

A Sega of America tester's recording of Sonic Mega Collection for Nintendo GameCube. Sonic CulT founder Pachuka may have had access to this tape during his days at Sega as a "QA Jockey" in the early 2000s. 
==Notes==
*This prototype appears to be even earlier than the August 15th build present on the wiki.
*The title screen uses Sonic CD's (Japanese/European) music as a placeholder.
*The main menu is just a placeholder, with the only functional option being "Games".
