Street Fighter II: Champion Edition (Jul 30, 1993 prototype)

A prototype of the unreleased Street Fighter II: Champion Edition port for the Sega Mega Drive.
==Notes==
*In comparison to the Turbo bootleg, which was based on a later prototype of the Champion Edition, this prototype contains the following differences:
**The ROM header specifies a date of 1993.JUN, which was Champion Edition's original projected release date, while the Turbo bootleg says 1990.JUL. The ROM header says "STREET FIGHTER II: CHAMPION EDITION" in this prototype. In the bootleg it says "ARM WRESTLING", which is most likely a placeholder caused by a ROM authoring tool. The prototype has a product code and serial of T-12016,0.0 with a calculated checksum while the Turbo ROM lacks a specific entry for both. Oddly enough, this is the same product code and serial that was used for the Special Champion Edition.
**Contains a checksum and region check. The Turbo bootleg lacks the code to perform both.
**Contains a region check to confirm the game is playing on either a NTSC or PAL SECAM console. If the console is set to NTSC-J, the game will boot to a red warning screen. This check isn't present in the Turbo bootleg.
**Boots to a Capcom logo instead of a Sega logo. The ROM lacks any graphics for the Sega logo.
**Different title screen with copyright/trademark information. The Turbo bootleg has its own custom title screen and lacks copyright/trademark information.
**No sound effects play when navigating and selecting anything in the main menu.
**A black bar behind the HUD on the top of the screen. The Turbo bootleg has no such black bar.
**Different alternate costumes for most of the fighters.
**The name of the second fighter is slightly off in comparison to the Turbo bootleg.
**This prototype contains a Street Fighter II logo in the background when navigating the VS mode menu. In the Turbo bootleg, the background is just a solid blue color.
**The player name is the same color as the other text in the VS mode menu in this prototype. In the Turbo bootleg, the player name uses a different palette from the rest of the text.
**The sound test uses a numerical value to represent each track. In the Turbo bootleg, the sound test uses the internal sound IDs instead.
*When using a 3-button controller a feature is enabled in the HUD for indicating whether the player is using punches (red square) or kicks (white circle) that can be swapped pressing Start. This control scheme is similar on all the versions but the released Special Champion Edition lacks any HUD indicator and the Turbo bootleg uses P/K letters instead.
