Tengen Tetris (Prototype B)

A prototype of Tengen Tetris for the NES.
==Notes==
* Has a different and more basic-looking intro screen, with a more basic logo. The menu music is different, using a theme that was never heard in the final game.
** There are no fireworks on this screen, in this version.
** In the copyright text, "(C)1987 ACADEMYSOFT-ELORG." begins with a "TM", in this version.
** The copyright text also shows "(C)1988 TENGEN." instead of "(C)1988 TENGEN".
* The screen border is visually very different, and is green and red instead of blue.
* The main menu has a different logo to the one used in the final, notably including "TENGEN PRESENTS" above it.
** The differences in the Tetris logo also carry into the gameplay HUD.
* The autodemo is not properly recorded yet, so the demo places all the blocks to the left of the screen, quickly resulting in a game over.
** The main menu music continues into the autodemo rather than the demo being silent.
* The only options on the main menu are "1 PLAYER" and "2 PLAYER" - there are no cooperative or versus computer modes.
* The menus - aside from the title screen - are missing their licensing info.
* There are no handicap or music menus, and only two tracks (Bradinsky in 1 player mode, Loginska in 2 player mode) play in-game.
* The HUD at the top of the screen in the menus is wider than in the final game.
** Additionally, the rows are "HIGH SCORE", "SCORE" and "LINES", rather than "SCORE", "LINES" and "LEVEL".
* The menu sound effects differ from the final.
* The blocks all have a different look, with each block being represented by a unique pattern. The blocks look much more primitive than they do in the final as they lack defined borders or a 3D design.
** The block stats on the right half of the screen do not feature images of the blocks underneath; instead, they're identified by that respective block's unique pattern.
* The "STATS" text is lower than it is in the final.
* The "HIGH SCORE" is set to 0 by default instead of 17000, and the high score in the HUD is placed a bit differently to how it appears in the final.
* The "PAUSE" text does not have a red border around it, in this version.
* The "GAME OVER" text has a blue border instead of a red one.
* There are no Russian dancers or bonus screen each level increase - instead, the game continues as if nothing important had happened. 
** Also, the level increases every 10 lines, instead of every 30.
* Blocks hold the same colour and pattern when they drop, rather than changing to a different colour like they do in the final.
* The block dropping sound differs from the final.
* Blocks often cannot be turned when they are pressed against the wall.
* There is no high score screen after gameplay.
* Score numbers for individually placed blocks are always white instead of appearing in multiple colours.
* Lines clear instantly without any visual effects.
** Unlike Prototype C, when multiple lines are cleared they all disappear simultaneously, like Prototypes A and D.
** They also do not show text indicating how many lines have been scored ("SINGLE", "DOUBLE", etc).
** The blocks do not clear from left to right as they do in the final, instead all blocks in a row clear simultaneously.
