Revisional Differences

Elementary, my dear Cactus.
This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: What is different between the unique hardware revisions?

Tetris Plus 2 was released for two different arcade platforms. An earlier revision was created for Jaleco's cartridge-based MegaSystem 32 arcade system, and the later version was released on a unique platform. The likely reason for this is cost reduction, as the newer board replaces the V70 and Z80 CPUs with a single 68000 and has fewer custom chips.

Music

  • The MegaSystem 32 revision uses sequenced music, while the unique hardware revisions use prerecorded audio streams, which are also differently arranged. Certain audio gimmicks such as the increasing speed in the Endless Mode background music have been removed as a result.

Graphics

The newer hardware is inferior graphic-wise compared to the MegaSystem 32, not supporting effects such as scaling, transparency and rotation. Some tweaks were done to accommodate this hardware change, and are noticeable in the game's title screen, how to play screen, and in gameplay.

Title Screen

  • The beginning of the Assistant's section in the Intro was cut down; the animation now starts when she's halfway through the screen.
  • The title logo instantly appears on the top half of the screen before bouncing a little, instead of appearing from above it like in the MegaSystem 32 revision.

How To Play

  • There is no transparency in the playfield; this is also true for the Endless Mode gameplay.
  • The upcoming Tetrimino blocks are no longer scaled down.
  • The English text spacing is a little wider.

Puzzle Mode Gameplay

Endless Mode Intro

  • The obscured background picture no longer zooms to the screen.
  • The "START" text no longer gives the impression of bouncing when moving upwards.

Endless Mode Gameplay

  • There is no palette cycling in the obscured areas of the background picture.
  • The bars on the sides of the playfield are always full. As such, the only way to determine when a level up will occur is via the flashing lights above them.

Endless Mode Stage Clear

  • The "Chapter Clear" and "Bonus" graphics no longer zoom to the screen, leaving a rather... sloppy animation.
  • The "Level Down" graphic no longer moves upward.
  • The revealed background picture no longer moves to the left after the level amount is decreased.
  • The playfield suddenly appears on-screen instead of appearing from outside of it.
