Single player and multiplayer Tetris

This contains single player and multiplayer Tetris games.

The single player game comes with 4-stage preview tetrominos, hold function, EEPROM-based hiscore and standard Tetris scoring.

The multiplayer game links with a second device over infrared and runs in battle-mode where cleared lines are added to the opponent's board. The display is divided in 2 with the player's screen on the left and the opponent's screen on the right. The winner is the player to survive the longest.

A bodge shield for the incorrect flip-flop pinout

Version v0.1 of the handheld PCB uses an incorrect pinout for the 74LV273's footprint. As a result, the board doesn't work. V0.2 will address this.

This release adds a tiny overlay PCB containing a 74LV273 in SOIC-20 package that goes onto the flip-flop's original footprint and rewires the pinout.

First version sent to JLCPCB

Very basic handheld gaming device based around the ATXMEGA C3 and a custom LED matrix display.
