Tetris: Tetris - Two Player Mod

The two player mod allows two simultaneous players to play while receiving the same pieces. Garbage is not sent between players by default. The GameGenie code KUTPUX or the two player-garbage IPS enables garbage.

There are two variations of the mod. One shows the next piece on the side, which makes it easier to see with peripheral vision. The other shows it on top, which makes it clearer at-a-glance which next piece belongs to which player.

Also included is a handicap mod that provides a height-select for Type A. Instead of Type B's garbage within the height area the area is simply off-limits and unusable.

## How to run

Pre-built IPS mod files are available in the
[releases section of GitHub](https://github.com/ejona86/taus/releases). They
must be applied to the USA Tetris ROM:

```
Database match: Tetris (USA)
Database: No-Intro: Nintendo Entertainment System (v. 20180803-121122)
File SHA-1: 77747840541BFC62A28A5957692A98C550BD6B2B
File CRC32: 6D72C53A
ROM SHA-1: FD9079CB5E8479EB06D93C2AE5175BFCE871746A
ROM CRC32: 1394F57E
```

Or the Europe Tetris ROM:

```
Database match: Tetris (Europe)
Database: No-Intro: Nintendo Entertainment System (v. 20180803-121122)
File SHA-1: 817169B819AADAAE52CCE6B3D8D2FC24270566D7
File CRC32: 8319B091
ROM SHA-1: 66883B9EDDEC933E36B6BFF0479CEFD2434FFB40
ROM CRC32: FDFF80D5
```

You can use [Hasher-js](https://www.romhacking.net/hash/) or [ROM
Hasher](https://www.romhacking.net/utilities/1002/) to verify your ROM matches.
It is generally okay if the "ROM" checksum matches, but the "File" checksum
differs. But note that `make test` will fail.

## Two Player

The twoplayer mod allows two simultaneous players to play while receiving the
same pieces. Garbage is not sent between players by default. The GameGenie code
KUTPUX or the twoplayer-garbage IPS enables garbage.

There are two variations of the mod. One shows the next piece on the side,
which makes it easier to see with peripheral vision. The other shows it on top,
which makes it clearer at-a-glance which next piece belongs to which player.

## Handicap

The handicap mod provides a height-select for Type A. Instead of Type B's
garbage within the height area the area is simply off-limits and unusable.

This mod was originally created as a training aid. When used with the twoplayer
mod it can level the playing field.
