Hack description

This patch is a gameplay overhaul for Sonic The Hedgehog 2 which not only overhauls
how to obtain Chaos Emeralds but gives each emerald unique abilities that stack.

A simple save function has also been implemented.

How it Works:
In addition to special stages, players can earn emeralds by gaining a continue at the end of each act.
Each emerald will give the player new abilities before obtaining Super Sonic form.

These abilities are as follows:
- First Emerald
Player 1 Gets one extra hit point per life before losing rings. (Does not stack with shields)
- Second Emerald
Player 1 can stay underwater for extremely long periods of time.
- Third Emerald
Player 1 now has faster acceleration.
- Fourth Emerald
Player 1 now earns double rings in normal stages.
- Fifth Emerald
Player 1 now earns double rings in both normal and special stages.
- Sixth Emerald
Player 1 can now jump higher.
- Seventh Emerald
Super Sonic now available.

NOTE:
While Tails cannot obtain Super Form as Player 1, he can gain the emerald abilities listed above.
Super Sonic form now requires 100 rings in order to activate.

SRAM:
Saving:
Game saves at each title card screen transition.

Loading:
Enter the options menu, highlight player select and press start. Highlighting any other option will exit the options screen.

Game Saves:
Current Level and Act
Current Emerald Count
Selected Players (Sonic and/or Tails)

NOTE:
*Game will restart if no prior game save is detected. This is intentional as a checksum system in place.

Patching instructions can be found in the readme.

I like Sonic 2 just as much as the next guy, but man, those special stages were the worst. Cool technical showpieces for the hardware, sure, especially all the way back in 1992, but from a gameplay standpoint? ugh, hated them. The only recreation of the special stage that I did like was in Sonic 4, part 2... about the only thing that worked in that misguided duology. Anyway, what does this wonderful hack do? It streamlines the process of getting the fabled Chaos Emeralds tremendously by tying them to in-zone gameplay performance, rather than breaking the speedy flow of the game for an isolated special stage romp. Not only that, but you get gradual powerups for each emerald, giving the game a cool sense of progression and achievement that was never pursued in the series quite like this, and is a welcome change. I hope the author does something like this for Sonic 3 and Knuckles too! (If you do, please, please make it compatible with Sonic 3 Complete!).
