Download Knuckles in Sonic 1 ROM Hack

                 Knuckles the Echidna in Sonic the Hedgehog Rev 01

This is a modification of Sonic 1 to allow play as Knuckles. It was created using 
Hivebrain's Sonic 1 disassembly, and my own Sonic and Knuckles "upmem" disassembly.
It not only contains a fully playable Knuckles, but also a new title screen, new
demos, Knuckles in the continue and ending sequences, and Knuckles equivalants
of all other sprites that refer to the character's identity. Testing on actual
hardware was conducted by LocalH

Data Modifications and Tools/Credits:

-SonED2 used to trace over life icon, level sign, continue icon, title logo art,
 and large ending sequence sprite to make suitable for S1 Sonic palette
-Patcher program made to patch Knuckles art data to use S1 Sonic palette, with
 manually-created table
-Mappings conversion program made to convert S2K mappings to S1 format
-"Knuckles the Echidna In" for ending manually drawn and converted to tiles by
 SonED2
-New frames for Knuckles in ending made by Liz, converted to tiles by SonED2
-Mappings for "Knuckles Has Passed" and new ending sprites created with Lost
 Library
-Some levels slightly modified to prevent impasses and errors that wouldn't
 "realistically" happen, using SonED2
-New demos created with info from drx on the built-in demo recorder, and a demo
 playback bugfix created by me
