these hacks are to add additional features that were edited or cut from the final games and fixes to most
aspects of the games using the SCHGs but at the same time keeping them true to the original games
(No Spin Dash in Sonic 1 and no flight as Tails in Sonic 2).
The hacks can be considered mixes between the later revisions of both games, but these hacks were
created as somewhat of a response to Tiddles' Sonic 3 Complete hack as I wanted to create "complete"
or "fixed" versions of these games with less bugs and more detail.

*In Sonic 1, the beginning of the Green Hill Zone demo doesn't have Sonic moving for five seconds.
*The Labyrinth Zone ripple effect in Sonic 2's CPZ2 and ARZ is said to be obsolete. This could be due to the fact that
the effect will noticeably slow down that act/zone if there are numerous objects on the screen.
*Locking on Sonic & Knuckles with this version of Sonic The Hedgehog 2 will not work as it exceeds
the size of the required rom combination.
