Retain Rings Between Acts in Sonic 1

(Original guide by Afti)

This is a very simple guide to retaining rings between acts in Sonic 1. It's extremely easy, but, for those who literally have no ASM ability whatsoever...

Well, here it is. You literally need to delete one line, and add one line elsewhere.

In Level_LoadObj, delete this line.

<asm> move.w d0,($FFFFFE20).w ; clear rings</asm>

Then, add this line to KillSonic.

<asm> move.w #0,($FFFFFE20).w ; clear rings</asm>

Place it between these two lines.

<asm> bne.s Kill_NoDeath  ; if yes, branch move.b #0,($FFFFFE2D).w ; remove invincibility</asm>

And... that's all. No example ROM will be provided because it takes all of two minutes to do this.
