[SOLVED] Sonic MegaMix doesn't work with my SegaCD. Anyone know why?

There is a FANTASTIC hack (or so I hear) of Sonic 1 released for SegaCD entitled Sonic 1 MegaMix. My friend, who introduced me to it, swears by it. She said just burn it to a CD (comes as an .iso) and play. I was stoked.

Upon burning it at 2x and popping it in, I get the SEGA screen, the disclaimer screen, then a silhouette of the Sonic Retro (ソニックレトロ） screen as it fades in, then a freeze. I find this quite odd, since my burned copy of Snatcher runs beautifully after a crazy manual linux command-line conversion and a manual .toc file creation; all of these things would tell me that one shouldn't work, yet it does, and the simple MegaMix .iso doens't. My "real" Sonic CD runs fine too.

She let me borrow her CD, which she had used on her console; hers froze at the same place on my console, but had worked fine on hers. Any clue as to how I can fix this?

I'm running a Model 2 Genesis and a Model 2 SegaCD, software version 2.00.
