I've never been able to really play it, or the original version for that matter. Pentagram, if I remember correctly, is supposed to fix the sorcery spells and their 1 pixel perfect grid thing to make it easier to place the reagents. I didn't find this to be true and although I could sometimes get lucky and get it just right, more times than not I would reach this part of the game and get frustrated and quit playing. This was true while using pentagram and while just playing the original game alone. Somehow when I was a kid, I was able to finish the original version of the game and even got the sorcery spells to function properly, but no such luck ever since then.
Really though, apart from the brokenness of trying to prepare sorcery spells, I think the game is completable through pentagram. I don't remember any issues with it. Maybe an occasional crash, but nothing major.
