I honestly think people should stop being so obsessed with the glitch and try playing the game the way it was intended.
I've made it to Pandemonium now and the only time I even used a glitch was to level up the Heal spell quicker, and only because I couldn't find any good reason to use it and needed it at LV5 since I was about to enter the Whirlwind (where you constantly get turned to Stone).
I never used a single Save State either, the game is definitely beat-able without the glitch if you know what you're doing.

Trust me, the game is so much more fun when you feel that your stats raise naturally.
If you have problems with a dungeon, just exit, rest and re-enter, and do it until you are strong enough to make it to the boss.

I will submit a glitch-free guide for this game on Gamefaqs soon, where I will give advice on good leveling spots and strategies instead of mentioning the glitch (and the cheap Blood Sword strategy, for that matter) everywhere (because I'm honestly really tired of those kinds of guides, it's like getting the advice to use Knights of Round on Sephiroth).
