Forum(?) Need Help Running Sid & Al's IT On Windows XP

I do not know whther this is the right forum, but since this has to deal with some sort of programming. I'll post it in this site.

Okay, I need help running the old classic DOS game, Sid & Al's Incredible Toons.

The problem I get when I have followed almost every step here, is...

Code:

---

You do not have enough memory to run this program.
You currently have 597520 bytes of conventional memory,
and 65536 bytes of EMS memory.
You need at least 57000 bytes of conventional memory,
and 737280 bytes of EMS memory.

---

So I need more EMS memory, how do I do that? The site linked above says to add emm=ram, but that didn't help anything. It also says duel-boot your windows XP to an older version, but I want to be safe (it said it could be harmful?), and I don't even know how to do that.

I use DOSBox and it's perfect

Ok, I'll try it.

EDIT: Ok, it works perfectly, but when I play it, it shows this.
