Chankast alpha 025

I'm not sure if I'm allowed to post this since it doesn't have anything to do with the wii. Anyway I got Chankast off the net for my games, mainly the Sonic Adventure games, and I was wondering how to fix the graphics problem of the floor disappearing. It happens on every game except the fighting ones (Marvel vs. Capcom series, Soul Calibur, Jet Grind Radio). Also Toy Commander just refuses to boot. I have:

Dell Dimension DIM3000
Intel Pentium 4 CPU 2.80 GHz, 2.79 GHz,
2.79 GHz,1.50GB of RAM
======================
that's wat it says if u right-click My Computer and hit properties
================================================
Microsoft Windows XP
Home Edition
Version 2002
Service Pack 3
=====================
same as above
======================
Intel 82865G Graphics controller
Total Memory: 96MB
BIOS: Phoneix ROM BIOS PLUS version 1.10 A02
=======================================
this is wat I get if I run the dxdiag program and if I hit the display tab
================================================
but for memory on the system tab it says this
======================================
Memory: 1534MB RAM
====================
Which one is right in my problem? And how do I fix the graphics?


Note: I copied this verbatim. If it's wrong blame my pc!

Why don't you just play the games on a dreamcast?

Cuz it's in mint condition in the original box with the games also in mint condition. I plan to eventually sell it on eBay for a lot of moolah even though I really don't like SEGA. Now would you please help me with my problem?

You could try a different emulator such as NullDC. I have a dreamcast so I've never been interested in its emulation.

I tried that already. Null DC is even worse! Any other suggestions though?
