Ripping Problem

[p16file]

I'm using teraterm with dreamrip and a serial cable.

Whenever I try to rip a game, it goes extremely slow, about 16k a minute and usually when I get to about 375k, I get weird symbols in the TTerm window. This happens when I'm trying to rip MvC2 and Soul Calibur. However, this doesn't happen when I try to rip Skies of Arcadia.

I've tried using HyperTerminal, defragmenting my disc, and using Rambooster and nothing works.
Can someone help?

Install Rambooster,
set alarm level at 32mb ram,
target level of free ram 64.
CPU usage 28

Restart pc before Ripping,
Turn program like antivirus, getright, msjoystick loader, screen saver off...
Try use dcrip enchance macro to backup gd
Don't try to access internet and use other program while ripping...

I've done all that and I still get errors.
