Hi,
Thank you for helping. Okay:
1. I tried e c316:903a 75, and I see the je changed to jne. However, the
app continues to hang inside that loop...
2. I tried e c316:903a EB08, and I see the je changed to or [bi+si], cl .
The app continues to hang inside that loop. However, I think I am not doing
exactly what Ryan wanted me to do though...
3. I tried d si+0x8 10 after the test statement. The value does not
change. I checked it for 4 iterations.
What else can I try?
