I downloaded the X2 4981.06 BIOS & tried it. I wrongly assumed that the X2 Bioses were 512K or 1024K. After rechecking the
Retail BIOS site, I realized that the inflated Bioses are also the ones that have embedded .xbe programs. Is this why they are so large?
Anyway, the IGR now works every time, every game so far. Thanks all for your help.
I am still working on my controller reset function. See my thread:
Reset thread. If the link dies, search for Topic Title "Cold reset from controller."
