WOW!! I think I've finally got a working cracked STEEL.EXE. I figured out there are four locations to modify. Two of these are checksums. Replacing these with NOPs seems to fix it. Now no message about "CRC failure" comes up. The other modification was made so that savegames are no longer checked and corrupted if CRC mismatch occurs. To crack the game, perform the following modifcations to the STEEL.EXE file at these offsets. The file should be exactly 759,404 bytes:
0x0464A0: 74 06 FF 46 B6 E9 05 00
to: 90 90 90 90 90 90 90 90
0x069B30: 75 09
to: 90 90
0x069EA0: 75 09
to 90 90
0x06F710: 7E 03
to 90 90
It is now cracked! Test this out to make sure I haven't missed anything. Hopefully the game should now be able to be completed normally.
