Doesn't work. There is an LE signature but it's not at offset 0x3C in the BW header:

1C:\DOS\CR\CART. EXE
2File size is 1247899
3Exec 1
4Signature: MZ
5startVal as char
6HeaderVal[0x18] : 0000001E, start val[0x3C]: 09B40000
7Exec 2 is BW
8HeaderVal[0x18] : 08183FFF, start val[0x3C]: 00009200
9LE Signature missing

The LE signature occurs after a bunch of DOS4GW string later on.

[EDIT] I think I messed up the code translation.
[EDIT2] Nope, the exe defies analysis.

Let's try more details.
In order to replace DOS/4GW from Indycar Racing 2 with Dos32A, first manually unbind the linear executable.
That means, make a copy of the original executable and remove first 0x28C9C (167068) bytes from the copy. The new file should begin with LE header.
Then bind Dos32A to the new file using "sb /b" or "sb /bs".

OK that makes sense.

That worked! Thanks!
