Hello,
PROTO C in 64 bits need to be changed to fastcall.Here is the better way to proceed.
They are named cproto by the translated sdk,cproto= C in 32,cproto = fastcall in 64
1 step)Change the c prototype in the .sdk for 32 64 bits
Open the file to change with Notepad (math.sdk for example)
use edit-->replace menu
Copy paste those two strings in the box,between the ""
"PROTO C" change to "PROTO cproto"
And clic change all
2 step) add those switch constants in:
cproto equ <fastcall> ;in \sdkrc81\shared\translate64.inc
cproto equ <C> ;in \sdkrc81\shared\sdk32.inc
