The XCFN consists of three resources; XFCN "StandardFile", DITL "GetDir" -3969, and DLOG "GetDir" -3969. All three must be in your stack for StandardFile() to work. The DLOG/DITL are accessed by NUMBER and so their ids must not be changed (-3969 suggests it is owned by the standard file package…). The XFCN is written in Think C 3.0 with asm{} statements to decrease code size (I only have 1M so I try to make all my XFCN/XCMDs as small as possible!).
