Q1: When you tried those different versions of chain.c32, have you 
also used the corresponding version of ISOLINUX? Or you only changed 
chain.c32 versions?

Q2: When testing chain.c32 from Syslinux 5.00 and booting with 
isolinux.bin from the same version, have you also used (at least) 
ldlinux.c32, libutil_com.c32 and libcom32.c32 (or ldlinux.c32 + all 
lib*.c32 files)?
