It is in the correct format.  Non-EFI boots start in real mode.

'$(NASM) -f elf' in MAKEFILE under ./core/ dir.

It is in the right format especially when you look at the final product.

Depends.  What Windows version across what media?  chain.c32 can boot a
local hard drive.  MEMDISK can boot some ISOs, specifically most PE and
PE-like systems.  iPXE's wimboot is probably the best choice for network
booting if you have an appropriate file.
