Simplify the code by directly using the arguments on the stack as base pointer relative memory references, instead of loading them into intermediate registers first. Make it more robust by preserving all callee saved registers mandated by the C calling convention (and only those), namely EBP, EBX, ESI and EDI. Don't assume anything about the register state when the called function returns -- beside the segment registers and the stack pointer to be still the same as before the call.
