This program reads symbolic 6502/RP2A03/RP2A07 machine code and compiles (assembles) it into a relocatable object file or into an IPS patch.

The produced object file is binary-compatible with those made with XA65.

This program was born when Bisqwit needed to have something for NES that is already accomplished for SNES by snescom.

This package also contains a linker.

The linker can also be used to convert IPS patches into binary files (an empty space is assumed to be the original file), with the following command:

neslink input.ips -o result.bin -f raw

If you happen to see this program useful for you, I'd appreciate if you tell me :) Perhaps it would motivate me to enhance the program.
