[Other] Adding Evolution Method Help

[bradmarx]

I am trying to add male and female based evolution using the routine from the thread Adding New Evolution Methods(https://www.pokecommunity.com/showthread.php?t=329357) but I keep getting errors while assembling and cannot figure out why. Also how do I change the .bin file? It says in the thread if I increase the number of evolution I have to change it. Thanks in advance for any help.
