New Galaxian cheats

Post by scott_tunstall » Sun Nov 18, 2018 1:46 pm

Hi,

I've created some cheats for Galaxian if anyone is interested. I've merged my cheats with the current cheat file.

My cheats start @ "Finish Level NOW!" .

These are based off my disassembly work that can be found @ seanriddle.com/galaxian.asm

Regards,
Scott
