One of the most annoying shooters hector. I modded it to take 2 health per hit and 100 or so lives. I'm learning atari 2600 programming but I thought I do another attempt at rom hacking using what I've learned thats better than just changing a couple of values. I did a little test to jump into the middle unused rom so I could put in whatever I want and it actually worked so I should be able to change a lot more in the future. Using fcex debug version actually on linux using wine. It lets you just type in the assembly instructions right into the middle the code, pretty convenient.
I spent days trying to get anywhere in this game so I feel its enough justification to allow me to cheat, it still pretty hard but I intended to make it the same difficulty as gradius. I will do more hacks once I get the hang of in indirect addressing on 6502, I find it a bit confusing really.
