My favorite GTA San Andreas cheat would be flying cars also with unlimited nos, since GTA map was pretty big I always used the cheat to help me get to either just a destination, to a mission or just get a away from a 6 star wanted rating, just cops in general. Also, the jetpack too, it was fun to use the jet-pack for gang territories using 2 upgrade tec-9s, even if i get killed in the jet-pack, I've always use health cheats to stay alive before I land the ground.
My favorite cheats were definetly aezakmi - for the cops to be gone and stop chasing me when I was killing people, hesoyam - because I needed this cheat that gives you health and armor a lot when I was crousing around the city and of course rocketman - because I really liked to fly around with a jatpack.
It's stupid, but I used to love using the "jetpack" cheat and just fly around the Los Santos area. It was amusing and I had some fun and funny moments with it. Ah, good times. On PS2, it was L1, L2, R1, R2, up, down, left, right twice.
HESOYAM and PROFESSIONALSKIT for me. Whenever I get busted or wasted, these two cheats, these are the first cheats I use. Third cheat will be the avoiding cops, TURNDOWNTHEHEAT.
I never used cheats ever for GTA SA I just beat the game with not cheats which is always honorable to do. I would use cheats after I beat the main single player.
My favorite cheat was infinite health and weapons and money cheat. That made most missions easy, especially ones which involved shooting gangs or, if a massive shootout occurred and had to take on everyone at same time. I never used the oxygen cheat as I didn't need it much, had to train though when I had to fight ryder which was bad.
I would mostly use the unlimited health cheat on certain missions where it would be too hard but I finished the game without cheating many times after the first
I am mostly using unlimited health and armor cheat when I use them. I addition, flying cars is useful in performing insane stunts.
I love flying cars cheat and Jetpack. It's pretty fun and also convenient if your destination is pretty far.
I didn't like that much using cheats to this game, but I did use the cheat where your car could run on water to not get caught by cops. But the choppers would have eventually got to me, anyway.
