GTA3 Anniversary - Tweaks, Tips, save games etc.

Note this articles is about GTA3 for Android. If you want to play GTA or GTA2 on Android, you should read my other post ;)

I just got 100% completion of Grand Theft Auto III on my stock Rena3 running Android 2.2. I'm starting this topic to help people optimize GTA3 for maximum performance, required for the game to run smoother on Rena3 tablets. Also, I'll help people with tips, if they got stuck somewhere. I've uploaded my 100% completion saves (see below) for curious people wanting to explore all unlocked GTA3 on their mobile device. Ok, here we go...

Tweaks:
Tweak #1: Use GTA3 Graphical Settings + Launcher to reduce drawing distance to minimum (other things should be to low settings already) or download my gta3.set file.
Tweak #2: GTA III Ultra Performance FINAL - This should improve FPS for some quality loss. I had troubles starting the game after installing this mod, but the problem was in handling.cfg file, so backup your com.rockstar.gta3 before applying.
(Maybe) Tweak #3: I've tested RAM Manager Pro, for which the author says "Play GTA 3 and other heavy games without lags.", but didn't found any difference. Still, if you can try it yourself, it may work for you ;)

Tips:
Rule #1: Rocket launcher is your best friend! There are A LOT of missions which can be A LOT easier if you have Rocket launcher.
Rule #2: No cheats if you want 100%
Tip #1: Play the game in reverse - first collect all hidden packages (see Tip #2), do all firetruck, police car and ambulance missions and then go for the missions, as you'll have full arsenal of guns, 6 stars and a heart next to your save place. Also, you'll have an endless sprint, which can be very helpful at times.
Tip #2: To get to second and third islands without cheats, see this video. It could be a bit tricky as you need to go forward, sprint and jump at the same time, which on Rena3 is impossible (2-point multi-touch, and you need 3), but with practice you'll get it when to stop sprinting and jump. After you are in 2nd island, you can get to the 3rd by car - underwater tunnels.
Tip #3: To get the last hidden package (the one that's on the bridge between 2nd and 3rd island) and unlock Rocket launcher, you'll have to learn to fly the Dodo and land on top of the broken bridge. It it's possible, land on your top, to destroy your Dodo, as it'll be much easier to jump to the package.
Tip #4: Use GTA3 100% Completion Checklist to track your progress till 100%.
Tip #5: When doing police car missions, there is a trick to make your target stop and get out of the car - when you are close to him, press back button (to go to menu) and then resume the game. That's it! He'll stop and get out of the car, so you can easily kill him. If it's now working, try again from a longer distance (sometimes it's not working when you are too close).
Tip #6: When doing firetruck mission DON'T turn your water gun. Never! You just go straight ahead and hit the target while pumping water - aim at the engine. This will extinguish the fire immediately.
Tip #7: When you get to do Kenji missions, do them first, I won't tell you why (you'll see) or you won't be able to do 100% completion.
Tip #8: When doing "A Drop in the Ocean" mission, get an FBI car, which you'll need for EV crane. FBI car is the only vehicle not parked anywhere. If you do not get it now, you'll have to reach high wanted level later to get it.
Tip #9: After you complete Ray's missions, use his Patriot to drive around Portland, as it's bulletproof (it's available in my saves below).
Tip #10: Last mission is pretty easy if you have Sniper rifle and Rocket launcher, so after cut scene showing Catalina's chopper, jump down the hill and go to you save place to get you ammunition and then go to the dam and finish the mission - shoot cars and trucks with your RL and columbians with your SR. In the end, shoot down the chopper with RL, go up the stairs, where the columbian snipers were, and shoot all columbians on the roof next to Maria. Now you are ready to meet Maria and finish the game, without a single health lost.

Save games (100% completion):
Portland save - Bulletproof Patriot in the garage
Staunton save - My favorite cars in garage - 2 Cheetahs
Shoreside Vale save - 1 Cheetah and 1 Banshee
Story line save - only story line is completed. The rest is yours ;)
All saves (excluding story line save) here.

I haven't tested GTA3 on 2.3, so if someone is, feel free to share. I've tested the game on 2.3 and it's better. Also make sure to use version 1.3, as it has graphics options in the menu and you can go with even lower resolution for higher FPS. Also I'm open to suggestions as tips and I'll put here most asked questions about missions.
