Wow! Awesome job, broseph!

Wow! That's actually really neat!

I spent four years reverse engineering PSP games, but there weren't nearly as many tools available for that as there are for the PC. I've also spent a couple years of my life studying game design and even writing my own 2D games. So when it comes to reverse engineering, I have a pretty good grasp on how to locate things and modify them to my advantage. Everything I find, I log. This enables me to map the memory and get a good idea for where I can find stuff in the future. For example, I started working on making my bullets explode like RPGs this morning, and I thought the best place to start would be to find the function that determines what type of item to throw, launch or fire. I remembered that, while looking for Rapid Fire, I found a code that made special weapons (flamethrowers, RPGs, spray paints, etc.) fire actual bullets instead of their respective types of "ammo." I started there, and much to my surprise, right above the instruction I modified to achieve that effect was a call to a function pointer. Low and behold the function pointers point to the functions for firing whatever type of ammo you're currently trying to fire. About an hour of tracing and comparing later, I made a cheat to make all weapons fire rockets. It's amazing to use on the jetpack! I'm pretty excited about this one because, theoretically, I can now make any weapon shoot any type of ammo I want. I'm going to try molotovs next! [media=] [/media]As for reverse engineering file formats, I've never been good with decryption. I'm a fan of writing my own algorithms to encrypt data, but I don't know anything about decryption. I don't find it all that interesting either. I'm better with busting open CheatEngine and staring at a game's ASM for hours on end. Don't ask me why. Edit: Got it!

Hey thanks broseph, glad you found it fun. I'm always trying to come up with new ideas with games like these. The possibilities are endless!

So as I promised, here's a video of the rapid fire cheat I was working on. It took me several days of studying the ASM and tracing the origins of the shooting function, but I finally landed it. It isn't perfect, I set it to automatically fire when you hold the right mouse button or press the left mouse button, but it works nonetheless. If anyone knows C++, you can use the code supplied to add it to your trainer, or just modify the instructions in memory with a program like CheatEngine to get it to work. Or, maybe someone will be nice enough to convert it to CLEO since I know nothing about that. The recoil is a little annoying, I'll have to fix that so all bullets go perfectly straight. Enjoy though! [media=] [/media] void enableRapidFire() { WriteProcessMemory(gtaProcess, (LPVOID)rapidFire1, &enableRapidFire1, 2, NULL); WriteProcessMemory(gtaProcess, (LPVOID)rapidFire2, &enableRapidFire2, 2, NULL); } void disableRapidFire() { WriteProcessMemory(gtaProcess, (LPVOID)rapidFire1, &disableRapidFire1, 2, NULL); WriteProcessMemory(gtaProcess, (LPVOID)rapidFire2, &disableRapidFire2, 2, NULL); } Declarations: DWORD rapidFire1 = 0x00624f00; //These are the addresses in memory that you'll want to modify DWORD rapidFire2 = 0x00624F06; BYTE enableRapidFire1[3] = "\x90\x90"; //These are the bytes you'll use to enable rapid fire BYTE enableRapidFire2[3] = "\x75\x0A"; BYTE disableRapidFire1[3] = "\x75\x24"; //These are the bytes you'll use to disable rapid fire BYTE disableRapidFire2[3] = "\x74\x0A";

Ironically, I don't know anything about CLEO. I have it installed on my computer, but no idea what it does. I'm more of a reverse engineering type of guy. If someone wants to convert it to CLEO, that'd be great. I spent the last few days working on a rapid fire too. So I have all the weapons fully rapid. It's neat, I'll post a video soon and maybe someone can convert that one as well.

Haha, it actually does! So if you lock onto a helicopter, you can ride it all the way up to take it out! Unfortunately, I've only memorized the cheat for a specific weapon set that doesn't have the heat seekers. Yeah, I originally made the video to show my brother, but figured I would bust into the scene with it. I showed him a video prior to this one that had the same song and he hated it, so I figured I would use it here.

Hey guys, I recently made a cheat for San Andreas in my off time. It lets you "ride" rockets and molotovs (probably grenades and other thrown items too, I haven't tested it). It's written in ASM and I'm not finished with my trainer, so if you want to use it, you'll have to modify the memory yourself with a program like CheatEngine. Enjoy! BTW, the music is a total inside joke between my brother and I, so please don't take offense.
