In our example, there is a matching pattern in memory, starting at the 11th number “0”, ending at the 16th number “1”. If the target value is, say, “010101”, and the virtual memory address space is like “00000111110101010110011000…”, locating our target value in virtual memory address space is as easy as searching for a string pattern inside a paragraph. That’s to say, both data and instructions are translated to a combination of 0s and 1s ultimately, and a process’ virtual memory address space is filled with 0s and 1s. Humans can’t read machine code, but machines can - it’s their native language! And all machine code is binary format, it’s a mix of 0s and 1s. I bet you know that, however deep level code we write, it’s human-readable. But where’s the target value address? How do we locate it? Keep reading. But how? There’re addresses in memory, we can simply locate the address where our target value resides, and use system APIs to read/write it. Think with me: What’s a memory editor? Sure it edits memory. So now let’s try to turn the above theory into a programming model, hence we can write code to realize our thoughts. So the above concepts can be depicted by the following scrawls:Īfter a brief introduction to the basic concepts, you may wonder, what does that have to do with our goal? Good question. Each memory region contains a number of virtual memory pages, and pay attention, memory regions may not be contiguous. The virtual memory address space of a process consists of numerous regions of memory. The actual size of memory a process uses is called the process’ virtual memory address space, and the 4GB virtual memory space is divided into many many memory pages for distribution, while memory page is “a fixed-length (4096 bytes on iOS/OSX) contiguous block of virtual memory, and it is the smallest unit of data for memory operation”. But most processes don’t take 4GB memory to run, they consume only a small part of 4GB. Most of the memory operations we do are based on virtual memory, and for a 32-bit processor like ARMv7, the virtual memory size for each process is 2^32 = 4G bytes large. process A and B run in different memory areas), and this is achieved by memory virtualization. Where in memory is this process located? This is a very complicated procedure that ATM, the only thing you need to know is that every process has its own separate memory space (i.e. When OS runs an executable, it loads this executable from hard disk to memory. Virtual memory, memory page and memory region So bare in mind, process contains data and instructions, and they’re in memory. Executable is stored on hard disk, while process is “stored” in memory. We can view executable as static, process as dynamic. So actually executable and process are different status of a same object, i.e. When the executable is run by OS, it becomes a process. On iOS/OSX, executables are all MachO format, containing data and instructions needed for execution. We write HelloWorld.c, compile it and get HelloWorld.exe, an executable. Feel free to correct me if anything is wrong, and have fun Part I Basic concepts 1. ![]() Our target is a working memory editor (game trainer) who successfully cheats “ Blood & Glory 2” from OSX App Store and “ 大富翁4FunLite” from iOS App Store. Today I’ll be here guiding you through the very basic knowledge of writing a memory editor, we’ll review some basic concepts which may be ignored by Objective-C coders, describe how a memory editor works, explain the usage of some memory manipulation functions, and write the code at last. Memory editor is used as game trainer on iOS/OSX by most power users, but very few App Store developers know how to write one. ![]() The game has improved in a lot ways since the first part by offering more fights, movements, characters and blood.Please include the above name and link with repost, thank you. Even though they are not normal rivals in the arena, they are ferocious fighters.īlood and Glory: Legend is a seriously fun action game with awesome graphics. In addition to normal gladiators, with different weapons and armor, you can find some special warriors like giants or women. Throughout the different tournaments that you can participate in, you will have to face numerous enemies. You have to know exactly when to duck, when to block your enemy's attack, and of course, how to launch your own attack. The combat system, just like in Infinity Blade, is based exclusively on your ability to perfectly time your moves. In this game, the players have to take on other gladiators in a Roman arena to fight for prestige, glory and gold. Blood and Glory: Legend, the continuation of the awesome Blood and Glory series, is a fighting game, like Infinity Blade, for Android. ![]()
