[QUOTE="ghjfdtg, post: 10056959, member: 351436"] How it usually works: 1. The DS firmware initializes the ROM and encrypted communication. The flashcard pretends to be a game and delivers legit looking data. 2. The firmware reads headers, executables and overlays. The flashcard will at some point deliver modified data/code in form of executables or overlays instead of the game data it pretends to be. Sometimes vulnerabilities are used in the overlay handling of the firmware. 3. The firmware executes the loaded executables and this is where the loader for the "kernel" kicks in. It initializes the microSD card and loads + deobfuscates whatever .dat file the kernel uses from the root of the microSD filesystem. 4. The "kernel" takes over and you will see the menu to select games. 5. If you select a game the "kernel" loads and deobfuscates the ROM loader, passes it some config options and executes it. 6. The ROM loader loads the games executables, overlays and then applies patches so it can read from the microSD via a cluster lookup table. The same is done for savegame read/write. This cluster lookup table is sometimes implemented on the FPGA so the ROM loader just needs to fill it. 7. The game runs. It really is just a big chain of stages of executables. Often just .nds files with or without obfuscation. [/QUOTE]

Only thing drive me crazy is all these new horror games nowadays is its so dark, all time. I can't even play them. I understand they trying to create spooky but be creative a little, not just darkness with pop out scare scenes.
