![]() ![]() The already explained things above is actually what the mod loader, that has been going around, is doing. How does Skyth’s PD Loader work? Does his mod make the game believe all the other mods in the “mod” folder is dlc? The above language is called assembly and is what every computer basically uses to execute anything. The byte sequence above translates to: movzx eax, BYTE PTR load song played statusĪnd is replaced with: mov al, 1 1 equals yes/true here (song played = yes) exe file there is a sequence 0F B6 81 1D 01 00 00 C3 (hexadecimal obviously), replacing this with B0 01 C3 90 90 90 90 90 will basically fool the game into always saying This song has been played before making the extreme version show up. This is called reverse engineering and is one of my major passions I went into IT for.Īs a small example (The extreme unlock patch): The art is figuring out what byte in the program does what and how you can change the instructions of the program to do things differently. ![]() exe file before loaded or in your RAM) will lead to the CPU doing things differently. When a program starts, those bytes get loaded into your RAM. In the end programs are just bytes written to a file that have specific meaning to the CPU. This might be a little advanced, especially when you have no software development background at all, but the gist of it is: how do you change the executing memory/file? The correct order is not important to illustrate but it shows that everything under (Game installation directory)/rom_steam_dlc gets loaded by the game if required. Is the file in rom_ps4/2d/aet_game_cmn.bin?.Is the file in rom_ps4_dlc/2d/aet_game_cmn.bin?.Is the file in rom_ps4_fix_en/2d/aet_game_cmn.bin?.Is the file in rom_ps4_patch/2d/aet_game_cmn.bin?.On PS4 for example the order was something like this: Assume the game wants to load 2d/aet_game_cmn.bin. cpk files, but the game will only load a file from there when there's no file with a higher priority. How do you replace files? Do you have to extract cpk and package it again as cpk after you replace the file? How do you make them believe they are dlc Basically anything that would allow you to edit the game while it is running. I was hinting at hex editors, programs you might have to write yourself (using the Windows API), 圆4dbg, etc. The others are mostly editors and programs for extracting/packaging. VSCode is an IDE as far as I'm aware (for writing code). Vscode, mmd, cpk extractor, farc extractor and such? ![]()
