Essence [Original Resource] Simple Tutorial for Modifying Games in JAVA

I explored the technique of modifying games on my own, so my skills are not refined—I just know a little. At the request of friends, I am sharing this tutorial. If there are any shortcomings, I hope experienced users will not mind.\ Speaking of modifying games, my experience started with localization. My idea is: since localization is about changing unknowable language into Chinese, doesn't that imply you can change whatever you want? Dialogue, character nicknames, words appearing in the game can all be modified. The following explains the most basic class modifications. Other modifications, such as hexadecimal or image text modifications, are more complex; I only know a bit and will not show off here.\ [Getting to the point]:\ 1. Essential Tools\ Flowing Years, MT (or MC), class editor\ It's best to put these tools in the same folder for convenience. I do not recommend using illegal software, as it can be harmful to your phone.\ 2. Steps to Extract the Game\ Since modifying ‘The Legend of Bodhi Patriarch Prequel' is simple, we will use it as an example.\ Download the game with UC Browser. Don't rush to change the file extension. Create a blank folder. Open MT, click directly on the game to enter it, and you will get some files ending with class. Press the * key to select all. Click the right software option, open the blank folder, and copy all the selected files into the blank folder. Done!\ 3. Modifying the Game Name\ Open the blank folder with the class editor. You will see a folder starting with the letter M. Enter it, and there is another class file inside.\ You can see some text. After 'game name' is the game title. Edit it: delete the original game name, input the desired game name, save, and done! (Note: For stable gameplay, do not arbitrarily delete the spaces before and after the game name.)\ 4. Modifying Game Dialogue, etc.\ Using ‘The Legend of Bodhi Patriarch Prequel' as an example\ Open each class file with the class editor. You can locate the dialogue, NPC conversations, equipment descriptions, etc. Some games even include tips displayed when loading the game or messages indicating charges for text messages.\ Next, it's simple: edit whatever you want to edit, save, and done!\ 5. Modifying Images in the Game\ This is easy: find the image to be replaced, delete it, then save the image you want to replace into that folder. Done!(Note: The image names must be exactly the same!)\ VI. Generating the Game\ After making all the changes, use MT to package the entire folder. Then use 'Liunian' to change the file extension to _jar. After that, exit, and change the file extension from _ to a dot. It should be noted that when renaming files using Liunian, it's best not to use Chinese characters, such as\ Doupo_jar\ This can easily cause software errors.\ It's better to use English or numbers, for example:\ doupo_jar or 123_jar\ After finishing, run the game and see if it works.\ How is it? Fun, right?\ Postscript: The technical knowledge I have in this area is roughly as described above. If you don't understand something, you can ask me, and I will answer as best as I can. To improve proficiency, I suggest trying it with 'Weicheng Wushuang'. Please point out any shortcomings, thank you.
