Because the system only supports one range, your slimming code is not in the range. Custom saving will be fat, and it needs to be saved before modifying the source code.

Specific methods: put the slimming code into the corresponding folder, select the code on the game (awkward at this time), and adjust the appearance and color. And save it. Find the folder where you put the code, and change the last paragraph of the newly saved code (after [Body]) to the value in your slimming file. Enter the game and select your saved code. By this time, you have adjusted your appearance and lost weight.

You can leave the game alone in this process.

Note: the code after slimming cannot be adjusted after entering the game. If it is adjusted, it must be saved as a new code and slimmed down manually.
