I tried using the information you entered, but the patch file is not recognized.
The work was done as follows, so if there are any mistakes, I would appreciate it if you could explain them.
1. Download the popnhax-main zip file and unzip it to the pop'n music installation path.
2. Enter the popnhax folder in the dist folder within the popnhax-main folder and rename the ifs_hook.dll file to popnhax.dll file.
3. Edit the patch details of the popnhax.xml file in the same folder using notepad2.
4. Move the popnhax.dll file and popnhax.xml file from the popnhax-main folder to the contents folder.
5. Run spicecfg.exe and change the inject hook path in the options tab to popnhax.dll.
6.Run spice.exe.
After going through this process, popnhax.dll was recognized, but the patch application did not proceed properly, so I would be grateful if you could tell me the exact solution.
