I found a way to fix graphical bugs in this game when using MaldiVes emulator. As you know, the performance in the JoiPlay emulator drops significantly during VN segments and location exploration. While MaldiVes offers much better performance, there are graphical glitches like black bars and other issues that can't be fixed by adjusting options, even when using MaldiVes' premium features.
I discovered that the same graphical glitches started appearing in JoiPlay when I turned off the "Downscale Large Bitmaps" option. This led me to search the entire forum for the phrase "large bitmaps." Eventually, I found a thread
here for another game that suggested a solution.
I followed the proposed fix for MaldiVes by unzipping the attached archive and copying the files, replacing the existing ones. Miraculously, this solution worked, and I can now play the game in MaldiVes without any graphical glitches.
