I ´m not an expert in these things, but normally you got these errors when extracting didn ´t work correctly. Ths might be caused when the program you used struggles with letters that it can ´t decode and often happens with japanese games. This one is in english and I remember I had no errors while playing, you can try to install it again, always make sure to use 7zip for extracting, Bandizip works well too. If that doesn ´t help I ´ve no clue how to solve this.
Try to locate that file, Mimi Battle.png at the img/sv_enemies/ folder location and see if it is even present. If not present, you probably will need to check if your download got corrupted (see if that PNG image is present inside the ZIP file).
so i had a look, the file is present but its in pictures. can i just copy and paste it in the enemy folder or would that cause issues?
I don't see how that could cause a problem if the file isn't there already. The most it could do is look bad if the image has drastically different dimensions. If it somehow causes an issue, just remove the file you added.
Mc is absolutely not either of those things, like, not even a little bit
You can get a big number of them pregnant and multiple times too.
