In MinimugPalette, It is using the bottom 0x200 of the text buffer, which seems to be incompatible with the translation patch.
Using Soundroom buffer 0x201F148 solved the problem.
This is with FE8J, but maybe there is a similar problem with FE8U.

0x201F148 is the same address for both FE8J and FE8U.
This is where the random mode song id, etc. in the sound room are stored.
After that, there is a 0x00 area that goes all the way to 0x00, which I am not sure what it is used for.
It doesn’t seem to matter if I use 0x200 bytes.
If you have a problem with this area, you might be able to use the Network arena area.
