This is possibly because the translation rom changes the reg_waitcnt by accident. I am doing the game's decomp project and here is where the translated rom changes: https://github.com/Cofflag/csm3/blob/a1a80a8a3e46b6da3dab6f5ef4a6ee1b0dba614f/src/main.c#L372 in the binary, the original constant is 0x4014 and the translated version is 0x4000, and the offset of the literal pool is 0x1ba0 the problem should get fixed by editing the rom to recover the original value.
I mean Cofflag already provided the solution, and it works. This problem can be fixed by editing the rom, you can use a hex editor like HxD to change this value from 00 to its original value in Japanese version: 14.
就照着 Cofflag 说的做，用HxD这类的十六进制编辑器把汉化版的1BA0的值从00改成日版原始值14就修好了。
至少我这边修改后简单测试的结果，3个及以上敌人的战斗没有再遇到卡顿问题，你可以试试。
Before(mGBA 0.10.3):

I finally tested this on a real GBA and can confirm that the issue is the ROM hack itself, not mGBA.
