Hacking Boktai 2 won't save on EZ4

[Prof. 9]

I've tried booting it from the GBA loader and YSMenu (R4), but I can't get it to save. Whenever I try to save, it just gives me an error. Am I doing something wrong? I ran it through the EZ4 Client (the latest) after patching it with the solar sensor fix...

Well, I finally got it to save. Here's what I did:

- Patched the EU rom with Hiei-YYH's patch instead of No Frills' patch
- Ran it through the EZ4 Client, Add Save Patch checked, Reset unchecked
- Booted it from YSMenu.
