- Fu's pipes don't use blocktool at all.
- You don't put the .bin files in block tool.
You're not inserting them properly...
BUT YOU SHOULD KEEP A BACKUP ALWAYS! Or else it may DIE.
The .bin file is the ASM used for the pipes, not a block tool block, you have to place it in an empty bank in the ROM (addres x98200 is the most used), then change addreses x3789X to 22 40 80, x378AX to 22 80 80 and x378BX to 22 80 C0.
(Where X is 0 if you haven't inserted custom blocks or 4 if you HAD inserted custom blocks).
