You have to invert the pointers given to you: 0x1D88B4 is given for the battle frame, so we break that down into individual bytes 00 1D 88 B4. For pointers, you add 0x8000000, so that makes it 08 1D 88 B4. Then reverse the bytes, like so: B4 88 1D 08. Run a “replace all” on those hex values, and do the same process for every pointer given.
There’s a lovely topic that’ll come up when you type “free space” in the search bar.
So if you just import the battle frame to 0xD00000, you’d run that replace all function and replace with 00 00 D0 08. After importing the first piece, go to that offset to see how long the data runs and pick up at the next available offset (when it goes back to being 00s and FFs primarily is when the free space starts again).
Additionally there’s a tutorial further explaining repointing (you could’ve found it by typing “repoint” into the search bar).
