ROM Hack Tales of Phantasia GBA Tilemaps ripped after 7 years of trying!

[TwoSpikedHands]

Hey all, just wanted to give a little status update on some progress I've made on reverse engineering as I'm a tad bit excited
Today I have successfully decompressed and reverse engineered Tales of Phantasia GBA to the point where I can now load in my own custom maps!
Here's a little test map I made:

This map is essentially a copy of another map, modified, then placed into a section of free space to be loaded (for now) manually.
I eventually have plans to force the game to load it by itself without needing me to intervene, but that'll be at least a few weeks down the line since I have a new job.

I say this took 7 years because 7 years ago I posted on this forum and kinda gave up XD
Glad I came back to it!

Will thy knowledge be shared, perchance?

Yep, here's my post where I shared it
https://gbatemp.net/threads/tales-of-phantasia-gba-romhacking-effort.648958/

Long story short I've decided to change over to the EU version instead (it has better sound quality in voice lines and brighter colors, as well as other features), so I will essentially need to remake ALL of this data, as the locations in ROM are now incorrect. But most of the data is still correct

I'll eventually repost my findings as it's all in a new document
