To date, Hiei- is the only person who has actually succeeded in editing the title tiles and he doesn't remember how he did it. If I could edit the tiles, I would turn them white and I would create a proper "2" tile. If anyone can point me in the right direction for getting in there and editing any/all of this, I would be happy to make new tiles. Possibly an entirely new logo out of them.
From what I said in PM :
For example, I found in my log the title has been moved in the expanded part of the rom (0x230000), so near the intro (which has also been moved in the expanded part of the rom (0x251000).
I guess we modified a pointer somewhere to redirect it to 0x230000.
We also found the tilemap and palette of the title screen, I'll have to dig my logs about that too.
I can confirm I used LunarCompress/Decompress as I double checked and I listed them on the translation staff.
LUNAR COMPRESS: FUSOYA[NewLine]
LUNAR DECOMPRESS: FUSOYA[NewLine]
(But only for the title screen, the intro was decompressed/recompressed with a LUA script made by BahaBulle).
You might want to contact him, he's also the one who did the modifications to reinsert the censored boss (he explained me how to do the search/tests, I did them and he made the modifications), but not sure if he still has the sources.
You just had to check this adress in the rom with a Tile Editor and you would have known easily if it was compressed or not. Then, you had to calculate the pointer of the adress 0x230000 and search where the pointer is in the rom and it would have gave you the original title screen adress.
Compressed intro is at 0x251000 in my rom (I think I said it in PM). Original intro adresss seems to be x07B480 (from my logs)
Title screen is at 0x230000 in my rom. For the original adress, you can just search the pointer adress in my rom and you'll know where it is, but seems FuSoYa already gave the adress, 0x1CEA00.
