Hello!
A group of people in a Discord server for JoJo’s Bizarre Adventure: Heritage For The Future (the CPS3 game) are taking the task of romhacking it.
Right now, we’ve gotten some really basic things, like modifying text and basic frame data changes for Star Platinum.
We also got some more advanced things, like giving Vanilla Ice and DIO new taunts, and sprite replacements for DIO, changing him to his first form (Or as some people calls him, “Jacket DIO”).
However, we cannot get a complete replacement of Jacket DIO, because his animations are incomplete (lack of certain sprites). These sprites, however, are used in a Mugen DIO. But since we have no way to add them without screwing up absolutely every sprite for DIO, a simpler way would be to find a sprite editor that works with CPS3 games. A similar program exists that can edit color palettes with the 51 file of the ROM.
The character sprites are located on in both 40 and 41 files of the ROM, and we were wondering if it would be possible to make a sprite editor for CPS3 games (or atleast this one), by opening these files, if such a program exists. Essentially it needs to be able to read rom sprite data, convert it to be editable or have the editing be done on the program, and then inject it back into the rom
If any of you that are seeing this know of one or know how to make one, that would be a great help to us.
Thanks a bunch.
