For example:Ĥ987 (decimal) = 137b (hexadecimal).
In other words, the least significant bit is stored first. Larger integers in the ROM are encoded in “Little Endian” format. Hexidecimal numbers will appear in this format: 137b. When providing addresses in the ROM, I will precede the address by a “ 0x“.ĭecimal numbers will appear in this format: 4987. I assume that you understand basic hexidecimal theory here. The link provided also documents its features. I also recommend getting a copy of the VBA Debugging Emulator I used, in case you plan to do your own testing and debugging on the ROM’s code. To continue using it, you’ll need to purchase it. The link I provide is to a 35-day trial version of the software. I recommend Hex Workshop 4.1', if you don’t already have one. You’ll need to have proper tools for these notes to be of any help.
While I don’t absolutely guarantee 100% veracity, I did create my mod in conjunction with the notes presented here, and they should be quite precise. I didn’t use any tools other than a hex editor, and a debugging version of Game Boy Advance for stubborn little issues and hard-coded aspects of the game (like the 999-HP/MP limits). They’ll be of help for you to find some of the various data lists are stored in the ROM, and though my list is by no means comprehensive, the notes served as my brain as I waded through the hexidecimal code. I spent a fair amount of time amassing these notes. However, some intrepid reader using the forthcoming notes could pull that off. Thank you.Īs I have a number of other projects which I am currently working on, it is not looking like I will be writing a Hackster for FF1 GBA. Please do not repost this material elsewhere without asking me. Feel free to make creative use of any and all of it in your endeavors, however, if you do use this info to glean insight for your project, I would appreciate appropriate recognition for my original effort. I offer these notes in the hopes that they are of use to you, and to the greater modding community. Thank you to those of you who requested this info, and for your patience with me.
