I’m working on a proof of concept for a hack, and as i got further along with it, i realized that the size limitations of the ROM would hold me back. I know ROM Hacks like "Sacred Trilogy really push the amount of space on the ROM so i was curious as to how far i could go.
I don’t necessarily want to spoil what i’m doing or work on it only to give it up soon after. So if my questions seem crazy, its because this idea is crazy. It will just be a proof of concept and hopefully if it works as well as i’d like it to, i can pass it on for someone else make something out of it.
I know the amount of maps i can use are finite in the ROM and i’m investigating a way around this by splitting the ROM into two parts where when you complete one half of the ROM, you move your save file over to the other and use some event coding to warp you back to the first chapter (which won’t actually be the first chapter.)
How many characters can I actually have? Because i plan to have… over 150-200. I know there is a lot of empty character slots in the ROM labeled as “Enemy” which can be repurposed but i want to know if i can expand this further beyond the normal. I was playing around with the skills patch and was able to increase the character list beyond FF, but i’m not sure what repercussions come with this. I added character in those new slots and they seemed to appear just fine.
How many portraits and animations can I import into the game? Just like the character slots, i know that there is finite space on the ROM and that is the main limiting factor to things like this.
This isn’t specific to this hack but there are some FE hacks that won’t save when playing them on a flashcart on actual hardware, most notably, Sacred Trilogy. I would like to be able to test it on my actual gameboy but i’m worried that the file will get to big and saving will become an issue.
So, is what i’m doing too crazy and i should just give up, or exactly how big can i get the ROM to be before it all breaks down?
