[Other] A Few Questions from a New Hacker

[whitenoize]

So after being a fly on the wall in this community for quite some time I decided to finally join as I have been planning a new rom hack. I want to make my hack original however and am here to ask about some functions that I am unsure if I would be able to implement:

1.) Is there a size limit for hacking a rom? (Ex. Implement a dual-region system such as in gold/silver but in fire red/leaf green)

2.) Can the story be player driven (ex. Different events for if player selects Yes/No during a dialogue)?

3.) Is there a way to allow the player to create more than one save file (not save state in emulators)?

Note: If these questions have been answered before please provide me with the answer because I have been having a difficult time finding those answers. Thank you.

1 - Yeah. Generally people insert second regions over the Sevii Islands.

2 - Player Driven stories are possible, it's simply a matter of using flags. Conceptually, it's really simple.

Thanks for the quick reply machomuu. My biggest concern with the player driven flag sequence was also the size limit for having too many flags and events as alternate routes to take.

Having all those flags does however force people to make many save states to really experience the full game instead of starting over multiple times. Hopefully there is a way to copy/erase/create more than one save file.
