Ahh cool, thanks so much for the explanation. Now I know what it is I'm looking for (never heard of a RAM map before but the concept makes sense) I managed to find one somebody else was working on: https://dl.dropboxusercontent.com/u/29210231/RAM_Map.txt I'm not sure how complete or accurate it is, but it looks like it'll be worth me reading through because hopefully I can get the information I need from this, all I really need is a few things like players coordinates and current map name/number, simple stuff. I'll have a read through of this and report back.

Hey guys, some helpful fellow over at romhacking.net pointed me over here in the hopes you might be able to help me. I'm a software developer whos agreed to write a small program for someone, the basic idea is that when the player hits a trigger in the game, or acquires an item, etc, my program will pick up on that information and then trigger a real-world sound, stage light, video, whatever. I've got everything else covered, but the crucial part I haven't got a clue how to start on, and I was hoping that using an emulator with LUA script might be a good lead. Here's an example of the sort of thing I'm looking to do: Player picks up a specific item or enters a specific room -> the emulator/lua script detects this and informs my program -> my program then does whatever it's supposed to do in that event, playing a sound effect for example. Does anybody know where I might be able to find further information about getting that data out of Link to the Past while it's being played? I'm thinking that accessing the games memory won't be too much of a hassle, especially if I just directly modify the emulators source code. I just have no idea where to start looking in memory for the information I need, things like equipped items, players x/y coordinates, current map, etc. Thanks in advance for any help or advice, and I apologize profusely if this is in the wrong subforum.
