Hello, First I apologize if my english is bad, because I'm french and english is difficult for me to write so I try m best. I'm not sure that my post is in the right place so I'm sorr if I mistake on the categorie. I'm asking for help to extract maps inside a Snes Rom because I'm a "soluce maker" and I try to make the best soluces for RPG game like "Tales of Phantasia" "Secret of evermore" but it take me very long time to build maps by taking screen with an emulator (I use Zsnes) and building them with Photoshop. I spend almost an entire 2 month of work to only build maps for "Tales of phantasia". So I'm searching over the net to see if someone know a little program to extract maps more easly. So I doesn't know if this is possible or if a tool already exist but maybe someone here ould help me. I thanks you to had take time to read this post. Thanks to all and have a nice day.  Salent

I don’t think it’d be so easy to get the map straight from the ROM. On the other hand, you could probably get someone to help hack the ROM for whatever game so that you can walk straight through everything and avoid random encounters. At least that would make it faster to get screenshots.
(I still make hand-drawn maps when I get lost in a video game!)

I'm understanding but I want to make soluce for many RPG game so it maybe more usefull for me to have an universal program whitch work for every Snes Rom, or like you say I must team up with a Rom hacker to help me ... but that may be a work for years ^^ (there is many RPG Rom).
So I think I continu searching but if I doesn't find anything I follow your words, thanks BRPXQZME.

You can try savestate viewers such as vSNES (see signature) or bgmapper to capture screens and tilemaps, especially Mode7 tilemaps. The problem is that some games don't use the hardware's scrolling abilities much. You could check out the maps at Piken's website, maybe they help you further. There are other sites that have these maps, for example vgmaps, snesmaps and this page. EDIT: fixed a link

Just out of curiosity... what is a "soluce" exactly? Is it a guide, or maybe an FAQ? A cheat code? Didn't show up in any French dictionaries (not translation engines) I looked at.

Ah. I guess the English term for that would be "walkthrough" though this seems to go a step further so I would call it a "visual walkthrough" or something similar.

“Une solution ou soluce est l'ensemble des indications permettant de finir un jeu vidéo sans s'attarder sur les différentes énigmes qui le composent.†- de Wikipédia, l’encyclopédie libre  My French is crap, I can only read it (much much worse than I could say about your English... in fact, the results would be trés embarrassant if I tried :laugh: ). But yeah, I suppose walkthrough is the closest English term. Still, it’s odd what people call game walkthroughs in different languages. In English, they can be called FAQ’s, strategies, and ... well, walkthrough, though of course each name gets applied to a different kind of guide. In Japanese, the term is generally 攻略 (kÅryaku), literally “capture†or “conquestâ€. No idea how that got decided on.

DLH.net uses "solution" as the translation for "Lösung" ... I don't know if it's used like that in English, too.

SO I have trying the little programs that Creaothceann give me but no one of them make what I want because I cannot take the whole map in one shot (thats what I want but I know that is maybe very difficult or impossible ... snif ) from the *.smc file (for exemple). The programs all use the *.zsx file (where x = 1 to 9) whitch are file with "frozen moment" of the game. I'm sorry because I know that my english is bad so the explanation that I give maybe difficulte to understand  SO I search an utilitie that can "take out" a whole map from a *.smc file if that is possible. If not then .. I take screenshot and do the usual way I know even if it take amount of time  But I thanks all the people who gave me an answer and tried to help me : Thanks a lot !! Good evening for all

Every game is going to have a different format for something like that. The best you could get is one program for each game you want to look at, but even doing one game is going to be a considerable amount of work.

The map data might even be packed with a game-specific compression algorithm.
PS: For perfect results, if you're combining a map with animated tiles, for example water, make sure that you get the right animation frame (the ocean in the Secret of Mana map on Piken's website shows what happens otherwise). But it'd be more work, of course.

In general, this cannot be done with a generic tool. Each game stores it's map data in a way that is particular to it's own custom game engine and any map rendering program has to be specifically written to parse that format.
That said, there are some options. If the map format is documented and you have some programming ability, you could write such a tool. (For example, I have written one for SMB Special to help with a project I'm part of.) If you plan on doing many such projects, a well designed program could be generic enough to allow for additional games with only the addition of a new map data parser.
Another option for those without the skills to write their own map renderer is to use programs written by others. If the game you're working with has had a level editor written for it, you should be able to use it to capture screenshots of larger areas at once, if not the whole map.
Beyond that, I'm not sure there's much else you can do. With console games, especially for older systems, pretty much all the data is in a format specific to that game, so generic tools to manipulate that data don't exist. (There are exceptions, but map data isn't one of them.)
