Here are some game maps I have made. In general, they are not so much aimed at providing a walkthrough or a cheating guide, as at providing an overview of the game worlds, and to enable appreciation of the design and artwork that goes into games.
These days I'm more likely to add any maps I make directly to the SMS Power maps section... so this section will remain just as an archive of my older maps.
Note that I go to a lot of effort when making them, including hacking games to access unaccessible areas, remove status displays, etc. By doing that I can make clear maps without the main sprite appearing hundreds of times. So if you use them for something, please let me know and please give credit where it's due. Enjoy!
There's also the WIP maps page where there's some somewhat-aborted work.
