How does everyone feel about making a page for each system that would list all the known (dumped or not) unlicensed games categorized by system?
I know that would be a daunting task for something like the Famicom, but both the 16-bit systems and some of the handhelds wouldn't be too bad. Maybe just have a table with name, release year, publisher/developer, and genre?
Or possibly make a page with a listing of hacks that aren't really original enough to warrant a single page entry, but just have some basic info regarding what game they're based on and the changes made to them?
Both of those ideas would be something that once the initial page was made, edits could be made that would take minimal effort to update with new information. Plus it might generate more visitors to the wiki by having it show up more often in search engine results.
