I haven't been around in quite a while, but I remember there was something which allowed you to change tilesets midway through your game to bypass the limit of Tileset A, B, C, D and E. Something along those lines anyway, I was never too fussed about it until now so didn't read all the details.
I'm sure it was some kind of utility but I honestly cannot remember where it was or what the name was. I've done a few searches but nothing has shown up. Am I just making this up or does such a thing really exist? I'm confident it does so any help as to it's whereabouts is greatly appreciated.
