Alright. Still not use to making topics on these forums, but let's give it a jolly old go whatnot. :v: Whilst doing investigations for tools with a Master System project I've been doing some work for, I've been unable to find any standard Map Editors that can support Metatiles. I would trust almost anybody actually reading this topic - from this forum - to understand what I'm going on about, but for the uninitiated, I am referring to large tiles - say, 16x16 tiles, that're actually indexed to four smaller 8x8 tiles. For example, most of the Sonic games use 128x128 metatiles, that index back to 16x16 metatiles, which themselves index back to 8x8 tiles. Given the machine we're working on, and the fact we don't have unlimited ROM sizes, metatiles are a space saving we're very much taking advantage of. Anyway, all that much will be bleeding obvious to anyone reading this topic. What concerns me is if there is any mapping tools that can actually handle metatiles. I've looked through the likes of Tiled, and Mappy, but neither seem to quite support the concept. Whilst I've asked around in other quarters for if there's any tools that can handle them, I've generally not gotten positive answers from those I've asked. It would drastically speed up map design, having a tool that can handle these sorts of things live. Whilst we can probably manage without, it would be a real effort saver. Hope this isn't being a bother!
