I’m surprised nobody has written a review for this one! This is an editor which pound for pound gives you everything you need to do your own Metroid hack with powerful options. Also with the editor you can expand your Metroid ROM giving you even more much needed space to have more of a variety of screens to create instead of using the same ones multiple times. You can also create your structures with ease and Editroid will show you which tiles are solid, breakable, and transparent so you can make the right types of block placements and platforms. Get this program and make something great!
