(Questions Which Have Never Been Asked Before, As Opposed To Faq)

So what is Massacre?
As the name states it is an editor for editing the graphics in Master System (and compatible) roms.

Why make an editor for that system?
Because to my knowledge no editors for the Master System (and compatibles) exist.

Why is the damn thing so damn slow?!
Because you're using a version number < 0.5 :)

Where are all the bad guys in Phantasy Star?
I don't know!
The Master System seems to use two (at least slightly) different systems of storing image data.
One for sprites, and one for the other stuff... If someone could tell me how this other way
works I'd be very grateful.

Why did all my roms suddenly start malfunctioning?
Don't edit what does not look like graphics, and make backups!
