The background of the room that Richter fights with the Necromancer / Ghost Boss, from Castlevania : Dracula X. Since the background is very wide, I could only rip part of it. I also needed to create two extra tiles to make the background loop correctly. Use it for haunted levels ou maybe a creepy cave.
Warning! It uses three palette rows (2,3,4) and all the Background slots (BG1,BG2,BG3). Proceed with caution.
