These tiles have been taken from various 8-bit Castlevania games including CV1, VK, CV2, CVA, and CV3: Dracula's Curse. I wish to point out beforehand that these are all using the colour pallete of SMAS SMB3 and again this ties back into that idea.
I made most of these myself, using the map tiles from SMB3 and some official (and other sources) as a reference.
Out of all the original 8-bit Monsters I upshaded, I consider my work on the Cyclops to be a masterpiece.
Aw yes, Richter Belmont. One of my favourite Belmonts and he'll have an important role in this crazy idea of mine. I must point out that I used the "8-bit Richter" sprites I found in the sprites section of the CVRPG website and upshaded them. I am dismayed at the fact that the author of the original sprites didn't put his name on his sheet so I could credit him properly. I got the climbing sprites from another sheet, again without an author's name on it.
Trevor Belmont, another favourite of mine. I think I did a good job upshading him regarding the pallete I had to work with
This is a fine example of my tilesets
