Title: Mr Dos castle and Centipede flip video
Post by: BladeZX on February 17, 2020, 07:14:43 pm
I have been trying to find a rom hack to flip the video 180 degrees for Mr Dos Castle and Centipede
Does this exist?
I can write new roms if needed
Thanks

Are you referring to the arcade versions, or the versions for some other console?

I think there are some versions of MAME that can already do video flipping.  Otherwise, I expect rewriting the code for arcade games running on unique hardware is likely to be an enormous challenge.

Arcade versions
JROK flipped Mr Do in this link

I am hoping to figure out how to flip Mr Dos Castle as well
and then hopefully Centipede

It is very useful to indicate pre-existing work.  I didn't realize you were talking about vertical flipping; that is probably slightly less problematic.

But are you planning to burn new ROMs for an arcade board?  Because like I said, if you just want to do this in MAME, there's probably an easier way.
