YY-CHR

From Nesdev wiki

What is YY-CHR and where can I download it?

YY-CHR is another CHR editor by a japanese Mario hacker named YY. It's for multiple systems but has more features than Tile Layer Pro, It used to be a HSP (Hot Soup Processor) program, but due to false virus warnings. It has moved to C++

You can download it here at: YY-CHR v0.99 (C++)

Old Version: YY-CHR v0.98 (last HSP version)

Thanks goes to YY for the new links.
