I am looking at making a CHR-RAM hack, But there are just about no documents on CHR-RAM.

Does anyone have a document about how CHR-RAM works?

im gonna assume your talking about the NES. are you trying to convert a rom from chr-rom to chr-ram or editing an existing chr-ram game?

to write to chr-ram, you need to set the vram destination pointer (via $2006) and write your data with $2007. all of this needs to be done durring vblank or when rendering is disabled.
