Orex

Orex will be a web-based NES CHR ROM pattern table viewer and editor. Currently, it is only a viewer. There are a few limitations:

• Orex can only display CHR ROM, not CHR RAM.
• Orex cannot display pattern tables for NES files that have no CHR ROM, but it still prints out useful info from the file header.
• Orex is currently an ugly mess that I wrote in one evening; It will improve quickly may improve one day.
• A four-color palette is used for practical and aesthetic reasons, but no specific hues are read from, or written to, the CHR ROM.
