TODO

• Refactor Code
• Reading images directly from the cartridge (without opening a .SAV file).
• For BMP, avoid using memory to generate images; write directly to files.
• Exhibit and view images through a Web Server interface.
• Add frames to images.
• Configure dimension upscaling.
• Export to other file formats.
• Extract Game Faces.
