Capture the C64 screen as a PNG image. Auto-detects the active graphics mode and renders accordingly. Supported modes: Standard Text (40x25), Multicolor Text, Extended Background Color (ECM), Standard Bitmap (Hires 320x200), and Multicolor Bitmap (160x200). Returns base64 encoded PNG data with mode info.

Type text into the C64 keyboard buffer. Converts ASCII to PETSCII and writes to the keyboard buffer at $0277. The C64 will process these keystrokes. Automatically handles text longer than 10 chars by chunking. Use {RETURN} for newline, {CLR} to clear screen, {HOME} for home, {UP}/{DOWN}/{LEFT}/{RIGHT} for cursor, {F1}-{F8} for function keys, {DEL}/{INS} for delete/insert.

Send a special key to the C64 keyboard buffer. For control keys that can't be easily typed as text.
