Address Format

All tools accept addresses as hex strings or integers:

• Motorola: "$FF0000" (preferred for M68000)
• C-style: "0xFF0000"
• Zilog: "FF0000h" (for Z80)
• Integer: 16711680 (a bare number without $, 0x or h is always decimal)

All returned addresses use the Motorola $XXXXXX convention.
