Text and hexadecimal search includes a Find All results panel. CRC calculations can cover arbitrary memory ranges at 8, 16, 32 or 64 bits. Supported formats are Binary, ELF, Intel HEX, Motorola HEX, Tektronix HEX, TI-Text and Actel HEX, with C Array output available; ELF loading and C Array saving are one-way operations. The 32-bit version supports up to 1 GiB, while the 64-bit version supports up to 4 GiB of data. Downloads are listed for Windows 7, 10 and 11, and the interface supports 15 languages.
