USB Display firmware + U-disk tool

For MacroSilicon USB display combined .bin images (e.g. MS9133_DEMO_*_add_udisk_*.bin):

• Parse: split firmware, list FAT files, MD5 and ZIP export
• Pack: upload fw.bin and U-disk files into a fixed 8 MB / 16 MB layout

Use case: MacroSilicon USB Display solutions with a USB disk partition in combined images (e.g. MS9133_DEMO_*_add_udisk_*.bin). The leading section is firmware; the trailing section is a FAT file system.

Disclaimer: This tool is not an official vendor utility; this site provides no warranty; parse and export outcomes are your sole responsibility. Fully verify on target hardware before production or flashing.

FAT offset: MS912x / MS912xS typically 0x02000; MS9132 / MS9133 typically 0x32000. Actual offset is auto-detected during parse.
