// BIN2ISO (C) 2000 by DeXT
//
// This is a very simple utility to convert a BIN image (either RAW/2352 or Mode2/2336 format)
// to standard ISO format (2048 b/s). Structure of images are as follows:
//
// Mode 1 (2352): Sync (12), Address (3), Mode (1), Data (2048), ECC (288)
// Mode 2 (2352): Sync (12), Address (3), Mode (1), Subheader (, Data (2048), ECC (280)
// Mode 2 (2336): Subheader (, Data (2048), ECC (280)
//
// Mode2/2336 is the same as Mode2/2352 but without header (sync+addr+mode)
// Sector size is detected by the presence of Sync data
// Mode is detected from Mode field
//
// Tip for Mac users: for Mode2 tracks preserve Subheader
// (sub 8 from seek_header and write 2056 bytes per sector)
//
//
// Changelog:
//
// 2000/11/16 - added mode detection for RAW data images (adds Mode2/2352 support)
//
//
