Megadrive-Vector-Table-Reader

This is a small tool which will parse the 68k vector table of a specified Mega Drive ROM and output it in a human readable format.

Usage

Usage: mdvtr.exe file [options]
  options:
    -b, --bit-padding:       Determines the padding for the output vector/s.
                             Bit padding must be supplied in decimal, must be a multiple of 4 and the following must apply 0 <= padding <= 32. [default: 32]
    -o, --offset:            If specified, only outputs the vector at the given offset.
                             Offset must be supplied in hexadecimal, must be a multiple of 0x4 and the following must apply 0x0 <= offset <= 0xfc. Allowed syntax: 0xXX or XX
    -p, --prefix:            Specify the prefix for the output vector/s [default: "0x"]
    -i, --ignore-identifier: Disables validating input files by checking for string "SEGA" at offset 0x100.
    -v, --version:           Display version info.

Sample usage:

mdvtr.exe "Streets of Rage 2 (USA).md" -p "$" -b 16 -o 0x4
$0208
