bin2tap.py

bin2tap.py converts a binary file produced by an assembler (see Supported assemblers) into a TAP file that can be loaded into an emulator. For example:

$ bin2tap.py game.bin

will create a file called game.tap. By default, the origin address (the address of the first byte of code or data), the start address (the first byte of code to run) and the stack pointer are set to 65536 minus the length of game.bin. These defaults can be changed by passing options to bin2tap.py. Run it with no arguments to see the list of available options:

Usage: bin2tap.py [options] FILE.bin

  Convert a binary snapshot file into a TAP file.

Options:
  -o ORG      Set the origin (default: 65536 - length of FILE.bin)
  -s START    Set the start address to JP to (default: ORG)
  -p STACK    Set the stack pointer (default: ORG)
  -t TAPFILE  Set the TAP filename (default: FILE.tap)

Note that the ROM tape loading routine at 1366 ($0556) and the load routine used by bin2tap.py together require 14 bytes for stack operations, and so STACK must be at least 16384+14=16398 ($400E). This means that if ORG is less than 16398, you should use the -p option to set the stack pointer to something appropriate. If the main data block (derived from game.bin) overlaps any of the last four bytes of the stack, bin2tap.py will replace those bytes with the values required by the tape loading routine for correct operation upon returning. Stack operations will overwrite the bytes in the address range STACK-14 to STACK-1 inclusive, so those addresses should not be used to store essential code or data.

New in version 1.3.1.

Changed in version 2.2.5: Added the -p option.

skool2asm.py

skool2asm.py converts a skool file into an ASM file that can be fed to an assembler (see Supported assemblers). For example:

$ skool2asm.py game.skool > game.asm

skool2asm.py supports many options; run it with no arguments to see a list:

Usage: skool2asm.py [options] FILE

  Convert a skool file into an ASM file, written to standard output. FILE may
  be a regular file, or '-' for standard input.

Options:
  -q    Be quiet
  -w    Suppress warnings
  -d    Use CR+LF to end lines
  -t    Use tab to indent instructions (default indentation is 2 spaces)
  -l    Write disassembly in lower case
  -u    Write disassembly in upper case
  -D    Write disassembly in decimal
  -H    Write disassembly in hexadecimal
  -i N  Set instruction field width to N (default=23)
  -f N  Apply fixes:
          N=0: None (default)
          N=1: @ofix only
          N=2: @ofix and @bfix
          N=3: @ofix, @bfix and @rfix (implies -r)
  -c    Create default labels for unlabelled instructions
  -s    Use safe substitutions (@ssub)
  -r    Use relocatability substitutions too (@rsub) (implies '-f 1')

See ASM modes and directives for a description of the @ssub and @rsub substitution modes, and the @ofix, @bfix and @rfix bugfix modes.

Changed in version 1.1: Added the -c option.

Changed in version 2.1.1: Added the -u, -D and -H options.

Changed in version 2.2.2: Added the ability to read a skool file from standard input.

skool2ctl.py

skool2ctl.py converts a skool file into a control file. For example:

$ skool2ctl.py game.skool > game.ctl

In addition to block types and addresses, game.ctl will contain block titles, block descriptions, registers, mid-block comments, block end comments, sub-block types and addresses, instruction-level comments, and some ASM directives.

To list the options supported by skool2ctl.py, run it with no arguments:

Usage: skool2ctl.py [options] FILE

  Convert a skool file into a control file, written to standard output. FILE
  may be a regular file, or '-' for standard input.

Options:
  -w X  Write only these elements, where X is one or more of:
          b = block types and addresses
          t = block titles
          d = block descriptions
          r = registers
          m = mid-block comments and block end comments
          s = sub-block types and addresses
          c = instruction-level comments
  -h    Write addresses in hexadecimal format
  -a    Do not write ASM directives

If you need to preserve any elements that control files do not support (such as data definition entries and ASM block directives), consider using skool2sft.py to create a skool file template instead.

New in version 1.1.

Changed in version 2.0.6: Added the -h option.

Changed in version 2.2.2: Added the ability to read a skool file from standard input.

Changed in version 2.4: Added the -a option and the ability to preserve some ASM directives.

skool2html.py

skool2html.py converts a skool file (and its associated ref files, if any exist) into a browsable disassembly in HTML format.

For example:

$ skool2html.py game.skool

will convert the file game.skool into a bunch of HTML files. If any files named game*.ref (e.g. game.ref, game-bugs.ref, game-pokes.ref and so on) also exist, they will be used to provide further information to the conversion process.

skool2html.py can operate directly on ref files, too. For example:

$ skool2html.py game.ref

In this case, the skool file declared in the [Config] section of game.ref will be used; if no skool file is declared in game.ref, game.skool will be used if it exists. In addition, any existing files besides game.ref that are named game*.ref (e.g. game-bugs.ref, game-pokes.ref and so on) will also be used.

skool2html.py supports several options; run it with no arguments to see a list:

Usage: skool2html.py [options] FILE [FILE...]

  Convert skool files and ref files to HTML. FILE may be a regular file, or '-'
  for standard input.

Options:
  -V        Show SkoolKit version number and exit
  -q        Be quiet
  -t        Show timings
  -d DIR    Write files in this directory (default is '.')
  -o        Overwrite existing image files
  -l        Write disassembly in lower case
  -u        Write disassembly in upper case
  -D        Write disassembly in decimal
  -H        Write disassembly in hexadecimal
  -c S/L    Add the line 'L' to the ref file section 'S'; this option may be
            used multiple times
  -P PAGES  Write only these custom pages (when '-w P' is specified); PAGES
            should be a comma-separated list of IDs of pages defined in [Page:*]
            sections in the ref file(s)
  -w X      Write only these files, where X is one or more of:
              B = Graphic glitches
              b = Bugs
              c = Changelog
              d = Disassembly files
              G = Game status buffer
              g = Graphics
              i = Disassembly index
              m = Memory maps
              o = Other code
              P = Pages defined in the ref file(s)
              p = Pokes
              t = Trivia
              y = Glossary

When skool2html.py is run, it looks for skool files, ref files, CSS files, JavaScript files and font files required by the disassembly in the following directories, in the order listed:

  • The directory that contains the skool or ref file named on the command line
  • The current working directory
  • ./resources
  • ~/.skoolkit
  • /usr/share/skoolkit
