- SPCONV 1.0 - 10 AUG 1992 - Convert snapshot files (.SNA, .SP, .Z80 and RAW)
-
- Usage:
-
- SPCONV <infile> <outfile>
-
- Spconv is a utility to convert between various snapshot formats. Snapshot
- files are created by various spectrum emulators. SPCONV converts between .SNA,
- .SP and .Z80 files. The conversion to/from .SP files may not work always
- however, it is not clear to me how IFF, IFF2 and the interrupt mode are stored
- in the .SP file. Cashing of a converted image may also be caused by bugs in the
- SPECTRUM emulator. Converion to .SP will work if the image is converted from a
- RAW image (see later)
-
- Normaly the <infile> and <outfile> are not of the same type. If they are you
- will get a error message, unless both files are of the .SP type. In that case
- the converter will convert an old style .SP file to a new style .SP file or form
- a new style .SP file to an old style .SP file, depending on the input. The old
- style .SP file is used by VGASPEC, with seems to be an unauthorised version
- of the spanish "SPECTRUM". The "SPECTRUM" will use the new style .SP files.
-
- Conversion between .SNA and .Z80 and from .Z80 to .SNA should be no problem,
- both formats are sufficiently described in the documentation of JPP (the
- norwegian emulator) and Z80 (the dutch emulator).
-
- Spconv can also be used to convert a raw spectrum image to a snapshot file.
- The image has to be captured with a program that reads the RS232 port and
- puts the read data in a file. At the Spectrum side the the command
-
- SAVE *"b"CODE 16384,49152
-
- HAS to be used. Convert will convert the file is such way that it will continue
- in the basic interpreter. so
-
- SAVE *"b"CODE 16384,49152:PRINT "Hello, World!"
-
- will after conversion to a snapshot file and loading it in the emulator, begin
- with printing "Hello, World!".
-
- Example: Converting a .SNA JPP file to the .Z80 Dutch emulator:
-
- spconv game.sna game.z80
