(Hope so.) +5) Can repair some invalid images. +6) Now also supports DI file format. + +Thanks go to: +Ernest Schreurs for his DiskCommunicator dissection and paper about DCM format. +Chad Wagner for DCMtoATR utility (DCM driver is still loosely based on his + code). +Burian brothers for lots of DI files. + + +Usage: +------ +Acvt [options] sourcefile [destfile] + +sourcefile is Atari disk image (ATR,XFD,SCP,DCM,DI). + +destfile is output disk image. If omitted, output filename is created + automatically. + +-xfd -atr -scp -dcm -di options are output type modes. Default is -atr. + +-batchmode: turns on multi file processing mode. Only input files are specified + on command-line (Unix-like compatible regexp expressions are allowed when + compiled under DJGPP). Output filenames are created automatically. + +-autorepair: automatically determines the best repair method. + +-norepair: doesn't ask for repair options and considers input file invalid. + +-errstop: in batch mode ends on first error encountered. + +-over: overwrites existing files. Otherwise returns an error. + +-test: only loads input images and displays their state. + +-classic: forces to create 'classic' Atari disk sizes. + + +History: +-------- +Date, Author, Version +5/22/1999, kubecj, 0.10 +First version + +5/25/1999, kubecj, 0.15 +SCP save added + +5/29/1999, kubecj, 0.20 +DCM save added, decompression corrected + +5/30/1999, kubecj, 0.30 +Code cleanup + +6/1/1999, kubecj, 0.35 +Invalid DD ATR repair added + +6/2/1999, kubecj, 0.40 +Invalid DD XFD repair added +Invalid ATR length repair added +Added cached read for DCM decompression + +6/3/1999, kubecj, 0.42 +Code cleanup + +6/4/1999, kubecj, 0.43 +Added checks for DCM decompression +Check for multi-arc + +6/5/1999, kubecj, 1.00 +First public version + +6/10/1999, kubecj, 1.01 +Compatibility macros & valid archive :) + +6/11/1999, kubecj, 1.02 +Repaired repairing ;) + +6/13/1999, kubecj, 1.03 +Changed switches processing + +10/10/1999, kubecj, 1.04 +Only changed generation of archive, new version to avoid version checking +problems. + +6/6/2000, kubecj, 1.05 +Minor bugfix concerning repairing. +Added -classic commandline switch to force to create 'classic' disk sizes. + +2/26/2001, kubecj, 1.06 +Added DI file format. Its support is just a beta! + +3/8/2001, kubecj, 1.07 +Handling of double sided diskettes in DI format. + + +To Do: +------ +Maybe check pass count in DCM images? +Better handling of DI files. + + +Known Bugs: +----------- +DCM record 0x42 is not decompressed, code is present, but commented out and + untested. I need some sample first. + +DI files are really an educated guess. There are many 'white places' for me. +I need the description of the disk format. + +Function for actual conversion is stupid. In fact in order to convert ATR to + XFD there is created Atr object, loaded in, and same Xfd object is created and + all the data are duplicated. With 16MB SpartaDOS Atr images it's simply too + much. + + +Compiling Tools: +---------------- +For scripts: Perl. +URL: http://www.perl.com + +For PC executables: DJGPP. +Sources were written/tested on GCC/Intel only. There should be only +minor problems to port it to different architectures/environments. +Makefile should need only minor changes. +URL: http://www.delorie.com + + |
