This format can save many record in one file and support all casio kind of data. G1r files are ended by .g1r In this format, programs are stored in the raw format, inside a bloc of metadata with a fix size. Those metadata contain the name of the program and if the program use bas operations or not. Programs and metadata can be extracted from a g1r file with a regular expression (here in pyt… text/html 2010-08-19T13:35:24+00:00 Florian Birée http://casetta.tuxfamily.org/fr/presentation?rev=1282224924&do=diff Autres langues : English Nouveautés * 8 août 2010 : les logiciels Casetta ne sont plus développés activement (cependant, ils fonctionnent toujours).

In fact, the content of a cas file is the raw dump of received data from a calculator. Because of changes in transfers between old and new casio models, some softwares (like CaS) save data from new casio models in as data are transferred, so it's not compatible with old casio cas files (as described bellow).
