Redjac is a simple Commodore64 cross development tool for extracting or 'ripping' character sets (charsets) from VICE (v3.6 up) emulator snapshots, CCS64 (v3.9.2) emulator Freeze files or C64 whole memory dumps.
There is nothing this application can do that an experienced C64 coder can't do manually, so this is aimed at the more casual coder.
And, of course, it's coded in the brilliant PureBasic!
