VDC Screen Editor 2 (C128)

VDC Screen Editor v2 is an editor to create text based screens for the Commodore 128 VDC 80 column mode. It fully supports using user defined character sets and allows the use of two 256 character character sets at the same time.

Main features of the program:

• Support for screen maps larger than the screensize of the present screenmode. Screens can be up to 30 KiB (30.720 bytes), all sizes fitting in that memory are supported. NB: As both the character data as the attribute data needs to be stored, a screen takes width times height times 2 bytes in storage. So 30k would fit up to 7 standard 80x25 screens to be distributed over width and height, so e.g. 2 screens wide and 3 screens high (160x75 characters).
• Support multiple screenmodes, including a 80x50 mode ideal for PETSCII art. Note that the largest screenmodes of 80x70 PAL or 80x60 NTSC need 64 KB VDC RAM and a monitor supporting it.
• Integrated file browser.
• Supports resizing canvas size, clear or fill the canvas
• Support for loading two user defined charsets (standard charset and alternate charset, should be standard 'C64' charsets of 256 characters of 8 bits width and 8 bits height).
• Includes a simple character editor to change characters on the fly and directly see the result in your designed screen (for editing a full character set one of the many alternatives for C64 character set editing is suggested).
• Supports all the attribute values the VDC offers, blink, underline, reverse and alternate character set. For example the reverse attribute removes the need to have a reverse copy of every character set stored in the upper 128 positions of the character set, creating more positions that can be freely used to design own graphics.
• 64KiB VDC memory only: An undo/redo system is included with up to 40 positions to go back or forward (depending on the size of the change in characters). As this uses a lot of memory, this feature is only available if 64 KiB of VDC memory is available (such as in the C128DCR).
• Write mode to freely type characters with the keyboard, supporting all printable PETSCII characters and also supporting Commodore or Control + 0-9 keys for selecting colors and RVS On/Off
• Color write mode to freely type attributes and colors
• Line and box mode for drawing lines and boxes
• Select mode to cut, copy, delete or repaint (only color or all attributes) the selection.
• Move mode to scroll the screen contents (due to memory constraints only for the 80x25 viewport)
• Import from PRG screen memory dumps and import from and export to SEQ PETSCII sequences.
