Create new or edit existing ZX-Spectrum emulator files. Use a powerful data block composer to add, insert or modify data blocks for any compatible file type. Edit tape files, disk files, picture files, snapshot files etc. Edit contents of SCREEN$ blocks, Basic programs and variables with ZX-Paintbrush and ZX-Editor with embedded dialogs. You can send data blocks to other ZX-Modules programs.
ZX-Editor is a text editor for ZX-Spectrum emulator files, which supports (nearly all) functions you know from other text editors, and also Spectrum-related things like colour attributes, flashing, screen$-files etc. You also can change the text style (italic, bold etc.) as well as text height. But also 8×8-pixels fonts are supported.
ZX-Paintbrush is a Microsoft Windows program that allows the user to create new screen files, draw images using mouse-sensitive tools such as polygons, circles, rectangles, etc. It offers various fill styles in tool boxes and allows the user to easily alter the color attributes. Using ZX-Paintbrush, it is also possible to convert BMP, GIF, JPG files and also to hold them in this format.
In NextZXOS v2.7 + you can edit the default menu items that appear on start up. This is done my configuring a configuration file in "c:\nextzxos\enMenus.cfg"
Normally you would have to edit with a text editor such as qe - but that can be a little tricky for new-comers so this tool attempts to bridge that gap.
