Tool for edit GDUs and Fonts for ZX Spectrum 48K/128K. With this editor you can create custom UDGs and fonts.
The editor can handle files with the following extensions:
.udg: (User Defined Graphics) It's an array of 168 bytes (21 characters x 8 lines each one) with the raw definition of this UDGs.
.gdu: From the spanish "Graficos Definidos por el Usuario", it's the same than .udg
.fnt: Personalized font. And array of 768 bytes (96 characters x 8 lines each one) width the raw definition of the alternate charset.
In addition to allowing editing of these file types, data can be exported in .tap format for loading from an emulator (thanks to the export routine that has been developed by Hash6iron) or .bas, a format specifically designed for use in ZX Boriel Basic.
We are working on expanding functionalities and we would like to hear your opinion.
