UDGee – Sprite Editor
UDGee is a handy sprite editor by forum member ‘emook‘, and makes use of the full 256 colours palette of the Spectrum Next. Check out the step by step instructions on the video, using the ZEsarUX emulator as the Spectrum Next alternative.
Follow the thread in the forums for the latest updates, as UDGee is very much work in progress at the moment, even though it already looks awesome.
