Big news! There's a new AGD cross-compiler in town, this time for the forthcoming ZX Spectrum Next although it will produce games for machines which support the Timex 8x1 attribute mode. This is a command-line compiler which takes a program written in AGD script and turns it into a complete game assembly language listing.
AGD V0.1 runs under Windows 32 but the C source code is included should you wish to run this version with another operating system.
Head to the downloads page for more information!
