Turbo Rascal SE (TRSE) v0.17 is out. It's a complete suite (IDE, compiler, programming language, image sprite level resource editor) intended for developing games/demos for 8 / 16-bit line of computers, with a focus on the MOS 6502, the Motorola 68000, the (GB)Z80 and the 8086. TRSE supports application development for the C64, C128, VIC-20, PLUS4, NES, Gameboy, PET, ZX Spectrum, TIKI 100, Amstrad CPC, Atari 2600, 8086AT, Amiga 500 and the Atari ST 520 (complete list here). With the benefits of a modern IDE (error messages, code completion, syntax highlighting etc) and a bunch of fast built-in tools, it has never been easier to program for your favorite obsolete system !
You can join the TRSE group on Facebook.
The video below is a gorgeous Amstrad CPC demo programmed with TRSE : Morketid.
