Po paromiesięcznej przerwie opublikowano nową wersję multiemulatora DSP pozwalającego pobawić się maszynkami arcade i ośmiobitowcami - CPC, ZX Spectrum (z bardzo fajnie rozwiązanym podglądem plików), a także Colecovision, Nintendo 8 i CGB/GB. Dość nietypowy projekt na pierwszy rzut oka, jednak jeśli przyjrzymy się zagadnieniu od strony technicznej widać, że wszystko opiera się na podobnych rozwiązaniach.
