Emu7800 v1.0 is released. Emu7800 is an Atari 7800 emulator implemented using Microsoft's .NET platform. Most VCS (2600) and ProSystem (7800) titles work well, with 2600 support featuring authentic HMOVE emulation, per Andrew Tower's paper "A Small Opus on the TIA." The stars in Cosmic Ark appear without emulation cheats! Emu7800 runs on Windows 2000 and higher systems. Performance is excellent on recent hardware.
