SpecIde (2025/06/21) is released. SpecIde is (yet another) ZX Spectrum (and, partially, Amstrad CPC) emulator. Currently, the ZX Spectrum emulation is quite accurate. The Amstrad CPC emulation is still a work in progress, but it is mostly enough for playing most games.

Features:
Emulation of ZX Spectrum 48K (Issue 2/3), 128K, +2, +2A and +3.
Emulation of Amstrad CPC 464/664/6128. No support for Plus models yet!
FDC765 disk drive emulation. (Scan commands are missing yet)
Emulation of Spanish 128K, +2, +2A and +3.
Emulation of Pentagon timings (but no BetaDisk yet! Sorry for that!)
PSG (AY-3-8912/YM-2149) sound emulation.
Turbosound emulation. Supports two and four PSG modes.
Covox/Soundrive emulation.
Loading of tapes via .tap and .tzx tape images, and .csw files.
