About

CSpect is a free ZX Spectrum Next emulator for Windows, macOS, and Linux, intended mainly as a development tool. The maker also describes it as an assembler and debugger. It can run games and the full ZXNextOS environment. Release notes describe ULA overlay support that provides an extra 24 kB of RAM, a resizable debugger, and a -dscale command-line option for larger debugger text. CSpect supports z88dk map files directly. The product page lists a plugin system with a symbol interface, a Pasta/80 symbol loader, and a z88dk map-file loader. Its iCSpect interface includes AddSymbol() and HexToInt64(string). Linux shell scripts are included in the release archive. For the full machine environment, the release notes describe ZXOS.BAT as a way to download and install the ZX Spectrum Next SD card image. The maker says there is no support or warranty and advises users to assume updates will not arrive. Password-protected Patreon beta builds are a perk for Builder-level Patreons. Redistribution is not permitted; the maker directs users to the product page.
