CSpect
What it is
CSpect is a free ZX Spectrum Next emulator for Windows, macOS, and Linux, intended mainly as a development tool. It can also run games and the full ZXNextOS environment. The maker describes it as an emulator, assembler, and debugger, and the release notes list ULA overlay support that provides access to an extra 24 kB of RAM. The debugger can be resized, with a -dscale command-line option for larger text. CSpect supports z88dk map files directly, and its plugin system includes a symbol interface, a Pasta/80 symbol loader, and a z88dk map-file loader. The iCSpect interface includes AddSymbol() and HexToInt64(string). Linux shell scripts are included in the release archive; ZXOS.BAT is described as a way to download and install the ZX Spectrum Next SD card image. The maker says there is no support or warranty and recommends using the software at the user’s discretion. Users are advised to assume updates will not be available. Password-protected beta builds are a perk for Builder-level Patreons, and redistribution is not permitted.
