Sinclair ZX Spectrum emulator from the 80s.
Spectral is an experimental emulator that I have been randomly assembling since the pandemic days, inspired by my old fZX32 emulator. Accuracy and performance are long-term goals, but the primary focus is just having fun with this thing. Hardcore ZX users will find little value in this emulator right now, but I hope newbies may find its ease of use somehow appealing to try. That being said, Spectral has a very compatible TAP/TZX loader and some other interesting features that provide me some fun in these days. Code is highly experimental and prone to change in the future. I will keep altering/breaking things randomly for good sake.
