👻 Spectral

[Jimmy Gallagher]

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.

Nice work!

Does it support booting from alternative .ROM/.BIN images? Many "updated" versions of Sinclair BASIC have been made over the years, such as OpenSE.

@r-lyeh:

Yes and no. Spectral will reset the roms and state after every drag 'n drop. right now, you can drop basic roms or interface I roms into the emulator and give them a try, it will work. but if you drop a second file after that, Spectral will reset the roms again and will use the default stuff

Have a look at the new game that just got released in the CP/M section for the +3... It should work with this.

They link to a DSK file to mount it.

Are you talking about Tale of Ancient Land? I couldn't run it on Fuse, EightyOne, Klive IDE Project, Speccy and Spectral.
