 Setting up your development platform for the ZX Spectrum is quite easy, first get the following tools:
-* Assembler: SJASMPLUS -This assembler has nice macros for creating Binaries and SNA snapshot files out of the box. You can download it at https://sourceforge.net/projects/sjasmplus/

 * Pasmo - for the .TAP create. Available at : http://pasmo.speccy.org
 * Emulator(s): I Found [https://www.zophar.net/sinclair/zx-spin.html ZX Sping], [https://sourceforge.net/projects/fuse-emulator/ FUSE], [https://sourceforge.net/projects/unrealspeccyp/ UnrealSpeccy] and [https://www.aptanet.org/eightyone/ EightyOne] to work best for my usecase.
