- Structures to work easily with structured data in memory (
STRUCTpseudo-op) - Virtual device mode for common machines: ZX 128, ZX Next, … (pseudo op
DEVICE) - ZX Spectrum specific directives and pseudo ops (SAVESNA, SAVETAP, SAVEHOB, INCHOB, INCTRD…)

SAVENEX) - Correctness is assured by Cirrus-CI with 256+ automated tests (that's also 256+ examples of usage!)
- Fake instructions as
LD HL,DE(LD H,D:LD L,E) and more - Code inlining through colon (
