This program emulates a Sinclair ZX Spectrum 48-kbyte z80-based computer on
any Amiga computer. Binary only, Author: Peter McGavin
v1.7: Sped up OUT instructions. (Sound is noticeably higher pitched.) Fixed bug
where key-up event was lost after SAVE-ing to disk. Applied dozens of small code
optimisations suggested by Mark Knibbs, mainly in the Z80 emulator and in the
display routines. Input from IO port 255 (or any other port than the standard
ones) now sometimes returns 0 or a video attribute from the current display, to
better emulate a real Spectrum. It used to always return 255. Fixed bug which
caused emulator task to go into an unbreakable loop when certain multi-byte
instructions crossed the 32767/32768 address boundary. Use ASL file-requester if
available (requires OS 2.x and up for this). Moved requesters to custom screen.
Added menu options to switch the titlebar on and off, set the task priority and
control the sound volume. Enabled "Save to Audio", even though it doesn't seem
to work properly. Window is now a title-less backdrop window that is the width
of the screen. The close-box feature has gone. Use menus or ESC to quit instead.
Load snapshot from CLI command-line or project icon. Distribute Spectrum.rom
with emulator.
