[ZX] ZXIAN v18 2/01/2023

ZXIAN v18 2/01/2024

• added zxianui, a friendlier, UI-based zxian starter

ZXIAN 0.35 26/03/2026

• added support for CRT-like blur and black-and-white displays

ZXIAN 0.34 12/03/2026

ZXIAN od pewnego czasu ma prościutki interfejs ułatwiający odpalenie emulacji ZX Spectrum. Przydałaby się jeszcze obsługa .tzx i spakowanych archiwów.

• users can now choose to autohide UIs (poke, tape) when not hovered. UIs now display within ZX Spectrum's border, to save vertical space. UIs now look clearer and support holding down mouse button

ZXIAN 0.33 24/01/2026

• users can now begin tape loading much sooner after emulator start. Users now have the option to autoplay tape at emulator start. Save states now also store current tape block, improving multiloads

ZXIAN 0.32 15/01/2026

• improved timing accuracy by introducing memory/IO contention. Fixed incorrect (too slow) timing of CB prefix opcodes. The above changes improved gameplay of games such as Manic Miner. The above changes improved audio fidelity of games such as Skool Daze

ZXIAN 0.31 02/01/2026

• fixed a long-standing sound sampling bug due to a rounding error. Increased the number of audio oversamples. These changes improved sound quality and reduced resyncs. Improved CPU timing and how it deals with tstate overruns. This fixes games such as Mask III. Added a history selector (recently-loaded files) to the UI

ZXIAN 0.30 03/11/2026

• added support for loading and saving Z80 snapshots; Fixed a bug whereby IM0 did not behave like IM1

ZXIAN 0.29 27/10/2025

• added support for game controllers, with re-mapping and autofire. Rewrote rewind functionality to allow for multiple rewinds

ZXIAN 0.28 26/04/2025

• added support for sound volume control

ZXIAN 0.26 20/04/2025

• added support for emulation rewinding

ZXIAN 0.26 27/03/2025

• added a button which plays a single tape block, for multi-load games. Removed clicking noises heard during tape loading

ZXIAN 0.25 28/02/2025

• fixed a bug which sometimes deteriorated sound quality at high sample rates. Improved sound quality via oversampling. Screenshots now no longer include UIs elements (e.g. poke UI)

ZXIAN 0.24 28/02/2025

• corrected R register behaviour (7bit counter instead of 8bit). This fixes games such as Robin of the Wood, Ping Pong, Sanxion

ZXIAN 0.23 2/02/2025

• fixed a border rendering bug after fast tape loading finishes. Fixed a TAP loading bug concerning custom-length header blocks. This fixes games such as Lemmings

ZXIAN v0.22 13/01/2025

• added support for saving SNA snapshots

ZXIAN v0.21 7/01/2025

• added support for more options to the UI. Fixed a border rendering bug in fullscreen display modes. Fixed minor scanlines effect bugs

ZXIAN v0.20 21/11/2024

Versions 1 through 19 are compiled exclusively to 32bit.
Versions 20 and later are compiled exclusively to 64bit.

• v20 - first 64bit version

• v19 - optimizations: reduced host CPU usage by 75%-90% of previous version

ZXIAN v17 6/11/2023

• added support for taking screenshots

ZXIAN v16 31/10/2023

• added support for CRT scanlines effect. Fixed a slowdown issue when using accelerated renderer. Removed an overly eager optimization which impacted CPU-screen sync - this fixes games where graphics are updated multiple times per frame

ZXIAN v15 12/10/2023

• added fullscreen support

ZXIAN v14 07/10/2023

• sound improvements via variable sync. This fixes sustained tones (such as the BEEP command in BASIC)

ZXIAN v13 26/09/2023

• optimizations: reduced host CPU usage by 85%

ZXIAN v12 23/06/2023

• CPU microcode fix: R register behaviour  this unfreezes some games which rely on R for timing, like Defender of the Crown
• CPU microcode fix: DD/FD prefix opcodes fall-through to unprefixed cleaner application shutdown

ZXIAN v11 09/06/2023

• added support for saving and loading state
• added a UI which allows memory modification (pokes)

ZXIAN v.10 18/05/2023

• v10 - fixed an interrupt bug which allowed reentrancy; this fixes games such as Zynaps

ZXIAN v.9 13/05/2023

• v9 - fixed an overflow bug which deteriorated sound after 20 minutes
• v8 - tape UI improvements: current block size and progress; sound improvements: configurability and parameter tweaks
• v7 - added support for frame skipping. Improved sound quality and configurability

ZXIAN v.6 13/02/2023

• v6 - significantly improved audio quality. Added support for TAP tape images
• v5 - video frame duration can now be specified in milliseconds. Rewrote the "read key status" code to fix a bug, which fixes games such as Manic Miner
• v4 - support for "floating bus", whereby data read by ULA can "leak" into hardware ports that are not wired, such as 0xFF. Some games rely on this for timing, instead of an interrupt handler. This fixes games such as Cobra and Arkanoid
• v3 - improved game compatibility by supplying a well-known value for the LSB during IM2 handler lookup; previous behaviour can be attained through a switch. This fixes games such as Dizzy 7
• v2 - fixed an SNA loading bug caused by incorrect IFF2 initialization; it was causing some games to soft reset, and some to have corrupted graphics
• v1 - initial release

Dizzy II z małym helpem do ZXIAN, przyda się zdecydowanie.
