[ZX] ZXIAN v18 2/01/2023

ZXIAN v18 2/01/2024

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

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.
