zxian is a ZX Spectrum emulator written in C, using SDL2 for graphics, input/output, and audio. As with my other projects, the source is available for download. I built it with Visual Studio Community 2019 (with C++ core features installed). Changes: v10 - fixed an interrupt bug which allowed reentrancy; this fixes games such as Zynaps 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 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 Download: http://sebastianmihai.com/downloads/zxian/v10/zxian_v10.zip http://sebastianmihai.com/ -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 114.136.201.148 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/Emulator/M.1684735758.A.A66.html
