Software Update: ZSNES 1.40

ZSNES is a small program that includes a Super Nintendo Entertainment System Linux† DOS or Windows can emulate. The software can mimic the sound hardware, graphics engine, and special SNES hardware such as the SuperFX chip, among others. The developers of ZSNES released version 1.40 today. This release has many changes and is available from this page to bring in. Below you can read which changes have been made:

• Many new video features, including (but not limited to): HQ2X, HQ3X and HQ4X graphic filters, support for hi-res and D modes in 32bpp windowed mode (now default), new aspect ratio code for scaling, and the KitchenSync (usable only through the command line). [MaxSt, pagefault, Darkfalz]
• Fixes for video code errors, such as those that occur when alt-tabbing in fullscreen, MMX interpolation fixes, and blitter fixes. [pagefault, zsKnight]
• Snapshots are now numbered and use the full ROM file name. [Nach]
• Renamed Windows version to Win32. [pagefault]
• Win32 port can now also be compiled with MinGW (but we won’t support it until the next release). [Nach]

All Ports:

• Added multiple timing tweaks, fixed various emulation bugs, and many other technical updates, including (but not limited to): SPC core updates (with improved sound decoding), safer memory allocation in certain areas, HIRQ and VIRQ fixes, color add/sub and color bleeding fixes, HDMA improvements, sprite priority and flickering fixes. Many more games work . [pagefault, _Demo_, Nach, TRAC, Overload, theoddone33]
• Overhauled a lot of code, such as checksum calculation and mirroring code. Overhauled and added much better EHi/Hi/Lo ROM code, improved reset vector, changed much hard coding to variables. Fixed more SRAM bugs than can be counted. Made optimizations to complex loading functions, syntax, memory init (Thanks kode54), execution, and initialization code. Also greatly improved PAL/NTSC detection. Also now has much better chip detection and gives more informative chip names. More games which never loaded before now load properly, such as Dai Kaiju Monogatari 2 now loads and plays great without the Dejap patch. [Nach]
• Cleaned up, overhauled, removed, and ported a lot of code (asm to C). [pagefault, MKendora, Nach]
• Overhauled IO latch behavior, added proper latching behavior and other latch fixes (such as proper latching of bit 7 on $4201), and added proper behavior of RDIO regs. [pagefault]
• Removed many, many hacks. [Nach, pagefault]
• There have been some modifications and reorganizations of the GUI, including new path setup and chip configuration windows and a reorganization of the Game Key window. [pagefault, Nach]
• Updates to the video code, with enhancements of triple buffering, better input support in the video dialog, and other general video code updates and bug fixes, such as a fix for the 60hz mode. [pagefault, MaxSt]
• New extra options are now available in various locations, like the “GUI burning effect”, new commandline options, a new quick key to control players 1/2 with 3/4, and smaller message text. Some obsolete ones have been removed. [pagefault]
• Some changes in the Input configuaration: Hitting “Set Keys” is now prevented if controller is set to “None”. Also, if no controller is selected, the settings of the individual keys are now locked. [Nach]
• Updated default configuration, in general. For example, stereo sound is now enabled by default at 32khz, with gaussian interpolation. [pagefault]
• Signed saturation fix for gaussian interpolation (Thanks kode54). [pagefault]

• Added support for many more ROM extensions. [Nach]
• ROM info now dumped to rominfo.txt on game load. [Nach]
• Added more information lines on ROM load, such as CRC32, video, and bank information. [pagefault, Nach]
