Changes

'''ZSNES''' is a [[Super_Nintendo_emulators|Super Famicom (SNES)]] emulator written in x86 assembly. It was originally made in 1997, and has not been updated since 2007.

The ZSNES developers focused on speed over [[Emulation Accuracy|accuracy]], so a hefty amount of games have bugs (and some just plain crash). The current version (v1.51 ) created more problems than it fixed and many problems still remain:

*Compatibility is lower than modern emulators due to low accuracy to real SNES system.*Games crashing: Der Langrisser (freezes after 2-3 hours), Super Mario RPG (freezes in many different points of the game), Star Ocean and many other games have freezing and crashing issues.*Bad sound emulation: Many games sound inaccurate on ZSNES. ZSNES's audio timer isn't floating point so there are timing artifacts in the music. ZSNES doesn't emulate release values of ADSR so held notes will sound poor.*Many of the co-processors, which are actually on the game cartridges, are emulated in strange ways. For example, Super FX is not clocked correctly; Star Fox runs twice as fast as it should.*Transparency: Kirby Dreamland 3, Mecarobot Golf, Jurassic Park and other games that use pseudo hi-res translucency won't display correctly in the default graphics engine in v1.51. To get them to display properly in v1.51, one must press 8 to switch to the old graphics engine.*x86 Code Exploitcode exploit: With specially made hacks and homebrew ROMs, it is possible for them to break out of ZSNES itself and [https://www.youtube.com/watch?v=Q3SOYneC7mU execute native code on the host computer.] *While older versions of ZSNES still have one of the better netplay systems among emulators, netplay was removed in v1.50.

These are just a few problems, there are a few more listed [http://web.archive.org/web/20120217115713/http://byuu.org/bsnes/accuracy here], and [http://sourceforge.net/p/zsnes/bugs/ here].

*Excellent netplay connectivity between 2 players*In-game chat that doesn't require switching focus between 2 windows*Can pause emulation at any time*The host's save file is immediately shared with the client, so you don't need to upload it elsewhere first*In case of desynchdesync, host can make savestates save states and load them for both players to resynchresync*You can swap controllers at any time*You can change emulator latency on the fly to compensate for choppiness at the expense of slight input lag*It works just as well with between a dialup dial-up user and someone on DSL*You can switch between Windowed windowed mode and Fullscreen full screen with ease.*Using version 1.36 , games pretty much do not desync period

*Netplay is 2P ONLY, with no multiplayer version foreseeable in the near future.*Both players need their port forwarded to connect over UDP for netplay, and TCP can be quite choppy*Most Konami games tend to desynch desync unless you specifically use ZSNES 1.36 or 1.337*Interface might be unappealing to some people
