- Games crashing - Der Langrisser ==Overview==The ZSNES developers focused on speed over [[Emulation accuracy|accuracy]], so a hefty amount of games have bugs (freezes after 2-3 hoursand some just crash outright), Super Mario RPG . The current version (freezes in many different points of the gamev1.51), Star Ocean created more problems than it fixed and many other games have freezing and crashing issuesproblems still remain:[[File:Kirby3-forest.gif|frame|SNES Pseudo Hi-Res translucency on ''new'' graphics engine]]* Compatibility is lower than modern emulators due to low accuracy to real SNES system.

- Bad sound emulation - A ton * 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 just sound terrible on [[File:Kirby3-forest.gif|frame|SNES Pseudo Hi-Res translucency]]ZSNES, Earthworm Jim 2 has no sound effectshave freezing and crashing issues.

- Super FX not clocked correctly - Star Fox runs twice as fast as it should* 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.

- Transparency - Kirby Dreamland 3, Mecarobot Golf[[File: Old zsnes snow gui.jpg|left|thumb|300px|Despite being outclassed by many more accurate ''and secure'' emulators, Jurassic Park and any game that uses Pseudo Hi-Res translucency wont display correctlysome held on to Zsnes for its iconic user interface.]]

In 2011 byuu released [http://byuu.org/bzsnes/ bZSNES] * SA- a modification of his bsnes that includes the optional inaccuracies of ZSNES and a similar GUI. This version of bsnes 1 isn't emulated correctly, so Kirby Super Star can accurately emulate sometimes spawn different sprites than the ROM hacks made specifically for ZSNES, which means the only thing ZSNES had going for it can now be played on a much more accurate emulatorsupposed one.

<These are just a few problems, there are a few more listed [https://floating.muncher.se/byuu/accuracy/ here] and [http://sourceforge.net/p /zsnes/bugs/ here]. It is recommended to use [[Snes9x]], [[bsnes]] or [[ares]] instead.   {| class="de1mw-collapsible wikitable">style="width: 100%;"! colspan=2 width="250"|Review|-| '''PROS''' ||* Individual layers can be switched on and off, allowing to take screenshots without sprites or with sprites only, among other possibilities.* Can pause emulation at any time* You can access and navigate all menus with the keyboard only; you are not forced to waste time looking for the mouse with your hand and for its cursor on the screen.* Excellent netplay connectivity between 2 players* In-game chat that doesn't require switching focus between 2 windows* The host's save file is immediately shared with the client, so you don't need to upload it elsewhere first* In case of desynchronization, the host can make save states and load them for both players to resynchronize* 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 dial-up user and someone on DSL* You can switch between windowed mode and full screen with ease.* Using version 1.36, games pretty much do not desynchronize period* Still has some big communities and dedicated servers like [http://emu.z-net.us Z-Net]|-| '''CONS''' ||* 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 desynchronize unless you specifically use ZSNES 1.36 or 1.337* Interface might be unappealing to some people|} ==ROM hacks==Many ROM hacks and ROM hacking tools were made using ZSNES as a testing platform because of its popularity.
