ZSNES OR SNES9X WINDOWS

It currently runs on Windows, Linux, FreeBSD, and DOS. On Apthe ZSNES project was GPL'ed and its source released to the public. It continues to be popular among collectors and retro gamers, with new homebrew games and Nintendo's emulated rereleases, such as on the Virtual Console, the Super NES Classic Edition, and Nintendo Switch Online. ZSNES is a Super Nintendo emulator programmed by zsKnight and Demo. Overlapping the NES's 61.9 million unit sales, the SNES remained popular well into the 32-bit era, with 49.1 million units sold worldwide by the time it was discontinued in 2003. The SNES was a global success, becoming the best-selling console of the 16-bit era after launching relatively late and facing intense competition from Sega's Genesis console in North America and Europe. As this emulator focuses on speed, its accuracy is low compared to other emulators. Unfortunately, it has not been updated since 2007 and is now considered obsolete. The system was designed to accommodate the ongoing development of a variety of enhancement chips integrated in game cartridges to be competitive into the next generation. ZSNES was one of the first Super Nintendo emulators that could play a wide range of games at good speeds, which once made it one of the most popular Super Nintendo emulators. The console introduced advanced graphics and sound capabilities compared with other systems at the time. The SNES is Nintendo's second programmable home console, following the Nintendo Entertainment System (NES). Although each version is essentially the same, several forms of regional lockout prevent the different cartridges from being compatible with one another. In Japan, the system is called the Super Famicom (SFC). Most Konami games tend to desynch unless you specifically use ZSNES 1.36 or 1.The Super Nintendo Entertainment System (SNES), 1991 in North America, 1992 in Europe and Australasia (Oceania), and 1993 in South America.Sometimes it outright refuses to connect 2 people via netplay through UDP for unknown reasons.

It's 2P ONLY, with no multiplayer version foreseeable in the near future.Using version 1.36 games pretty much do not desync period.You can switch between Windowed mode and Fullscreen with ease.It works just as well with between a dialup user and someone on DSL.You can change emulator latency on the fly to compensate for choppiness at the expense of slight input lag.In case of desynch, host can make savestates and load them for both players to resynch.The host's save file is immediately shared with the client, so you don't need to upload it elsewhere first.

ZSNES OR SNES9X WINDOWS

In-game chat that doesn't require switching focus between 2 windows.

Excellent connectivity between 2 players (ONLY).

It uses the exact same interface that ZSNES uses. ZMZ is a program that utilises libretro versions of Snes9x and the Next variant, as well as the Bsnes cores, much like RetroArch. It however only has moderate compatibility with ROM hacks made specifically for ZSNES. This was done as an April Fools day joke. In 2011, byuu released bZSNES - a modification of his bsnes that includes the optional inaccuracies of ZSNES and a similar GUI. However, because of the inaccuracies of the emulator, these tools and hacks are broken on other, more accurate emulators and real hardware. Many ROM hacks and ROM hacking tools were made using ZSNES as a testing platform because of its popularity. It is recommended to use Snes9x or RetroArch with the bsnes core(s) instead. These are just a few problems, there are a few more listed here, and here. To get them to display properly in 1.51, you have to press 8 to switch to the old graphics engine, or just use an older version.

Transparency - Kirby's Dream Land 3, Mecarobot Golf, Jurassic Park and any game that uses pseudo hi-res translucency won't display correctly in the default graphics engine.

For example, Super FX for example is not clocked correctly - Star Fox runs twice as fast as it should.

Many of the co-processors, which are actually on the cartridges, are emulated in extremely strange ways.

Bad sound emulation - A ton of games sound terrible on ZSNES Earthworm Jim 2 has missing sound effects, some sound effects are missing or sound like short beeping noises, which is not correct behavior.

Snes9x vs Zsnes S-SMP emulation accuracies

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.

Compatibility is lower than any modern emulator due to low accuracy to real SNES system.

SNES Pseudo Hi-Res translucency (Why you shouldn't use ZSNES!)

The current 1.51 created more problems than it fixed and many problems still remain: The ZSNES developers focused on speed over accuracy, so a hefty amount of games have bugs (and some just plain crash).
