First ZSNES Release In ~2.5 Years

Anonymous Coward writes "The best SNES emulator, and the only GPL one -- ZSNES -- has had the first release in almost two and a half years! Looks like those smart coders reverse engineered quite a few new special co-processors for this release as well."

Excellent!

Yesterday I tested zsnes first time on my linux laptop and was blown away - excellent emulator!

And now I read about a new release - even better!

Re:Excellent!

[Elektroschock]

I really wonder why emulators such as dosbox and Zdnes are not better integrated in your desktop environment. I mean KcontrolCenter configuration modules, I mean a "just run" environment, where the whole emulator is nidden as a background process. The main advantage of gaming consoles is that you just insert the disk7cardrige and start to play.

Re:Excellent!

[stratjakt]

Oh yeah, well I'm not a fluxbox user, I want to double click a ROM file and execute it.

Not based on extension, I want a real filesystem with attributes, and it executes based on the "SNES" attribute.

There's no integration needed, just a good filesystem and good desktop environment.

Replace "ROM" with "digital photo" and "emulator" with "GIMP" if you want.

Actually, there have been work in progress releases all along. This is the first non-"beta" release in two years.

See you in WoW, pagefault. :D!

2.5 years.. gad

[cente]

Gee, I thought snes emulation was perfect already! What a long time to put something out though... Everyone get out your "archived" snes games again!

Re:2.5 years.. gad

[BradleyUffner]

It hasn't really been 2.5 years. There have been unofficial builds released every few months, they refer to them as "WIPs" or Work In Progres. The WIPs are awesome, each one fixed a bunch of bugs, and was rock stable.

Best?

"The best SNES emulator"

Ho boy, flamewar. Personally I think SNES9x has been the best/most reliable, and has been updated far more frequently. And before people say "it's Windows only", it's not. I have a port sitting on my Mac OS X dock right now. Don't know if there's a Linux port.

Re:Best?

[Horse Rotorvator JAD]

I'll throw in a second vote for snes9x. As can be seen on their download page http://www.snes9x.com/downloads.asp they have ported snes9x to; Solaris, OpenBSD, Irix, N64, FreeBSD, AmigaOS, BeOS, RiscOS, SunOS, MS-DOS, HP-UX, MacOS, Linux and Windows.

It has a very easy to use and intuitive interface with all the options that one would expect from an emulator. It is stable and has played every single ROM I've thrown at it without a single problem. Whenever I set up a new USB thumbdrive with all my essential software, snes9x always goes on there.

Re:Best?

[stratjakt]

No need for a flamewar, the two teams put aside the moronic infighting years ago and have largely collaborated.

Back when, ZSNES was fast, because it was written in ASM. SNES9x was more compatable, because it was easier to tweak. And there was much boasting and bickering and it was basically an e-Penis contest between the two emus.

Eventually they came together.

Now, SNES9x got all its ASM code straight from ZSNES, ZSNES got its compatability and other features from SNES9x.

Both projects would suck without getting together. SNES9x would still be slow and chunky, ZSNES would be missing a lot of compatability and features.

Both are pretty good examples of what OSS projects can achieve when the authors put egos aside and focus on the end result.

Who cares ?

What you slashdot folks don't realize is that the maintainers of the various emulators are all sleeping in bed with each other. Maria Kendora* (snes9x), Nach, kode54, pagefault, _Demo_(zsnes) all work together to understand more about the snes because often the documentation and knowledge they have is so little about whatever odd chips were used in that one obscure game. They'll even resort to reading half-assed patent applications in hopes of sheding some light.

You can even join #zsnes on Freenode, and watch the developement of zsnes right in front of your own eyes. The developement of one OSS emulator is the developement of another. Especially with the tight knit community of coders/hackers.

You'll never see zsnes ports for most of those systems because large chunks of zsnes are written in x86 assembly. To me that's a plus, because its hard for a higher-level language to beat assembly in terms of speed. zsnes is much faster than Snes9x, and therefore I can run it on older systems. Its true that it does suck if you don't run an x86-based box, but that doesn't make it inferior, just different.

Nice and all...

SNES9X

[acidblood]

I was always partial to SNES9X for some reason (perhaps it's the fact that they don't waste their time coding everything in assembly, as nobody should), and it's also open source. Whether it is GPL'd or not is just flamewar fodder -- most certainly the submitter's intention.

Re:SNES9X

[Yosho]

You have to keep in mind that back when ZSNES was first being developed, computers weren't fast enough to emulate a SNES properly. I recall first using ZSNES on a Pentium 2, 300 MHz; not top-of-the-line, but a pretty good computer for the time. As far as I can recall, there weren't any SNES emulators that would run games at full speed, but ZSNES came pretty close; SNES 9x was more accurate, but also considerably slower unless most of the features were disabled.

Re:SNES9X

[DarkHelmet]

One of the features in 1.40 is listed as:

• - Cleaned up, overhauled, removed, and ported a lot of code (asm to C). [pagefault, MKendora, Nach]

I think they're addressing that shortcoming.

Re:SNES9X

[moosesocks]

ZSNES ran at about 90% frame rate on my Pentium-100. I never even noticed the missing 10% until I actually checked the frame-counter -- it was still better than playing a 'real' SNES.

It's a real testament to their coding skills.

Re:SNES9X

[acidblood]

Regardless, I can assure you that it'd be just as fast if about 20% not 100% of the code were written in C. I'm not familiar with emulators, so maybe those 20% are actually 30 or 40%, but never 100%. I assert this as a speed freak and optimized assembly coder (did a couple of cores for distributed.net). It's just a complete waste of time to write, say, GUI code and file handling in assembly.

Actually, I'd go so far as to hypothesize that ZSNES would be faster if it were written in C/C++ with careful assembly optimization only where needed: the higher productivity associated with a high-level language would mean more time to optimize the parts of the code where speed really matters.

Geez

[AvantLegion]

I just finished installing the old version!

Reccomendation

[labratuk]

For anyone wanting to play SNES games I highly reccomend looking in your kernel documentation about how to hook up your SNES controller to work with the gamecon driver. Only takes about 10 minutes.

Re:Reccomendation

[Anonymous Coward]

Or if you have the cash to burn, buy:

1. A SNES to USB adapter.

2. A premodded USB SNES controller (basically a SNES controller that's been gutted and replaced with new hardware to make it a USB controller).

Re:A little OT, but...

[Kyouryuu]

The game's manufacturer, Koei, still makes regular releases of their Romance of Three Kingdoms and Dynasty Warriors series. They are still known for their tactical strategy games. Aerobiz was a very unique game since it dealt with corporate strategy in a way very different from more comtemporary games of that ilk (SimCity, etc) but I haven't heard about any plans to bring it back.

For the uninitiated, Aerobiz and its sequel Aerobiz Supersonic were two games released on the SNES and Genesis. The aim of each was to become the most profitable airline in the industry. You could play the game at different points in time - the dawn of airplanes for business commutes all the way to Concorde-like supersonics. To win, you would have to oversee buying various real-life planes (Boeing, Lockheed, Airbus, etc), slots at worldly airports, and compete directly with three other companies who were also vying for the same assets. You would try to have a hub in each continent and grow the airline from there with large transoceanic flights. If a particular route was not profitable, you could alter its ticket prices, switch to a smaller plane, or other various options. The game actually had a board of directors you could meet with for advice (similar to SimCity's "Advisors"). Additionally, you could diversify your business by purchasing hotels or golf courses in respective cities. Various events, like the Summer Olympics and disasters, like fuel crises, war or worker strikes, would also influence your growing business. One of the features that made Aerobiz unique was that it was multiplayer. Although you had the option of making any number of them AI, the three other corporations could be other players. Granted, it's rather slow-paced and geeky, but it's arguably the closest thing there ever was to a competitive simulation game.
