zsnes game snapshots

invictius · Post by **invictius** » Sun Oct 30, 2005 12:29 pm

Just exported a few hundred snapshots of a game (took hours) into bmp format, and realised they looked CRAPPY compared to using that hq2i mode in zsnes. Is there any way to clean them up in paintshop/photoshop, similar to the way zsnes does it, or any way that will make them not look like crapphy 256x256 snapshots? I really don't want to spend 6 hours of monotonous button pressing again...

We would suggest using the printscreen key instead.

Or write your own HQ?x filter application program.

BMP format??? Wha?

You do realize you can take the snapshots in PNG format....

Not to say I could implement it myself, but it would be a nice feature to add filtering to the screenshots (to make it easier for some people)... I mean.. someone did spend time to add a GUI filter feature, yes? I personally don't care for the feature though since there is an alternative (a slower method if you want to take multiple snapshots)

Why? Especially when MaxSt has such software available on his website.

Photoshop is meant to have anti-aliasing, but it just doesn't show up :/. Nach, which utility are you referring to? I can't find it on his site. Aerdan, since I had to use keys to disable sprites and backgrounds, using print screen would have been waaaay too much hassle, especialy considering you can only copy one image at a time. I tried to use fraps in the WIP, but it just didn't work. Deathlike2, I was obsessive about quality, and I thought PNG's were only 256 colours. Plus, the bmp's were only 100k anyway.

...at the bottom, there is an exe.

PNG screenshots from ZSNES are 24-bit (same as the bitmap, so no info is lost), and would be about a 1/5 of the size as they are compressed.

http://en.wikipedia.org/wiki/PNG

PNG (Portable Network Graphics) is a lossless bitmap image format.

PNG gives a much wider range of color depths than GIF (truecolor compared to 256-color)

Truecolor = 24-bit or greater (32-bit)

http://en.wikipedia.org/wiki/Lossless_data_compression

Lossless data compression is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data.

Hmm.. 100kb of BMPs (ew) or an average of around 15kb of PNGs... (my smallest is 4kb, biggest is 27kb)

You decide..

Thanks guys for that link. I thought it would be in "other". I had to rename ALL 500 files to omit the rom name, and make up a batchhttp://www.eftel.com/~marksmith/bat.bat

I typed it by hand, used find and replace where i could, could there have been an easier way to do it? Also, why isn't 4x implemented in zsnes?

HQ4X?

It's already implemented..but you have to use a resolution 1280x960 or greater to take advantage of it in ZSNES (meaning you need a decently powerful system)

convert.bat :

Code: Select all

mkdir output
for %%a in (*.bmp) do hq2x.exe %%a output\%%a

Would a p4 3ghz, geforce 6800, 2 gig ram be enough? Because that's all i have

EDIT: Anyways, the higher resolution you use, i guess the more need there is for HQX. Since 1280x960 is double 640, and 2X is available in 640...

Dude, my freakin' 1.2GHz Duron with GeForce FX 5200 and 768MB RAM can handle it just fine. :p

Funny, because my AMD64 3000+ can't handle it just fine. Why is it that the HQxx filters slow the emulation down to a crawl on some systems even though the computer specs are more than enough to handle HQxx?

Depends on the game being played, and other settings. Playing hq4x with vsync, -6 switch, or 0 frameskip will cause slowdowns with certain games on just about any system. Triple Buffering + Auto frameskip works better here.

Note that hq4x is a win port exclusivity as of now.

HyperSnap DX can take screenshots continuously IIRC.
