ZSNES v1.51, with the SPC7110 v5
Okay, at long last, I think I finally completed all the SPC7110 programming and tweaking (famous last words). If you find any issues, let me know, and I´ll try to fix it (sigh).
Windows:
http://zsnes.sourceforge.net/zsnesw-spc7110-5.zip
DOS:
http://zsnes.sourceforge.net/zsnes-spc7110-5.zip
Changes:
_Demo_ and I optimized the code even more, to the extent that we don´t think there´s anything else significant we can do.
Fixed a bug with save states/rewind that Deathlike found.
Removed the gfx packs stuff from the GUI and config file.
Added to the config file an option to turn off the graphics cache.
The cache isn´t used if there´s not enough free memory, but you can play SPC7110 games anyway.
Cleanup.
Post results of speeds with the cache on and off (changing the setting requires ZSNES to be restarted). I´d appreciate if people with sub 1 GHz machines can post some FPS and CPU info with and without cache.
Todo:
Post source changes for people who want them.
Coordinate with some translation teams to get the 4 SPC7110 games translated. If you need a special build of ZSNES for something, or some info which I can provide, let me know.
Party?

ZSNES v1.51, with the SPC7110 v4
Okay, _Demo_ pointed out some relics of neviksti´s code still in our optimized version. I rewrote some of the tightest loops to use 64 less bytes of memory, and only loop 25% of the amount of loops it was currently doing.
http://zsnes.sourceforge.net/zsnesw-spc7110-4.zip
Let me know if I broke anything. If you also were getting a slow down on initial load in the previous build, that should be cut down now.
Test with the cache deleted, and let me know how it works.
---------------------------------------------------------------------------------------------
ZSNES v1.51, with the SPC7110 v3
Okay, anomie and I rewrote pretty much all of neviksti´s code and seriously optimized it like nuts. We still have a little bit more that we can optimize (and hopefully will), but we´re MUCH faster now.
http://zsnes.sourceforge.net/zsnesw-spc7110-3.zip
This build offers over the previous build even more optimized decompression, and a persistent cache (which at this point I don´t think we really need anymore).
Let me know what kind of FPS you get now, and how much CPU usage it takes (and list which CPU and MHz you have).
Also, please test save states and all that.
We´re almost done here. Once I am, I´ll figure out exactly what it is that I changed, so I can package a new source release.
If you run into any issues, let me know. If the persistent cache for whatever reason is causing issues, delete the *.idx and *.gfx files, and let me know about it.
Thanks.

ZSNES v1.51, with the SPC7110 v2
Okay, I got a new build up. Thanks for the feedback everyone.
http://zsnes.sourceforge.net/zsnesw-spc7110-2.zip
I optimized neviksti´s decompression code a bit more, but this isn´t the good part. I wrote a completely new caching algorithm which is able to cache the complete decompressed data for any game, and search for entries with an upper bound of O(6). What this means, is that once the game already saw a graphic, it´ll be able to recall it instantly. Some initial screens may be slow, but if you ever come there again, it should be full speed. So for example, the first time or two watching the FEoEZ intro, I would have it dipping to 55 FPS on occasion, but after that, all repeat loops are full speed. Also, how long it dips for initially should be less as well, since the games keep on re-decompressing graphics multiple times on each screen, now, that´s been completely eliminated. Hold down fast forward, you may be surprised. In SPL4, in the field, I´m now able to get 196/60 FPS. I also redid the save state code again. It should now generate save states approximately 64KB smaller than before, which are obviously incompatible with previous build. I also double checked the movie code, so that should work too, unlike the previous build which had some issues there.
Todo:
Finish optimizing neviksti´s decompresser so initial loads are even quicker.
Perhaps offer an option to save the cache to disk, so every time you reload a game, it doesn´t have to rebuild it. Let me know if you guys want this or not.
Clean out the old pack path stuff from the GUI and the config file.
Let me know how this new build is working for you, if there´s any issues or not. Please post your results with FPS, and your CPU, and what you think of it.
Thanks.
Edit:
Er, redownload that, byuu caught a bug that I broke the Press A test if you started a game without an SRM. That´s fixed now.

ZSNES v1.51, with the SPC7110
This is v1.51, with the SPC7110 pack loading code removed (although I didn´t remove the GUI stuff for it yet), and real decompression added.
Save states with this version are not compatible with SPC7110 save states of pack loading versions, however SRMs should remain compatible.
Thanks for the code is as follows:
SPC7110:
Research by Dark Force, zsKnight, and The Dumper.
Implementation by zsKnight, Jonas Quinn, and Nach
Decompression:
Research by neviksti, Andreas Naive, and jolly_codger
Implementation by neviksti, Nach, and TRAC
With lots of help from CaitSith2
I spent the better part of two days trying to optimize as much as I could the decompression code, since it was really slow, I was only getting 16 FPS on my 2.5 GHz machine in some cases. Now I get 60/60 and it uses ~20% CPU.

Report how things work. What kind of FPS do you get. Which CPU do you have? How much CPU does it use?
Also play around the games a bit and see if something isn´t decompressing. I´m hoping I didn´t cut any important corners, so if a graphic appears missing, or severely garbled, please let me know.
Also test save states and make sure they´re working good.
Thanks guys.
