Unexpected optmisations
One of the things that I find most rewarding about programming is when you discover an unexpected improvement or optimisation by accident. You can spend weeks carefully tuning and optimising code, only to stumble across a glaring inefficiency in your code which you've never spotted before. One quick change and your application is suddenly noticably faster.
In my daily job I rely heavily on debuggers and profilers to discover bottlenecks in the working on the Xbox, Microsoft provided some excellent performance analysis tools (I see they've finally released PIX for Windows). These days I tend to use AQtime as I'm PC based (it's also one of the few profilers I've found that can handle the size of our libraries at work without grinding to a shuddering halt.)
Without these kind of tools it's a lot tougher profiling on the PSP. Over the past few months I've built a number of custom profiling tools into Daedalus to help me figure out where all the time is going, but the numbers I get out tend to be quite vague, and there's usually quite a large margin of error. I think this explains why the unexpected optimisation I've just found went undiscovered for so long.
A couple of days ago I was browsing the ps2dev forums and came across this post. I was about to back out after a quick scan, when I noticed this comment from Soatome:
PeterM wrote:
but one waits for the vblank
...and that's sceCtrlReadBufferPositive (which you're using) you should use sceCtrlPeekBufferPositive instead.
That's when I realised that when Daedalus was emulating a rom, it was stalling for a frame every time the rom read the status of the pad*. In other words by changing one line of code in Daedalus from
sceCtrlReadBufferPositive
to
sceCtrlPeekBufferPositive
I could get on average an instant 1fps speedup across all roms. What's more, I knew some roms read from the pad multiple times each frame, so they would see an even great speedup.
Frustratingly I had to wait a couple of days before I could try this out. As I mentioned earlier I'm in the process up moving over to a new PC, and I had just moved Perforce over but hadn't set up the pspsdk, which required Cygwin. Daedalus requires libpng and zlib so I had to download and build them too. Then I had to set up Psplink, PuTTY and a whole host of other tools. You get the picture...
Last night I finally managed to get a new build together with the updated code, and the results were every bit as good as I'd expected. In some cases I had to restart the rom just to make sure I wasn't mistaken. I know most of you just want to see some numbers, so here's a few of my observations:
Mario now runs at at steady 15fps in most places, and around 20fps indoors etc (it reaches over 35fps in the main menu, and close to 30 in some scenes.) Zelda now runs at around 8fps in game, and up to 20fps in certain places. The 'nintendo' logo at the start runs at over 90fps The MarioKart Nintendo logo now runs at 30fps, and the main menu (with the flag) runs at a solid 15fps. In game it's a comfortable 12fps. Starfox runs at around 15fps - the intro runs at 25-30fps. Quest64 runs at 20fps.
So all in all it's a pretty amazing improvement for a single-line change. Having said that, I think it would be a mistake to assume that this is an instant fix that will suddenly make everything fully-playable. Although some of the framerates I list above are excellent - faster than an native n64 even - not all roms show this improvement. Don't assume that all roms now run at 15+fps (because they don't.) There's still a lot more work to do to get from a sluggish 8fps to a more playable 15fps (in Zelda for instance). I still need to save a lot more cycles in order to support other features such as sound.
Because this change makes such a big improvement I'm going to try and get another release out sooner rather than later. I don't like releasing builds too often as I think each revision should something worthwhile, but I think this qualifies There are a couple of other optimisations I want to get in this build, so while it might be ready this weekend, sometime early next week is more likely. The new features I had planned for this build will have to wait until R9.
As always, I'll keep you posted.
-StrmnNrmn
*This actually reminds me of a funny story from one of the Xbox games I was working on. We were investigating a sudden slowdown that had been appeared a few days previously. Somehow I realised that the framerate doubled when you unplugged all the controllers. As it turned out someone was accidentally reinitialising the USB hub every frame, and removing the all controllers prevented this from happening.
Awesome info for Nintendo 64 Emulation Fans.

Heres an excerpt
Thanks to a collaboration between Kuju and Wizards of the Coast, D&D Tactics will utilize the equivalent of 13 rule books crammed onto one UMD. According to the dev team, the title will have a more faithful adherence to the 3.5 version of D&D than any game on any game system up to this point. Apparently, a great deal of the authenticity comes from the fact that Wizards of the Coast has kept an exceptionally heavy hand and vigilant eye over the process of creating the game's dynamics, ensuring that D&D Tactics stays as close to the 3.5 rulebook as it can. In addition, this title will be the first ever D&D video game to feature a Psionics character class. Other character classes mentioned include sorcerers, dwarves, and mages. While I didn't know certain facts, such as that in 3.5, dwarves have night vision, I knew that seeing a visual representation of that made a lot of sense onscreen.

This is my first psp coding.
SCI-FI YOYO v0.8
Type: Puzzle <not another space invaders clone >
Joypad moves the cursor, "O" highlight the invaders and "Start" to pause game.
Actually, this is a clone of a mini-game from "New Super Mario Bros.". I love that mini-game, but I don't want to carry both the psp & ndsl while i'm out, so I wrote this game for psp. Of course, I make some amendment to make it more exciting.
I did all the coding and graphic design. Sound effects are from flashkit.com.
Enjoy!

With only a few weeks left to go before we kick off our annual SmackDown Countdown for WWE SmackDown vs. Raw 2007, the amount of available information about the game has been kept to a minimum; it's the calm before the storm, if you will. But just to whet our readers' appetites a little before we get started, THQ has granted us access to a few new tidbits of information -- namely the confirmation of a handful of new superstars and a sneak peek at the final box arts for the PlayStation 2, PlayStation Portable, and the Xbox 360 (pictured).
The box art may look familiar to those of you who have been perusing online retailers over the last 24 hours, as it started to appear on select outlets sometime yesterday evening. Trivia fiends should take note: this is the fourth time in eight games that Triple H has appeared on the cover in some form or another.
But on to the more pressing question: Which superstars have been confirmed for today? "Legend Killer" Randy Orton, "The Animal" Dave Batista, and the dog-toting diva, Torrie Wilson are the newest three to join THQ's growing lineup. The addition of this trio brings the current roster count to 12, which already included Shelton Benjamin, The Undertaker, John Cena, Triple H, Rey Mysterio, Booker T, Chris Benoit, Kurt Angle, and Johnny Nitro.

As popular dance phenomena in videogames go, break-dancing exudes the sort of urban cool that's practically defined Sony's console since Rockstar's GTA III kicked off the whole gang warfare fad. Line dancing, bogling and sychronised pelvic clenching, on the other hand, don't - which is a shame, because 'Bogle-Boy' has quite a nice ring to it.
So then to Sony's B-Boy - a strange hybrid of rhythm-actioner and fighter, all wrapped up in a gritty hip-hop bow. Developed by FreeStyleGames in collaboration with noted real-life B-Boy Crazy Legs (real name, Richard Colón, hilariously enough), B-Boy puts gamers in the sneakers of a break-dancing wannabe, tasked with challenging some of the greatest B-Boys in the world.
Single-player progression occurs through the 'Livin' da Life' career mode where, from the game's hub (known as The Lab), players are free to practice their B-Bobbery, consult their movebook, take on challenges from in-game opponents or even change their streetwear. First things first though, tackling the tutorial is highly recommended - mainly because B-Boy doesn't play quite like anything that's come before.

'Street culture' is getting squished down into tons of microgames in Hot PXL, due for a PSP release in November. Have a look at this new trailer to see just how it works.
Hot PXL's compilation of microgames is themed around today's street culture of DJing, breakdancing and buying trainers, and comes across as a sort of hip Wario Ware.
The final package will have over 200 games, 10 bosses, two-player mode and an original soundtrack from our friend, French 'urban culturist', Jonathan Choquel. There's also the promise for additional downloadable content.

It's not often that a game announced for a console just three months before the system first hits the market is confirmed as a launch title, but that's exactly what happened today out of Ubisoft. The publisher is bringing its combat flight sim Blazing Angels Squadrons of WWII to the PlayStation 3 as a launch title.
The game has already been released on the Xbox 360, Xbox, and the PC, and was also announced as a launch title for the Nintendo Wii. Like the Wii version, Blazing Angels on the PS3 will take advantage of the console's motion-sensing controller, letting gamers pilot their plane by moving the controller. The PS3 edition will also feature new missions, as well as support for up to 16 players online.
Currently in development by Ubisoft's Romanian studio, Blazing Angels puts gamers in the cockpit of a World War II fighter plane. Players will fly through re-creations of some of the war's most famous battles, including the attack on Pearl Harbor and the Battle of Britian.

After calling on Take-Two to prevent its upcoming PlayStation 2 game Bully from falling into anybody's hands, Florida lawyer Jack Thompson is now trying to get his own hands on it, and before anybody else at that.
Thompson filed a petition today with the 11th Judicial Circuit Court asking for Wal-Mart and Take-Two to furnish him with an advance copy of Bully so he can have "an independent third party" play the game and determine if it would constitute a public nuisance in the state of Florida (in which case it could be banned).
"If Bully is indeed safe for children's play, then petitioner will be the first to say so," Thompson said. "If it is not, then not only will the underlying action be brought sounding in Florida nuisance law, but also possibly and most likely in fraud as well."
One of Thompson's complaints centers around retailers like Wal-Mart accepting preorders for the game without age verification, because the game has yet to receive a rating.
"Is it a 'Mature' game not appropriate for anyone under 17 or is it a 'Teen' game sold to everyone," Thompson asks. "The ESRB refuses to say and appears to be withholding from the public the rating of the game in order to quell controversy for its corporate collaborator, Take-Two. ... This withholding of rating information from the public about a game that the ESRB has had for over a year is outrageous, made more so by the fact that Wal-Mart is actually pre-selling Bully with no rating whatsoever for the game, to anyone of any age!"
He added that preselling a game that hasn't been rated yet is "akin to a pharmaceutical company selling a new and controversial drug without prior FDA approval," and he accused Take-Two of instigating "a new wave of successfully orchestrated harassment" against him. So far that wave consists of a series of phone calls he received Tuesday morning from a caller who identified himself as "Peter," called him a sexual deviant, and threatened his life. Last December, a 16-year-old gamer in Texas was charged with a misdemeanor for threatening to torture and kill Thompson.
Take-Two had not returned a request for comment regarding Thompson's petition as of press time.

Well, they missed their June launch plans by a couple of months, but Sony has finally managed to ship their 50GB Blu-ray discs to a doting public. Just as expected, the discs are going for that $48 slap-in-the-face of a pricetag, and you'll still be better off buying a pair of 25 giggers, or a few DVDs if you're looking for price-per-gigabyte. But if you've gotsa have the latest and greatest, or just would like to find something nifty to do with that new Blu-ray drive of yours, it doesn't get much hotter than 2x 50GB discs with AccuCORE protection. Sony is still promising rewriteables for later in the year -- these discs are just write-once -- and we're guessing prices won't stay so lethal forever.
