Kaillera netgaming improvement:

To make setting up & hosting a game a lot easier: games in your Favorite's list are now added to the top of the Kaillera game list.

Anyone who has done this before knows how painfull it is to scroll through the Kaillera gamelist to find a game to host - especially if the game is very far down the list!  Now, just add the game(s) you want to host to your favorite's list before starting a Kaillera net-game (right click & select Favorite in FBA's game list), and it will be near the top of the list :)

... Coming soon to an FBA near you!

I added a Headache Filter (hack/dip option) to Cyvern.  If you're interested, read on...

Cyvern is probably one of the greatest shooters ever made, it's up there with the likes of DonPachi/Anything by Toaplan & Raizing, etc. (of course, this is completely my opinion)
That being said, there is something wrong with it - the game generates some very loud sounds in the mid-upper frequency band.  If you play the game with headphones, especially when doing a 2-ALL run, and you like to play it LOUD, then you're most likely going to end up with a headache before the game is over.  I theorize that the original game/system had a slight filter on the audio output stage, well.. it's probable, anyhow.  A dip option has been added to mimic this theoretical filter, bringing the mid-upper freq's down a bit so that a 2-ALL game will no longer result in a nasty headache. 
Most people won't play the game that long, or that loud with headphones - but for those that do.. there will be an option for you :)

i think it is amazing as well. When i will have a hardware capable of playing it full speed, i will get into it more seriously.

Can't say i noticed that audio flaw, but any small improvement is welcome  :biggrin:

el_rika, Cyvern runs at fullspeed with my 2006-era P4 :)  It doesn't need too much cpu power.  I've seen PC's in the garbage that are more powerful than my pc, so look around.  This game is amazing and must be played :)

A heavy-barrel of confusion...
I finally figured out the cause of recordings/replays to de-sync with the game Heavy Barrel.  While I was testing some new cpu sync. code w/Hbarrel I noticed that the frame advanced while switching windows.  That's not good - it's supposed to just redraw the screen when Windows(TM) asks a window to re-paint.  Turns out proper redraw support wasn't added to the Dec-0 driver, so the only way it could possibly update is to frame advance - and of course this is going to throw the recording off.  Derp!  Wish I would have noticed this before...  That's fixed now.

Also 2nd player inputs for Snow Bros. 2 have been fixed as well.

Ok, so i've tested a bit more of Cyvern (on Android, as i do not currently have any other means to play it  :smilie: ). The game acts very strangely.  In Fba core .39 with the hack ON, the video plays perfectly smooth, while the sound of course randomly cuts. With hack OFF, it plays full speed, with perfectly stable framerate numbers, flawless audio, but slight video stutter. I even overclock my CPU to 2.7 Ghz and no change, same slight stutter in the video.

In Fba core .43, with speed hack ON it has good sound but similar video stutter (a bit more stutter i'd say), while with speed hack OFF, it runs abysmally bad, half the framerate and very bad cracky sound as well. There is something here i think, some form of regression. Maybe someone could test/compare, with numbers.

aedit: as reference, i play CPS3 games, Cave shmups (PGM), perfectly smooth, not a single stutter with underclocked CPU (1.7 Ghz) and plenty room to spare.

el_rika, sorry about the late response.  I will do some research and see what has changed on a good day :)

Double Dragon.
This game has been kinda bugged since before I can remember.....  With the first report coming from my friend Zazzone back in 2014.  Weird slowdowns, flickering sprites, crash at end of game w/2players (I've personally experienced this happen -twice-.  It's heartbreaking.).  eek.   Well, finally some good news: this has all been fixed with a few small changes to lessen contentions caused by the subcpu and main<->sub comm. ram.

Best regards,

Is it this crash?

If so, it also happens on hardware at random too.

Re: ddragon crash at end:
all of the evidence I can find of this is just recordings from mame.
There's one guy that says it happened on a real machine from a recollection that he saw it happen in an arcade once.
Of course, I'm not doubting that guy, perhaps it did crash.  But after the fixes to our driver, I am unable to reproduce the crash any longer (and I've been trying for quite a while today, 1p and 2p games)  Here's a little testvid https://www.youtube.com/watch?v=W1MT_-G2eys

After what was one of the weirest week-long debugging sessions I've ever had, d_raiden2 (raiden2,dx,zeroteam,etc) and d_dynduke are now working on big endian systems.  (wii-u, xbox360, ps, etc)

also, for arcade games only: everything in the "Misc" category which didn't belong there has been properly categorized.  Hopefully someday we'll get the console games categorized, but we'll need computer-usable data for that.
