PS3 Laggy ps2 games..

Look at here: http://www.psdevwiki.com/ps3/PS2_Classics_Emulator_Compatibility_List
Someone noted "battle stadium d.o.n" as "playable"... this is a namig convention that means "The Game works perfect without any noticable errors" but now you are mentioning problems with it makes me doubt if whoever noted that in wiki played it entirelly
The other game is not mentioned in the list

I dont understand what you mean with... "game 750 of the time" and "the m249 sounds like firing a deagle" though
And not sure which game you mean

Some PS2 games when running on PS3 has problems... and sometimes are solved by using a CONFIG file

 

Like I said before, the HAN Enabler patch is only an encryption key swap, it makes little sense for a different encryption key to have an impact on performance.
Moreover the key is only used during the phase of decryption of the program files which takes place before executables are loaded, not when they run.
The issue needs to be investigated further to determine a culprit..

 

Are those lags you guys noticed only on games using the ps2_netemu?
Of course, it goes without saying that tests using 14000 pirated rap files in the home folder are not valid tests!

 

But have you compared running the emulated game with HAN & without HAN?
Emulated ps2 games on ps3 are often laggy by nature so to implicate HAN files & patches as a possible culprit we must only compare frame drops with the same game running with ps2_netemu on CFW. A comparison with real ps2 or the emu on a BC console is not helpful.

 

But silent hills origins needs a CONFIG file, this is what it tells the PS2 compatibility page on wiki
And that CONFIG file is not official (it was made by mysis)
Usually the official CONFIGS (released by sony together with the game) repacked for the PSN store as "PS2 classics" solves the 100% of the game problems
But this is a custom CONFIG so Silent Hill Origins cant be used to determine if HAN has some performance penatly in PS2 emulation

And i dont know if Silent Hill - Shattered Memories was released as "PS2 classics", i guess not because is not mentioned in the wiki PS2 compatibility list... so we are in the same scenario

To know if HAN has some performance penalty with PS2 emulation is needed to use an official "PS2 classic"

 

What i mean with this... is if the game is an official "PS2 classics" this assures us it has passed the "quality control" of sony team they made before publishing it

In theory... that quality control is very strict, because they cant sell a "product" that is faulty
So is virtually imposible to exist a "PS2 classic", PS1 classic" or "PSP remaster" with problems published in the official PSN store
People is paying for it, so the game should work perfect... for the consumer is not aceptable at all if the game has some problem

There are some exceptions, lol, because you know... that quality control team sometimes misses some problem (small ones) and the game reaches the store without them noticing
But when this happens people reports the problem in the official blogs, etc... and they uses to review it (to prepare a CONFIG for it or improving the ps2_netemu emulator)

Think in all this like if are very strict rules... the point is... if a game was published in the store it means it "should" work 100%

And the ones not published in the store... well... falls under several categories... there is not a single reason why a specific game was not published in the store
Sometimes is just because sony did not have the license from the original company that made it (the other company owns it, but there is no legal agreement with sony).. and other times is because the "quality control" team found multiple problems... or just small ones (but enought to takedown the publishing of the game)

And i think the tool you are using to create the PS2 PKGs contains that CONFIG files too, are the same

The ones under "NET" category are official and are going to fix the game 100%
"GX" and "SOFT" are official too, but the success ratio is doubtfull because was intended for other PS2 emulator types (not the NET emulator you are using in HAN)
And the "CUSTOM"... well are made by the community... some could fix the game 100%, others could fix the game only partially, etc... is a collection of experiments (partially or completly sucessfull) made by people trying to fix some problematic PS2 games
