PS4 [Research] PS2 Game Status on (PS4's - PS2 EMU)

oh WOW! Dude, that was incredibly fast, thank you :) I'll give it a try right now. I see how you've used the addresses, but how did you convert "word" to 0x48421000? Thanks!

patch=0,EE,001d8020,word,1000000f

patch=0 = apply only once (not needed more, as value don't change here)
EE = Emotion Engine
001d8020 = Memory address
byte,short,word = byte 000000FF, short 0000FFFF, word FFFFFFFF
1000000f = Patch value, so in word case apply full opcode

eeInsnReplace(0x1D8020, 0x48421000, 0x1000000f)

eeInsnReplace = like patch=1 in pcsx2 but applied only if meet original opcode on selected address
0x1D8020 = Memory address
0x48421000 = Original opcode found on this memory address
0x1000000f = Opcode that will be used instead of above

Getting missing original opcode (require game executable, or even other game elf sometime)

Extract SLXS_YYY.ZZ file from game image
Open file in ps2dis
Push G on keyboard and provide needed address (001D8020 in this case), push enter.
Voila.

You can additionally click Analyze - Invoke Analyzer to get info about functions, not really needed while porting patches.
 
Excellent information, thank you very much, easy to understand and hopefully I should be able to put this into practice myself in the future -- unfortunately, in this case, it wasn't successful. I still get the same instant freeze at the start of combat :( Ah well. Thank you for trying, nonetheless!

To check that patch from pcsx2 is exactly for that issue, just un-tick "Enable Automatic Gamefixes" and run game AGAIN. If it freeze in the same place, then this CAN BE the same issue. If it freeze in other place THIS CAN BE different issue.

PS. Try this in config (not lua)

--fpu-accurate-range=0x100008,0x430000

Slow af, but can shed some light on issue.

Thanks again, Kozarovv! I'll try that shortly and see how it runs in PCSX2, then I'll try the FPU option :)

Good work btw, i been looking at your edits in wiki latelly and wanted to tell you ;)

Oh hey, thank you very much! <3
 
Okay, now this is weird. Knockout Kings 2002 freezes exactly the same way on PCSX2, with *or* without the automatica game fixes. There's a fix listed in the gameindex.dbf but it obviously doesn't work :\ There's even a report on the official PCSX2 wiki from someone, in January this year, stating that it doesn't work and that it freezes as soon as you start a fight.

So, oh well, I guess that's that then.
 
Hey guys, sorry for constantly picking your brains on fixing stuff, but I'm having some trouble with the "Disc Swap" option - chiefly that it doesn't actually do anything :| Okay, backstory;

I've been trying to inject Codebreaker (via u/wLoadElf, like I do with many other titles) but I can't edit the ISO of my game. It's Wild Arms Alter Code F and it's a dual layer, if I try and extract or do anything with it I only get Layer0 and the game doesn't work, Apache3 will allow me to extract both layers just fine but cdvdgen (1.5 or 2.0) won't let me create a dual-layer image, only single layer, so I can't copy over the uLaunchELF/Codebreaker.elf files to the disc as I usually do. My idea was to use the disc swap function, create a uLaunchELF disc, load Codebreaker, then when it tells me to insert the game disc, I'd use the PS menu > disc swap option, and continue. Only, that doesn't seem to do anything :\ If I reboot via Codebreaker I'm back at the disc01 uLaunchELF menu and it doesn't load disc02 (Wild ARMS) >_<

Does anyone know how to truly work the disc swap setting? Or perhaps even how to edit/flatten a dual-layer ISO into a larger single-layer? Something/anything so I can inject Codebreaker into the ISO? Thanks guys!

Also, I've added dozens more titles to the wiki and I'll be continuing to do so, it's a blast! Considering the PS4 PS2emu isn't as compatible as the PS2netemu from PS3, it's still remarkably capable! Over 300 playable games and climbing. Right now I'm trying to get Phantasy Star Universe to work, the game looks and runs great, but unfortunately has some geometry/texture/lightsource flickering in places. Not "devastating" but definitely noticeable.
 
if using multiple disc pkg

remove this from config.txt:

--playgo-disc-per-chunk=0

or just put # in front... eg. #--playgo-disc-per-chunk=0

also, if using the jak emu, you also have this option:

--switch-disc-reset=1 or --switch-disc-reset=0

meaning you can swap disc without the emu resetting.

I didn't even know there was a "no reset" option .. however, the problem I'm facing is; when I open the PS menu and select "Switch Disc", it says "you are on Disc 1, choose the disk you wish to switch to" -- I choose the next disk and there's no response. Nothing happens. It doesn't switch, or if it does switch it doesn't show anything. If I open the PS menu the same thing, shows as still on Disc 1, so when I press "Okay!" to the Codebreaker "Insert game disc" option, the emu resets back to Codebreaker's disc instead.

I'll try out your no-reset command and see if that works, thank you :)
 
Are you serious!? HAHAHA! Really?? Holy crap, haha!

~edit~

That fixed it ! I hadn't flippin' noticed X/O being swapped. However, as said, the game resets when changing disc... so I'll remake the PKG right now with your "no-reset" command and hey, see if it works. Sir, you rock, thank you :)

~edit~

It worked ^_^ Now when I switch disc it doesn't reset the emulator, and even better; it remembers the last disc you had selected when you close/reopen the game later. Nice. Anyhow, now I have a game that has two discs baked in, the Codebreaker ISO and the Game. Run the game, select cheats, then start game-- when it prompts for disc, open PS menu, change disc, go back to game and hit continue. Loads right up as if Codebreaker.elf was on the game itself! I love it :D

Thank you, Stayhye, it's most appreciated!

No problem, BTW, does anyone here know the correct usage of "--host-pad-enhance-deadzone=Legacy value/ignored"? what is legacy value/ignored? Trying to fix the slide in cold winter....
 
Amazing. You guys are amazing <3

Surprised and happy to report that Wild ARMS Alter Code F now works great, no longer crashes/freezes during Jack's prologue, runs great and looks great, doesn't even have any text corruption issues that plague PCSX2 (without the pixel offset hack applied) -- there is some slowdown during a handful of spells due to effect, mostly fire, which I'm not sure how to even begin fixing, they're not even visually impressive or system taxing either, but egh... small problems compared to the whole game running properly now :)

what emu are you using? Any fixes applied?
Click to expand...

Jak emu and no fixes whatsoever, just the config-txt you see coded a few posts above :) I'm currently rebuilding and trying with

Code: 
--gs-progressive=1
--threaded-gs=1
--gs-adaptive-frameskip=1
--gs-optimize-30fps

Though I think optimize-30 is a bad choice, because I *think* WAACF is a 50/60fps game based on region, not 30fps.
