Post: PS1 Emu Selfs - Swap Discussion
05-12-2011, 03:37 AM #1
(adsbygoogle = window.adsbygoogle || []).push({}); So, I was bored today and decided to load up dev_blind and swap the selfs around to see if it'd crash with an official disk. It didn't, but it gave me a weird result that benefited me...

So, has anyone played Chrono Cross on their PS3? Well, that's what I tested. In the opening of the game, if you press start when the squaresoft logo animation is playing it'll bring up the main screen to press start. Normally on this screen you (or atleast I do) get 3 vertical (up and down) lines of corruption, almost like the video is stuck n blanks out (think of blocks when browsing through a video file in old school VLC). They flash n go away so they aren't that big of a deal, but it may help with unknown issues too. This game also randomly has issues in battle on ps3, but they are quite rare as I've only had a couple problems, and CC lagged in battlefields on psx to begin with, so i'm not sure if it does anything with this or not.. Most people I've seen reply to topics on CC say it works fine on their PS3 anyways.

Let me start by saying, I don't recommend you just start swapping files around in your dev_flash, it's unsafe so don't try it.

Well, what I did was backup the ps1emu folder from flash first obviously, then i opened the folder via ftp and deleted ps1_emu.self.

I made a copy of ps1_netemu.self and renamed it to ps1_emu.self. I then FTPd this into the the ps1emu folder and did a complete power cycle (shutdown console with controller, cycle power switch (i have 80gb launch fat).

I booted back up, launched my game, no corruption. Yay. So I swapped back to the original ps1_emu.self. Power cycled again, they came back. I continued power cycling til I tallied 30 starts with corruption in a row.

I then put the ps1_netemu.self renamed to ps1_emu.self back in place of the original again, and proceeded power cycling. They went away again. I tallied 30 again with no corruption.

So, has anyone else ever messed with these selfs at all? Any ideas wtf's going on? lol

and just so you know which screen does it, here's a SS.

Note: The SS for the corrupted image is not actually from ps3, they are just photoshopped for reference. They actually appear below the arrows above the "corrupted image". Ill try and youtube it tomorrow to show you what i mean..

PS3 tested on is running 3.55.1 Rebug

This may be blurry and stuff, but it's just a quick (although 12min long..) video on what doing this, causes to happen. I recommend skipping through it unless you wanna listen to my nasally annoying voice lol. also i realized after I finished making it, you couldn't tell wtf i was doing so, i made a short video which is horribly blurrier with close-ups of hex workshop and flashfxp.


Demonstration


Note: Ignore the PS2 Emu Files in the video like they arent there. it was just quicker to put the file im using in there.

but the one thing i dont understand when i tried to go into the file manager, whenever i tried to move or switch files like the dev_flash an error would pop up and it would flash a bunch of numbers on the screen and then the ps3 beeps 4 times, then shuts off
i have a ps3 fat 40 gb on 3.55 its one of the first ones that came out
please help

Well, I'm using dev_blind, so make sure you run that and that you are trying to access flash from dev_blind, not dev_flash. If you are trying to access dev_blind folders/files, I had problems using multiman, that's why I opted for OpenPS3FTP instead. Also, I know all PS3's can play PS1 Backups, but I'm not sure how this affects any other model besides the og 80GB.

Also, I've never heard of a bunch of numbers appearing on the screen... Which 3.55 are you using? Kmeaw?

Btw, I hate flies. Why do I have to live by farms... lol
PS>Ill BB tomorrow night. bye for now

Ok, so I was going through a Compatibility List I found on wikipedia and I seen Tomb Raider locks up in the main menu if left inactive for 15 seconds.

So, to test if this helps besides graphical issues, I'm going to check to see if my disc has this issue by going back to the Disc Self. If this happens on my console, I'll put another video up if the simple swap fixes it.

Netemu is used for games downloaded from the playstation store.
/dev_flash/ps1emu/ps1_netemu.sel (Can be found here)

Emu is used for games ran from actual playstation discs
/dev_flash/ps1emu/ps1_emu.self (Can be found here)

Well beside the usual drm decryption code that is most likely existing in the net version of the emulator, I figured what one of other difference might be. The netemu one has better upscaling than the disc version of the emu !

In other word your games will look better when you purchase them from the playstation store even if you run the very same version of the game from disc (thus sony made the upscaling worse on those on purpose)!

Now you also notice it in Wild arms... and thats why is a little bigger than the other..

:pedo:


This isn't an issue from upscaling though, it does it on SD.

Edit: Thanks for deleting my mess up. Smile
