Couple of issues after installing PS2CONFIG.pkg & a few questions.

[Yaerveth]

Hey there, I've been trying to find someone to make a config file for InuYasha: Secret of the Cursed Mask and someone suggested that I should install the latest PS2CONFIG.pkg file. I did, and my PS2 saves were not detected for a few minutes, but they came back after a while. What could've caused this? Keep in mind that I'm using HEN and the saves were visible on XMB, but not detected in-game. I was also unable to connect my dualshock wirelessly when this happened.

Other than that, I have a few questions:

• How does this PS2CONFIG.pkg work exactly? I installed it, but I have no idea how it works.
• Where exactly on HDD does it get installed?
• How to remove it just in case?
• Is there any possiblity for it to break my save files in the future?
• I'm using PS2 Classics GUI to convert ISOs to .pkg files, then install them on my PS3 to play them. Do I really need this PS2CONFIG.pkg?
• Does it have the config I'm looking for? If not, is it possible for you to create a config for SLUS-20913 or teach me how to do it? The code should be like this:
  3D 00 00 00 57 44 00 00 35 00 00 00 00 00 00 00

Credit goes to mrjaredbeta from PSX Place for the code. Thanks in advance!

How does this PS2CONFIG.pkg work exactly? I installed it, but I have no idea how it works.

It only required on HEN, since all the non-encrypted PS2 CONFIGs come included in webMAN MOD installer.
It's a database of CONFIG files that webMAN MOD uses to auto-configure the PS2 Classics and PS2 ISO.
All the steps needed are done automaticly in background. So the user don't have to do anything except install the PKG only once.

Where exactly on HDD does it get installed?

/dev_hdd0/game/PS2CONFIG

How to remove it just in case?

Delete PS2CONFIG from Game Data or use a file manager to delete the folder /dev_hdd0/game/PS2CONFIG

Is there any possiblity for it to break my save files in the future?

No

I'm using PS2 Classics GUI to convert ISOs to .pkg files, then install them on my PS3 to play them. Do I really need this PS2CONFIG.pkg?

No. However the CONFIGs included in the PKG are needed to include (or encrypt) them within the PKG file generated by PS2 Classics GUI

Does it have the config I'm looking for? If not, is it possible for you to create a config for SLUS-20913 or teach me how to do it? The code should be like this:
3D 00 00 00 57 44 00 00 35 00 00 00 00 00 00 00

If the CONFIG is that one. You only have to paste these hex codes in an HxD (or any Hex Editor) and save the file.

If you need to create your own codes, it's more difficult and probably will need some trial/error.
Here are some suggested links and basic information shared by mrjaredbeta to create your own codes.

💡HEN is not the best environment to test/create PS2 CONFIG codes since it requires to encrypt the codes each time.

Thank you for your detailed reply and addressing the issues individually and teaching me how to create a config file!

I downloaded another random config from PS2 CONFIG Database to see if I'm doing anything wrong. When I compared the two files, they look correct except for the one I downloaded has two lines unlike the one I created. Does it look right to you? I copied the codes into the file, saved it, and renamed it SLUS_209.13.CONFIG. It originally had .file extension. If everything looks right, then I'll proceed testing it.

It looks correct. Take in count that the decrypted CONFIG only works on CFW.

For HEN you need to package the encrypted BIN.ENC with the encrypted CONFIG in edat format that is around 48KB in size.

Alternatively you can rename the BIN.ENC and CONFIG as Name-of-Game.BIN.ENC and Name-of-Game.CONFIG, to "mount" it through webMAN MOD, multiMAN or PS2 Classics Manager. The .BIN.ENC stored in /PS2ISO require to be launched through PS2 Classics Launcher (aka PS2 Classics Placeholder).

It worked! However, PS2 Classics PKGs don't detect any memory card thus I can't save or load my previous saves now. To clear up some further questions:

• I did not create a virtual memory card because it's not needed since I followed this guide, and I never had any issues until today.
• I'm not using PS2 Classics Placeholder or whatever that is.
• I'm not playing them through ISOs or webMAN.

What could be the issue here? I basically can't save any of my PS2 games anymore. I'm not sure if it has something to do with this or something else, but you seem to be the most reliable one on this subject.
