Run *.exe file. There will be help.
ps2_config -mode input output
Net to gx -1
Etc
Pretty simple. I've compiled tool for linux and tried it.

I tried it that way, but all I get is "Input directory not found." I've written it like this.

ps2config-cmd -1 SLUS_212.69.CONFIG SLUS_212.69

Am I missing something? I'm a noob with cmd stuff lol

You have to make two folders inside "ps2config-main" one (or whatever you called app's main folder).
In my case it was "net" and "gx".
Now, place all the netemu configs you want to convert inside the "net" folder.
Important part is they have to contain game ID in config's name (just like Aldo's convention - e.g. SLES_509.97.CONFIG).
Without it app will not recognize configs properly.

The commands in cmd now should look like:

cd <path_to_ps2config_app>
ps2config-cmd.exe -1 net gx
Click to expand...

All configs from "net" folder will be converted and placed in "gx" folder.
They can be copied now to /hdd0/vm/gx on the PS3 and their name should remain exactly as after conversion, e.g. SLES_509.97
Modded emu on ISO boot will recognize the game ID and compare it with config's names in /gx/ dir.
If there will be a match - config will be applied to booted game.

Just remember to use gxemu.self from "new_cfg_cmd_ps2_gxemu.rar"!
It is very important step, as without it gxemu custom configs will not work properly - it contains ported 0x0A and 0x42 netemu commands combined into gx 0x2C - as @mrjaredbeta mentioned earlier.

Hope it helps with conversion.
Good luck with testing ;)

That did the trick. If I had a readme it would be different, but I got it to work. Thank you!
I'll make sure to compile a set of configs for gxemu when I do some testing. Waiting on my CECHC Frankie to arrive next week.

Great to hear that!
I'm already working on gx customs testing for some time now, so to avoid duplication of work - anyone willing to participate is more than welcome to my Discord server created especially for this purpose, to discuss all test results: https://discord.gg/sv5TcSTB

Hope to hear you soon guys!
 
@mrjaredbeta some ideas and suggestions I have you might be interested in looking into. I hail from the IT realm so neither me or my contacts have the time or familiarity to look at these things in detail to ascertain their viability but we are quite certain some of these things are likely possible.

- Insert code to prevent a black screen (requiring hard reset) if someone tries to load a PS2 game directly from disc which happens with any PS3 model that lacks the PS2 hardware. We have tossed a few ideas around as to a possible workaround including maybe trying to have the disc treated as an ISO. That way even though the disc won't start you'll probably just have a "unsupported" error thrown out instead of a PS3 just entering panic mode.

- Internal resolution upscaling. This one might be tricky but some ideas have been discussed, nothing concrete has come about as to a possible good way to go about it though, we have toyed with the idea of an interception as the game is loading to output at a higher resolution but this would likely require a configuration file linked to the emulator that automatically runs or a hard coded DLL which we don't know if such an approach would work on the PS3 itself.

- Texture smoothing, exactly the same as what the PS2 can do to PS1 games to clean them up a bit.

- Detection of PS3 model being used and automatic selection of most suitable emulator (manually overridable) to help with n00bs who might select the wrong emulator then complain it doesn't work when its really just them using the wrong emulator lol.

These are the main ideas we just basically scribbled on the back of a beer mat and briefly theorised about, without the level of familiarity with the quirks of the PS3 others have we'll leave these ideas with those who have more of an in-depth understanding of the PS3s PS1\2 emulators, capabilities, and kernels.

Un No creo que funcione pero se podria hacer algo mejor

I don't think it will work but something better could be done with the idea

Interesante nada mal miremos que logran
Interesting, not bad, let's see what they do with this.
 
Great work so far!

I have some suggestions based on my personal use cases for PS1. There are a couple of things that could be improved, but I understand if you are unable to due to technical limitations:

  • I like playing a mixture of NTSC and PAL PS1 games. Unfortunately, when swapping between North American and European game regions, the emulator keeps the region of the first disc that was played. For example, if I play Soul Edge (USA) and then swap to WipEout 3: Special Edition (Europe), the game will run at 60hz instead of 50hz, which makes it run too fast. Maybe there could be some 60z/50z hotkey toggle inside the emulator or outside (Cobra)?
  • The widescreen hack is really cool and all as I use it myself a lot, but it does not account for the fact that there are some anamorphic widescreen games out there (I'll use WipEout 3: Special Edition as an example once again). When I played that game on my PS3 before the emulator mods, it worked perfectly. Now the game visuals break because it doesn't account for the widescreen hack. Could there be some sort of hotkey toggle that can be activated inside the emulator?
If this is impossible due to the space limitations in the elf as you mentioned before, could there be a way to switch which emulator you use via Cobra? Certain elfs could use some hacks like no dithering and widescreen, while others could be very vanilla and only use the backend improvements you made.
