Loading ROM via -cdfile invocation doesn't load corresponding config file

[porg]

Environment

• PCSX ReARMed r23
• Device: OpenPandora
• OS: SuperZaxxon v1.76 update 3
• Launcher: Pandafe 0.3.0.2-b464

Precondition

• ROM got customized display setting, was created via "Save cfg for loaded game" in menu.
• Is persisted in corresponding config file: appdata/pcsx_rearmed/.pcsx/cfg/game-name-ID.cfg

Reproduction 1: Loading ROM via internal Menu loads corresponding config

1. Open PCSX ReARMed.
2. Press SPACE to open menu.
3. Choose "Load CD image".

→ ✅ PCSX loads the .CFG file corresponding to the chosen ROM.

Reproduction 2: Loading ROM via -cdfile invocation doesn't load corresponding config

1. In Pandafe as the GUI launcher
2. Select a Playstation game and press game button "B" to launch it
   • Pandafe is configured to launch pcsx with -cdfile %g
3. The game is launched successfully…

→ ❌ …but its corresponding .CFG file is not loaded.

Expected / desired behavior

If pcsx is launched by external invocation (with -cdfile /path/to/rom): 1) by default loads the corresponding .cfg file from within the appdata /cfg/ directory

• Minimal fix which would guarantee individual game config overrides to also work with external launchers such as Pandafe. 2) for additional flexibility may offer overriding arguments:
  • a) --config-dir /path/to/cgf-dir/ where is attempts to find a proper config file by name/ID match
  • Possibility for a --config-dir per launcher (isolated from the main /cfg/ )
  • b) --config-file /path/to/particular-rom-name.cfg
  • That way you could create different customized launch configurations per game.

Note: I did not see any pcsx command line argument which would allow 2a or 2b.

Duplicate of #163 and should be fixed now.

Cool! Improves the integration of PCSX with external launchers! Thanks!
