[FR] Standalone Pademu application

[YukiXXL]

Checks

• I have checked existing OPL feature requests for duplicates and found none

Describe the FR

I know OPL is meant for HDD games but could the Pademu be used with Optical drive games?

Describe the solution you'd like

Have a seperate Pademu ELF application or add menu entry for OPL to run a optical drive game using custom settings.

Describe alternatives you've considered

A converter for USB to PS2 ? If there is one that works with wires...

Additional context

Having an option that would allow the optical drive to be booted from OPL and allow to change GSM + Cheats settings would also be helpful since to make cheats work with GSM, it requiers seperate ps2rd app with modified config + seperate GSM app.

@YukiXXL don't use PADEMU as it has a lot of compatibility issues. Better use BlueRetro or Wingman PS2.
