Describe the FR

I think it'd be helpful to include a brief description in the OPL user interface of what each compatibility mode attempts to fix.

This is how it's currently presented:

It's not readily apparent what Synchronous Mode, Emulate DVD-DL, Disable IGR, etc. means to solve a user's particular problem. A brief description in the UI of what each mode fixes would be beneficial for user self-troubleshooting, without having to search online.

Describe the solution you'd like

An idea for an improved UI with brief description:

It includes a brief description in the OPL user interface of what issue each compatibility mode attempts to fix.

Then, if enough space in UI, could summarize the technical details/method it uses, as referenced here:

Describe alternatives you've considered

One can search online for the modes, but that requires more time/effort, an internet connection, and can disappear or become inaccurate across versions.

Here's a working example running on a real PS2 in OPL Beta 1.2.0. This change can be added to an existing OPL install.

I kept it within the limits of the original layout, but could tweak it for more space/info. Here's all of them but Mode 3*:

*In regards to Mode 3 games: I've found lists from the HDloader days which show many games require Mode 3.

Would these affected games with Mode 3 generally apply to OPL as well? My tentative description might be "Unhook Syscalls: Many games might require this for compatibility. Turns off OPL after game loads." Lastly, I might have another workaround for wrangling these modes.

@rorrexatnys, here you can also find information about compatibility modes. Mode 1 is often used for ZSO, especially via HDD, UDPBD and MX4SIO. A combination of Modes is also sometimes used, especially Modes 3 and 6.

i've found that mode 1 is very benefitial for rhythm games, without it audio gets out of sync. so it might help if example cases like this can be added to the description. of course you wouldn't want to write a whole essay for description, so adding one or two examples would be more than enough.
