ice VS libretro-dolphin-launcher

We still don't have anything that can do what CORBA could do. gRPC doesn't even come close.

If you are interested in this type of technology, I recommend looking at ZeroC's Ice. https://zeroc.com

It's CORBA with all the warts removed, and a lot of other useful stuff added.

Are you saying: “This solution does not look particularly great”? Well, there's more. The system was not just your average, boring product, it was a modern and fancy distributed system, so it used a framework called Zeroc Ice. This is an RPC framework that also provides deployment configuration, service discovery, SSL encryption and more. By itself it’s rather interesting, but in our case it was used almost everywhere. Majority of the functions in the system were exposed as RPCs, which made them effectively globally visible. And they could call other RPCs and they called even more. And every call produced some side effects that were quite often used in condition expressions of “Algorithms” defined with DSL. These conditions were of course quite heavily nested. As a result, even though we could see in the monitoring interface which steps were already passed, it was almost impossible to tell what would happen next.

What is ICE? In-circuit emulation? RPC framework?

It's something we've talked about for a long time, and it's not technically impossible (or even very difficult, really). We've long had cores that can launch external processes for PCSX2 or dolphin, or this general one that launches bash scripts in linux.

There are better options that have been commented already, but I did make a Dolphin Launcher core. Someone forked it and made a PCSX2 fork of it.... https://github.com/RobLoach/libretro-dolphin-launcher

you might also check out the 'dolphin launcher' core, which just calls an external program: https://github.com/RobLoach/libretro-dolphin-launcher.
