Plugin is in development, not fully ready yet.
There’s also the plugin “pause games” that can suspend a game, stopping it from having any CPU/GPU load while you play something else. However it doesn’t free up used memory, and sometimes controls don’t work when multiple games are open, with one game intercepting inputs meant for the other games. So this would be pretty cool if it works out.
A feature pretty close to this is built into Trails in the Sky (remake and original). You can set the default launch option to “Resume latest save”. When you do, hitting play on the game skips all startup logos and the main menu, just giving a quick loading screen then putting you right where you saved.
It won’t restore you to the middle of combat or a cutscene/conversation, but it makes resuming pretty flexible. It would be nice to see other games give attention to this functionality, or at least start to fight supporting technologies on the subject of launch logos.
I’m playing 2nd chapter right now, and yeah it’s such a great QoL feature. It’s a real shame more games don’t do something similar.
