By the way. Is there any work around, I am thinking of for example being able to point out a specific (older) version of a binary to install?
I guess this could be good also in the case when several clients happen to run not the latest version of a Ported game (multiplayer), and then a new client installs the game but runs into compatibility issues when joining the multiplayer game.
@Meneer-Jansen You will be limited to inferior emulators for just about every system. This means graphics and sound won't be accurate depending on the system emulated.
I don't use battery packs so I haven't looked into undervolting/underclocking a pi4 or if it'll make much of a difference in saving power.
How are you connecting the devices - do you have an USB hub (and which type) ? Can you check the system log with dmesg to see if any errors appear there when the controller becomes unresponsive ? What power source (and no, a phone charger is not a proper power source) are you using ?
You should read the documentation, especially this page, and take a close look at the compatibility lists. Those lists are Google spreadsheets that do have some crowd-sourced testing results, so you might have to try something to see for sure what works for you (or what acceptable performance means to you). Fortunately, most of the classics work well, but since this is somewhat subjective, it's hard to have a "definitive" list.
@herb_fargus lol. Found a half a beetle. When i was a kid i opened a snack size dole can of mixed fruit and it was just water and rocks. They didnt even give me mixed rocks....
My ex wifes ex husband got a back of doritos and it had a beetle that was coated in the cheese powder and deep fried. It was pretty gross seeing the pics.
