I got a speeding ticket in Colorado on a business trip and later moved clients and thought to myself “meh I just won’t pay it I won’t be back to Colorado any time soon” and I was stopping entering the country on a trip from the Caribbean for “outstanding warrants”. If I can get stopped for that they should know if they have real criminal charges to not play around.
It’s great for specific applications but you would be hard pressed to say it’s a better desktop OS than a gnu Linux distro. Bluetooth is a pretty hard thing to miss.
A lot of commercial software uses mame under the covers (capcom classics for example). IANAL but if you bought that and were able to extract the roms from it that should be fully legal. Just don’t distribute it.
