I do.
but who are you? are you a 10 -15 year old who has never even seen or played pacman or galaga? if something was wrong, how would they even know? as was said by jim, these kids will play it for a while...get sick of it, and that will be it. for the sake of ease, 60-in-1 is the way to go here.
they use a version of MAME that is under a non-commercial license and are completely illegal to own and use.
you want to get pedantic, literally everything mame is illegal with anything but homebrew roms that people have posted there and expressly allow their use. nobody has rights to any games you'd ACTUALLY play with it anyway. besides, mame changed their copyright cause the implication of use was going to get them in trouble.

that's it. that is all of their legal licence now. they are basically hoiking the legality onto the person using it. so i guess what should happen is the 60-in-1 should update the version of mame it's using then?
the way i see it you stealin' roms owned by companies like midway and nintendo and go with mame... or you violate an old licence for software from a group who propose you steal roms from somewhere else to use with their software... (oh, provided its legal for you to do so in your country of course.) and you stealin' roms owned by companies like midway and nintendo i personally don't see a difference either way.
but of course, you have permission to use those 10,000 roms you got on you groovymamebitkitjrokmisterwhatever you got there. i'm sure you have your garage stuffed to the roof with the mountains of paperwork from nintendo and sega and midway and capcom and cave and and and and... allowing you to download and you can legally play the games.
don't whiteknight mame as being good and 60-in-1 is evil. literally everything is illegal... and trying to make it legal is impossible and futile cause everyone wants theirs.
you can only justify choosing one or the other and convince yourself that it is good.
i guess also this falls into the cognitive dissonance balance theory and it's correlations... the premise: the software on the 60-in-1 is illegal and the roms are illegal, therefore 60-in-1 is illegal and mame is legal and the roms are freely available...so it must be not illegal. our drive to maintain psychological balance allows us to justify one being good and the other bad, all the while, both actually being bad.
