I find the concept of arcade ROMsets quite confusing. I'd be really interested to hear if anyone has managed to extract the ROMs from these Windows store Hamster ports or perhaps the Android APKs. I do really rate the Hamster ports but I really wish they were available on Steam and not the Windows store. What I really, really want though is good quality emulated Neo-geo games as the emulation quality of what we have currently is really poor ( cough Dotemu). So far I have the ROMs from all the mini consoles (besides the turbogfx mini which disappointingly has not been hacked yet), some steam collections (e.g genesis collection), some of the Delta East classix from GOG and Neo-geo ROMs from the Prime Gaming giveaway AND some purchased from GOG (these seem to be the same).

Generally I'm extracting ROMs when the original source is either sub-standard emulation or just inconvenient. The absolute bewilderment of most people when you ask questions about extracting/using ROMs you obtained by actually purchasing - 'Just download them!?'. Super glad to have found this thread, I was starting to feel like a crazy person for wanting to build up a legal ROMs collection.
