1.) Is there a systems criteria for No-Intro? I'm wondering why I see certain systems included and not others. No Neo-Geo AVS, no Dreamcast etc.
2.) Is there an up-to-date list of systems that MAME emulates exceptionally well? For example: I notice that MAME emulates some SNES games poorly, whereas other emulators have no problems with those same games. This isn't a ROM issue. The same SNES ROM that struggled to emulate correctly in MAME works flawlessly in other emulators. Also, if you don't have a G-Sync/FreeSync monitor you'll see tearing in a lot of SNES games emulated in MAME even if you have options like triple buffering enabled. You won't however see the screen tears in other emulators because from what I'm aware, they are capped at 60 Hz. SNES9x for example - I have yet to see screen tearing.
I'd prefer to use the best emulators currently available for each system. I'm willing to sacrifice some degree of authenticity for a smoother play experience.
Maybe I should use RetroArch for Arcade & Consoles since it can make better use of 60 Hz displays? Screen tearing kills it for me and from my experience, enabling anti-tearing options can create audio & input lag issues. Currently I'm saving up for a G-Sync monitor but I'm not quite there yet.
3.) Are all of the ROMs in MAME SWL verified good dumps or will there be the occasional game that is broken in both MAME and other emulators?
4.) What's the difference between TOSEC and SWL ROMs/SWL CHDs? There seems to be a lot of overlap. Yet both TOSEC and SWL stuff continues to exist so there must be some difference to keep these projects going?
