Yes.

The only thing you'd check is the "use emulator" box.

I added the game one as the main "rom" and then added the intro one as an additional-app and named it "Intro".

Assuming you've got the necessary bios files and you've setup your RAM/etc. settings appropriately, the most likely culprit is your .cmd files not having the disks in the right order. The creator bat seems to be picky about the way you select/drag the files onto it and will reverse them in the created .cmd if you don't do it the way it wants.

I wondered what that core was haha. I wouldn't say that that sort of thing is necessarily bad/unusable (I use the MAME 2014 core for a handful of games for compatibility issues), but I'd definitely start with just the "proper" MAME core.

You could try that, but I don't think that'll be read correctly. I don't think I've ever used a parameter like that in quotes. The -cart 2 (filename) definitely would need that whole path in quotes though. I've got some examples of instances where I've done stuff like this for other emulators (like Steem) but none with RA itself...

Etoile Princess Disks 1 (System) + 2 (Data 1): (presumably you'd need 1+3 later) Star Trader Disks 1 + 2:

I can wholeheartedly second Dead Cells. I've played a bunch of it. It's really damn good. It's a bit like if SOTN, Rogue Legacy, and Dark Souls had a mutant baby.

That's definitely not how you want to do it... You make an emulator entry for Retroarch, add in the associated platforms (they have to match the platform names in your library) and add in the appropriate core dlls that you want to use for each platform. If you decide that you want to still use Retroarch but a different core for the same platform, you can make a new emulator entry for that: Then just assign them on a case by case basis as needed.

Yes and no. If you need specific command-line parameters (as is the case with Retroarch in order to indicate the core dll and possibly specifying a custom config) then you have to have an associated platform for it in your Retroarch emulator entry (and corresponding parameters). If, however, it's an emulator that doesn't require any special parameters and you're directing a compatible rom type to it, an associated platform isn't necessary. For example, if I were to direct a C64 rom to Vice 64, and the only associated platform in my Vice 64 emulator entry was "SNES" or something, it would still work because it's a compatible rom and I don't have to specify a command line parameter for it to work. I'm just saying "I want you to direct this file [rom] at this executable [Vice 64]" and that's it. For Retroarch you have to specify what core (only one) you want to use for the game you're about to play. So you're saying "If I use Retroarch to play an SNES game, use the BSNES core. If I use Retroarch to play a Genesis game, use the Genesis Plus GX core" and you're specifying the names of those as dlls in the command line parameter field for each of those associated platforms.

Nope, but I'll check them out.

I dig it. Not a group I'm familiar with.

I love alt-J. Tesselate and Fitzpleasure are probably my favorite tracks of theirs.

Yeah I made a few: I need to get back to making some logos, just been preoccupied with other stuff

You can use overrides to enable/disable/change overlays, but it should be noted that (for whatever reason) overlay data isn't saved into overrides when you create the override via RA's UI. They have to be added to the overrides manually. I've got some more info here: Setting overlays via overrides is a good/easy way to go, though it comes with the caveat that it will only work so long as you only need a single overlay for that core - if you're in a scenario where you have one core that you're using for multiple platforms (like Gambatte for original Game Boy and Game Boy Color, for example) you'll need to split them out into standard configs. More detail on that here:

8bitdo's a well known brand. I'm not familiar with that specific device though. Wireless doesn't necessarily equate to a (significant amount of) latency. The user reviews all seem pretty good.

Some songs/albums are definitely growers. Sometimes I have to be in the right mindset or it has to be the right time (really late at night, particularly, can sometimes put me in the right state to enjoy things more than I would normally). Sometimes there will be a level of depth to the music that you don't initially pick up on or fully appreciate until you've heard it over and over. The mind is a strange and wondrous thing
