Ah okay, gotcha. I wasn't aware that it wasn't all of them. Based on some reading, it doesn't sound like there's a way to get around Digital Video Cartridge issue in MAME/MESS currently.

Have you tried rolling back the install? There should be an updates folder inside your Launchbox folder that has the installers for all the previous versions you've installed. You can just overwrite your current install with a previous one. If it works, you could then update. It's weird that it's not working on even the original PC.

Are you talking about the 1996 one (there are several clue games)? There's a Windows version of it, if so. It's 16-bit though, so you'd need to use DOSBox to run Windows 3.1 or 95. That's kindof a whole other can of worms, but it's doable. 3.1 is significantly easier to do, of the two.

Mednafen (standalone and in Retroarch) does support .ccd format. I don't know about them being in a .7z / .zip though. Mine are extracted. I'm not sure if they'd work when compressed like that. Launchbox does have an extract before start feature which you can check in the emulator settings, but it sounds like that's what you've already tried. If it doesn't work with that, you'll probably need to extract them.

Where is your Launchbox folder located? Has anything changed since your initial install?

Yeah, bulk-editing additional apps would be super handy for certain situations. Before "Launch with..." was a thing in LB, I went through and added ePSXe as an additional app to all my PSX games (as RA Mednafen was the primary). And as Monkus said, things like SSF benefited from additional app chains as well. For a while I used them for lightgun games to start NoMousy before the game and ending it after. Eventually I changed it to just using an alternate emulator entry for Lightgun games that included this behavior in an AHK script, as that was faster than adding additional apps for all of them, but if the time requirement was equal between them, I'd prefer to do it via additional apps (as that'd mean one less "emulator" clogging up my already large list). I know this type of thing isn't a very "sexy" addition, but this is the kind of functionality boost that's more appealing to me than most other potential improvements honestly. And the thing is, more people would benefit from it than probably realize they'd benefit from it - a lot of people probably don't know they need it until something like this comes up and then there's the moment of "Wait, I can't do that?"

No problem! Yes, running as admin or installing LB in Program Files (or Program Files (x86)) causes permission issues where LB and Explorer are running at different permission elevations and so they can't interact by dragging files from Explorer into LB.

Gracias. Estoy seguro de que esto será apreciado por cualquier hablante de español aquí. No hablo español, pero sé cómo usar Google

Being unable to drag items into the UI usually means you're running LB as administrator (which you shouldn't do) or possibly that LB is located in Program Files (which you also shouldn't do).

No problem!

You've got the associated platform named "Seag Saturn". Assuming this isn't what your actual platform is named in Launchbox, you need to correct that to "Sega Saturn". Same issue with your title

No worries. It's usually the little things

You need to use "-freesize". Your screenshot shows "freesize". You have to use the hyphen.

The PS2 Silpheed is actually pretty good. It's got some super cheesy voiceovers about "Large tentacles!" but that's part of the charm. It's a solid shmup.

New configs: Ace Combat 04: Shattered Skies Ace Combat 5: The Unsung War Ace Combat Zero: The Belkan War Silpheed: The Lost Planet Ace Combat 04 has a lot of problems in hardware rendering. Even with some work, the best you can get it in hardware is "not great", with the player's plane being black and all clouds missing. Software doesn't have these issues so it's using software.

You could make a batch to close MSI Afterburner and add it as an additional application to run "after main application" in the meantime.

There is no Demul core in Retroarch. There are Reicast and Redream cores in Retoarch, neither of which are as good as Demul.

It definitely took me by surprise. I went in thinking that it was just going to be another one of the beat em ups but then the first encounter started and I was like "Wait... what?". The production values are really high too, it looks really nice upscaled in PCSX2. Apparently it was made by Visceral back when they were still called EA Redwood Shores. Seems to have flown under the radar.
