When you say several systems now all show the same shader are those systems all using the same core, ie gameboy, gameboy color, gameboy advance? If so it sounds like when you applied the shader you saved it as a "core override" applying it to all systems that use that core (or you may of even saved a "global override" meaning its now used for everything. You need to load a game that uses the shader, go into quick menu/shaders and click on the button that is a "remove override" it will be named differently depending on what sort of override it was. In future you should be using "content directory overrides" for things like this, Sega is a good example of this, the genesisgxplus core emulates sg-1000, master system, megadrive, mega cd, pico, and game gear, you wouldnt want the same settings for all those systems, especially game gear and the home consoles, so you save a "content directory" override. This saves those settings for any game loaded from the same folder as the current game, so if you had a game gear game loaded in future any game loaded from that same game gear rom folder will get the same settings, but something from the megadrive folder wouldnt.

Why not just set the hotkey in retroarch?

You can just delete the license.xml file in the Launchbox folder, and replace it with a legitimately purchased one. https://www.launchbox-app.com/premium

If its a separate button away from the actual controls are you sure its a "controller" button and not a keyboard key? It may just be a "escape" key.

I havent used demul in years, but if i recall what we used to do was add two demul emulators to launchbox with different names like "demul dreamcast" and "demul arcade" as different settings are required for arcade games.

Set controller combos in Retroarch for save state and load state and use the button combo while in game. Some advice though, DO NOT rely on save states, when a emulator updates they can, and will break, always use actual in game saves via the games save system if you actually value your saves.

The "third" menu is the game details screen and can be turned off in the settings, it can also be mapped to any button/key.

We cannot help you with that, downloading roms you do not own is illegal.

Any reason you are using the worst Saturn emulator there is? My advice would be to use the far superior mednafen/beetle Saturn emulator/retroarch core.

That is expected behaviour for the MAME "Fullset" importer it expects a fullset, not a limited collection of roms which 700 certainly is. Also yes it does not actually look at the files you have in the folder, as any fullset has the same games, it gets that working games list directly from the mame.exe, and adds the rom names to Launchbox, not the roms themselves. If you have a limited curated set of mame roms you need to use the standard rom importer and not the mame fullset importer.

Launchbox has nothing to do with your controls in emulators.

Always makes me laugh, seems to be absolutely essential that the user be on the latest version of Launchbox, but at the same time is using a OS that came out 15 years ago and is completely unsupported at this point, why one standard for one bit of software and a different standard for the other? Nobody should be using these old operating systems at this point, they are a security issue as they are end of life and no longer updated to stop current day threats.

Set mame's "default.cfg" to read only, then it cant be altered.

if your mame romset is 0.109 thats not gonna work with current versions of the emulator, its like 20 years old. manually download mame 0.109 from the mame website and use that, retro808 is also correct on that command too, it needs removing with a build as ancient as that.

It will only import bios files if you messed with the filters and disabled the one that excludes them, probably the "skip non playable games" one or similar if i had to guess.

No it doesnt as far as i know currently, but it probably should as mame is different to other systems/imports as files are not actually imported, and there are thousands of useless ones which you wouldnt want installed that are probably being seen bt the auto import process.

The mame rom folder should probably be excluded from this feature if having previously used the mame fullset importer, just add a flag at initial import if it was used so its ignored in future.

Looks like you may be on Windows 7/8 and unfortunately those are no longer supported due to other librarys Launchbox uses no longer supported 7/8, in this case chromium. 13.9 i think was the last version that supported those OS's so if you dont have that installer in your Launchbox/Updates folder you will need to reach out to support@unbrokensoftware.com and request that file.

I dont emulate on android so i cant say for sure, i will say though that this is nothing to do with Launchbox itself. Launchbox would only care in the Launchbox UI, once you are in a game it's up to the emulator what peripherals are supported. Maybe try a different emulator, one that isnt going through Retroarch's input layers? https://play.google.com/store/search?q=ZX Spectrum&c=apps&hl=en&gl=US

https://docs.libretro.com/library/fuse/#controllers-usage Scroll lock on computer systems in retroarch should lock/unlock the keyboard to the emulator (as retroarch itself uses the keyboard for a lot of functions by default).

Just re-run the import, but this time against the updated mame.exe (as the working game list is extracted from the emulator version that matches the romset).

Maybe related to this?

Personally i run all of those platforms through retroarch.
