Dig and Reset Collection launchers (I have both, Reset is fantastic) work fine on Nvidia Shield...why LB wouldn't?

Your comment of 'needing data for those games' is not correct. This is a simple filename compare :: what the system knows about (aka, the collection) vs what is in the directory ... 2 or 3 lines of code for a Programming 101 class student. LB has a ton of similar "clean-up" features. Adding 'Clean up ROM folders - remove files that are not in collection' is dead simple and complimentary to what already exists. I found a workaround... TOOLS --> Export/Copy ROMS -- this save all ROMs in that collection to a different folder Then go back to the original folder and delete ALL ROMS. Then move the 'exported' ROMs back to the original folder. Done All the ROMs in the collection will be the same as the ROM files in the folder and none of the paths have changed.

I deleted about 200 titles from LB not realizing it was not deleting the associated ROM (as it does say "not deleting your ROM - go turn on this setting if you want that) ... so now, not knowing all the files names I removed... is there a way for LB to batch remove the ROM files no longer in the collection? I thought Audit or Clean would, but it does not. thx

@Jason Carr Hi Jason, I'm a new user. I bought LB for Android in Dec 2019 just to run on my NVidia Shield... oddly never got around to installing Shield until yesterday -- and found this thread today. I read this entire thread and understand & sympathize w/ your decision. Given your comments quoted above I was curious... what about making LB for Android a streaming app : Android "Client" to an LB for Windows "Server"? This would be great for users with 'non-mobile' needs... like those of us with Android TV. Google will be launching a new Android TV device this year so the user base will likely get much larger in the coming months. With Client/Server, emulation is done on the Windows box and we use our Android TVs we love -- which are much easier to use than running a Windows PC as an HTPC + gaming system when we consider friend/family/guests that also might interact with it. I ran a WinPC with Kodi and Retroarch for a year in my home theater... total nightmare thx for considering

FB = LB ... typo, sorry about that. I thought I was explaining the 'Arcade' thing well and detailed. There is an option to select "Arcade" when you import ROMs (see attached screenshot) as well as real actual game systems (Atari 2600, N64, C64, etc) so what is "Arcade"? Under the Platforms Association (see screenshot) there are real game systems, by default... but not "Arcade". This is the disconnect and what is confusing for new users. In that list ALL systems have a real associated Platform in Eumlators... but not Arcade. Thus, a new user must create the association for Arcade manually but Not for the other Platforms, they are already there. This is confusing. IMO the fix is to simply eliminate 'Arcade' from the selection list and add MAME & FBA into the list. If the users want to create a label called Arcade, LB already allows that. Jason, if you are taking my comments in that way then I'm sorry but that is not how I see my posts. I'm not bashing anyone by asking why one item is the way it is (Arcade). "Littering" with 1, and only 1, comment that I work with coders just to let you know I'm not just an inexperienced person - OK? Don't take my posts personally, they are not an attack. Yes, I'm trying to understand the concepts as I'm new. I describing one point of confusion which no person or doc/wiki has explained : Arcade has no default Association in Emulators. All other Platforms given are real game systems and have associations built-in to LB.

Fine for totally separate systems but there are multiple versions of MAME and different ROMs work better on some versions. You are saying just for FB's use, we must have separate folders for each different MAME version and place those ROMs in that folder. For RA I just have all my ROMs in a single folder and it doesnt care, nor need, to sort by MAME version. Using Tools / Import / ROM files... LB provides a huge drop-down list which defaults to "Arcade". Without options for 'Neo Geo', 'Retroarch', 'MAME' so the user assumes that "Arcade" is correct. BUT LB doesnt have any default associations for "Arcade" So ROMs will never run (thus the fail to launch issue without an error). New Users have no way of knowing we must manually associate MAME, Neo Geo, and FBA roms as we think that is what "Arcade" is doing for us when FB defaults to it. Unless LB fixes (makes it so FB reads core/rom associations from within RA) is should remove 'Arcade' and add ALL options for ... MAME, FBA, and Neo Geo - (one for every version the user has a Core for under Emulators... this way Platform associations will be in place (which they are NOT now) correct upon import. another way to solve, the nicer way using a little coding smarts, is to read the config from RA (which is simply a few XML files) and use the rom/core associations RA uses. Thus, no need to have RA users set ANY associations at all.

@Lordmonkus oh - that sux! Strange that is missing in RA given is does know this info. I'll put in a feature request at RA but... FB is really nice but requiring users to manually edit each ROM config to tell it the correct Core is a deal breaker... cant justify paying for an app that makes some stuff easier and makes other stuff harder. I've only used FB for 2 days and already found 3 issues that could and should be addressed... 1> 'Arcade' Platform associations missing (or needs to be removed from options list altogether and RetroArch or multiple MAMEs added) 2> Fail to launch problem without any error ... no excuse on this one IMO (I work with coders for a living, not just spouting off) 3> CLI launch gap in RA that FB could but is not filling. ... RetroArch is missing a vital feature, yes.. But FB should fill this gap and since RA has Playlists which define what Core to launch for each ROM... FB could read this and auto create the CLI for the proper Core, on the fly.

@Retro808 thx for the help. Figured out the problem is LB has a 'trap' (super misleading problem without any built-in / onscreen guidance) that causes this problem. After much more searching I found other posts from users with the same problem. Hopefully we can put in a feature request to change this? Unless there is a setting I'm missing (???) to let Retroarch be the smarts and LB simply tells it to run the ROM... this looks like an oversight or problem that should be addressed. Issue: Using Tools / Import / ROM files... LB provides a huge drop-down list which defaults to "Arcade". Without options for 'Neo Geo', 'Retroarch', 'MAME' so the user assumes that "Arcade" is correct. BUT LB doesnt have any default associations for "Arcade" To a new user (one which read the wiki and several watched tutorials) assumes LB is somewhat smart with Retroarch, and should be doing this... (a) knows what association to use when it reads the ROM; since it recommends "Arcade" and there is no Platform association called Arcade it should prompt you not do nothing and not give a completely unusable debug log error (b) would have warned you that when you created the Arcade platform, on LBs own recommendation... that Platform has no association! the REAL answer IMO... (c) LB should only pass basic parms to Retroarch and let Retroarch, which knows the proper Core to use, run the ROM however it wants. *why would we not use the smarts in RA?!

Fresh install on Win10 and all games, C64, MAME, FBA, etc... all fail to run. Even when I run LB in Admin mode (which I dont do for Retro) Yesterday, I selected about 20 to test/play manually with Retroarch - core selection screen popped up, I selected the core, they all ran great. Then I try to launch them from LB and they ALL fail... literally nothing happens onscreen (debug log attached). I even tried a few that I had not ran in Retro (thus no manual core selection has occurred) and those also fail - but I can run them from Retro after selecting a core. Paths: C:\LaunchBox\emulators\RetroArch *in LB Emulators, path is: emulators\RetroArch\retroarch.exe (I used browse to select it several times) C:\roms\Arcade *have been manually importing the ROMs. Other folders under 'roms' are : Atari 2600, Final Burn Alpha, Neo Geo, etc) example of config on all ROMs in LB: ..\roms\Arcade\dkongo.zip Debug logs attached for a few different games. I see different things from different ROMs but frequently see this... 2019-04-07 06:31:21 AM FIRST CHANCE EXCEPTION: The given path's format is not supported. at System.Security.Permissions.FileIOPermission.EmulateFileIOPermissionChecks(String fullPath) Just wiped ALL LB data and started over... added a new log showing it importing 68 MAME roms that I placed inside the Launchbox\Games\Arcade ... same problem!
