Thx will check that out. No idea why the .238 wouldn’t work for me. Tried a few more. Same issue. Then just copied my old ones over those and they started working again.

Sadly this CHD set and rom set was from PD. CHDs of that set (1TB worth) at least three that I tried didn't work from the .283 set. kinst, kinst2, gauntleg. Not sure if i use the handful of old ones I have or just try an older set of CHDs from PD? Wanted a complete set this time around. Interesting on the mame plugin. Will definitely look at that.

Well I just tried an older copy of the CHD in question and the game worked!!!? So this golden standard source isn't so golden. Complete is apparently an misused term. May need to try a different set since the complete merged .283 doesn't work with .283 rom set.

I have this in the MAME ini. Seem alright? "roms;D:\LaunchBox\Games\Arcade;D:\LaunchBox\Games\Arcade" When I try a CHD game from Launchbox screen blinks black then kicks back to launchbox. If I try the same game from the MAME emulator itself I get an error saying " game.chd DIFF CHD ERROR: Invalid parent Fatal error: Required files are missing, the machine cannot be run" These are matching complete sets of .283 from a reputable famous source.

Thx for the quick and detailed response JoeViking. I did add the CHD folder to MAME itself via the UI (also tried the ini) and the CHD folders are in with the roms as described. I’m not sure about that Launchbox command line parameters though. Will have to check. MAME itself does not run the CHD games either so it’s likely not a Launchbox issue. Will double check all though and get back. Just wasn’t sure if I was chasing my tail and needed to match a merged to merged CHD set or a non-merged to non-merged CHD set?

I have been setting up a new clean Launchbox install on my new system. Put the full .283 MAME unmerged set on. Could not get it to run at all with Retroarch and libretto cores and I don’t know why. Problem for another time. So instead got it running with just the standard MAME install. All works fine but I can’t get any of the CHD games to run. Does the CHD set need to be unmerged to match the unmerged roms, as my current CHD set is merged? Should I change to a merged set to match the merged CHD set?

Yeah I really wonder about the Xeons. Eventually I plan to put it on a much simpler consumer grade gaming rig in my future game room. It's just Big Box that has that feel...all games work as expected.

Read that thread and have tried those items. Have 32 CPU cores (Dual Xeons with 8 cores each 16 hyper threaded), 32GBs of ram, and 2x 980 Ti's.... Launchbox barely touches it load wise. It's a heavy lifting workstation for Color Grading and 3D rendering. I have removed all unnecessary services and processes. I only use windows firewall. Also have let it sit for hours on end and gone through and made sure every image is opened by hand and cached. Performance the same. I suppose I could try a clean boot forcing everything off but I doubt that will change anything. I'm beginning to wonder if it's a Xeon thing vs. a consumer grade cpu. I have even tried limiting the affinity of Big Box down to 4 cores. Seems a little bit more responsive but that could just be in my head. Looking for any other solutions. Launchbox and the roms are currently on my slowest drive in this system. Just a regular WD Black 1TB. I plan to put a 1TB Samsung M2 960 Pro in early January and migrate the Launchbox setup to that. At 3200MBs that should clear up any IO issues though I doubt that's what this is.

For some reason Big Box is just very sluggish in it's animations and response to input. Coverflow is the worst culprit regardless of image quality settings. The sounds of changing game selections seem to be in sync with the input commands but the animations are dragging way behind and seem to be well under 30fps. However even down to the text list view (the fastest mode) there is some hesitation especially if you rest a hair to long on a game and let the imagery and description load. Moving your selection in the middle of that transition always causes sluggishness and frame rate reduction. This sluggishness gives an overall taxing feel to the whole interface....like the computer is struggling with something. I do have a massive collection indeed, however I also have a massive computer and this sort of performance should not be the case. I have tried disabling animations, details, and transition types... still the same performance. Any suggestions or help would be great! Attached some system specs below. As you can see a very high end system so I'm not sure what's happening.

Thanks for the quick response and openness to new additions! Totally buying your software today. Thanks again.

Looking into using this as my arcade frontend on my HTPC. Looks great. Before I purchase though I'm curious if there is a way to hide the mouse cursor in Launchbox? I'm a fan of the Launchbox interface and not entirely sold on the layout of Bigbox yet. I'm using a joypad to move around and make my selections, however when I open a game and then exit out back to the launchbox interface the mouse cursor is reset to the middle of the screen. This causes the mouse to hover over a game and highlight while I am moving the actual selection around with the joypad. Annoying and distracting to have the two selections running at once. Anyway to disable or autohide the mouse cursor so this doesn't occur? Or is this something that may resolve itself with the premium one and features like minimize and maximize after entering and exiting? I think it is caused by the emulators switching to a lower more appropriate fullscreen resolution for emulation then bouncing back. Thanks.
