My Mister works perfectly with NG roms (Darksoft set) loaded from SD, but if I put them on external USB (USB 3.0 NTFS 2TB Toshiba Canvio Basics HDTB420EK3AA via external USB 2.0 powered hub) I can see "games\Neogeo" on the USB, but if I click a game folder nothing happens (looks like the folder is empty).
If I navigate back to SD and launch a game the rom is loaded but graphics is garbled (look like video is missing a "layer", like no sprites, garbled backgrounds and such).
If I power off Mister and remove the USB drive, everything goes back working fine from SD.
I have a 128mb memory module and memtest is ok @140.
I ran "update" and "update_all" scripts with no benefit.

Other cores works fine both from USB (i.e. MegaCD) and SD (i.e. Arcades).

Any hint? Is NTFS the problem?

Ditch NTFS and switch to exFAT. NTFS is case sensitive and causes a lot of problems, don't ask how I know. For example for NeoGeo the name of the folder should be NEOGEO but the update script creates it as NeoGeo. At one point I had NEOGEO and NeoGeo directories with NEOGEO containing the roms and NeoGeo empty. I looked at the drive under Windows which sees the 2 directories but when I open NeoGeo it had all the roms and backing up one directory the highlighted directory was NEOGEO.
When using a USB drive do not use ext4 or NTFS but stick to exFat, it will save you a lot of headaches.

Thanks, I'll try and report.

Ok,
I formatted in exFAT, and put:
-a game (bin+cue uncompressed folder) in TGFX16-CD folder; source: Redump
-a game in uncompressed folder into NeoGeo folder; source: Darksoft
-the same game as above in single *.neo file format into NeoGeo folder; source: everdrive Mister Pack

Result:
-selecting the game folder it looks like it is loading then get a "bios not found" error
-looks like the folder is empty
-games load but graphics is garbled

If a move the folders\rom onto SD, changing nothing, everything works like a charm.

Ideas? I'm clueless. ^_^'

I ran into a similar problem with a CIFS share

I found that I had to have the exact same setup on the share as I had on the SD card. Ie the Xml files and the bios files on the share and in the same relative directories or nothing loaded. As soon as I had the same set up on the share it worked. This may help you on your USB issue.

That worked, thanks a lot!
