DreamShell v4.0.3 Release

[Ro Magnus Larsson]

hi: I am organizing my folders and I need to do in DS the following:
1-How to put covers to folders where there are many ISOs/GDIs (for example "Atomiswave", "NEOGEO CD") in order that it can shows the Atomiswave cover when we click o lay the cursor in "Atomiswave". In RetroDream we could do it just putting inside a random gdi file like "Atomiswave.gdi" but in Dreamshell it show error and it does not even allow you to enter the folder and play.
2-When entering to change a new game Presets It does not stay saved, if I reboot DS or play again the preset comes back to the original state again
3-Is there a roq-mp4 Videos preview mass converter for DS?

sorry if anything of this were answered at some post
