You are welcome rooster, glad it helped.
I updated tutorial to include this :
Here is how your 1gb sdcard and files should look on computer before you hook up to dc. Make just 2 folders A-M and N-Z that contain 7 games each. You shouldn't make 4 folders because dreamshell won't alphabetically organize them correctly on menu, so just make 2 folders as they will be organized as such. Again put 7 games in each of the 2 folders, any more won't be visible on generic 7 line menu of dreamshell rc1.
I can hold 14 sdisos on a 1gb sdcard. 7 games each, in 2 folders labeled A-M and N-Z. It's a good idea to make volumes of these if you have many sd cards. Because if you have 14 games or 10 or whatever and put a game not compatable on, it will mess up all games. Which you will have to reformat sd card. Then drag games that worked back on it. Which sucks. Or at least have a sdcard as a "test" sd card. Then add a game that you know works on your volumes of sd cards after you tested it.
I can actually fit 24 "games" on a 2gb card. The Dreamshell RC1 gray menu is generic so you can only see 7 spaces of title info (at bottom).
So what I do is I put 7 games in 2 folders. My 2 folders are labeled A-M and N-Z and displayed on bottom of menu. Then I click or double click a folder I want and scroll through those 7 games I want to select. Hope I explained that right.
When you insert dreamshell rc1 in dc (check what version dreamshell you have, some retail sdiso and homebrews will only work with new or old versions of dreamshell) with sd card hooked up, I'll see 2 folders with 7 games in them each (because as I said ds menu is generic and shows only 7 lines).
I have many "volumes" of sdcards set up that way.
My sdiso games range on 1 sd card are entire "SDNESNester" to "NeoGeoFatalFury" to "Toyko Extreme Racer" to "NEOGEOBowling" to "DCMasterSystemEmu" to "BeatsofRage".
