Problems with Dreamshell RC-1

[neon]

I finally was able to boot DS 4.0.0 RC1 on Dreamcast. It was hard. I cut wires to 2,5 cm. I use tin to cover pins on my handmade SD adapter.
But finally it turned out that I don't unpack all files to the SD card.
Why? Because I use Linux, and when big cdi file was unpacking, I cancel using Ctrl-C. And this is my mistake. I though that all important files was unpacked, but they wasn't.

I would like to recommend, to split .cdi and sd folder on 2 different 7z archives.

And I also discover that my "SanDisk SDHC 4GB class 2" sd card works OK with RC1.
I tried also "SanDisk Extreme III 1GB" and "Esperanza SDHC 4GB class 6" and bough works fine. But my crappy "HTL 128 MB" don't work. My adapter works fine without capacitors.

As few people mentioned 50 hz mode don't work correct. The screen is shifted down. Now, I use 60 hz NTSC mode.

I have also 6 questions:
1) I noticed LBA window in ISO Loader. How to use it?
2) How to use virtual keyboard? It's still too small.
3) How to boot games with LBA 45000 copy protection?
4) Do we still have to change LBA to zero?
5) How to go back to Dreamshell menu from game?
6) SWAT why you don't add your tested games from RC1 to SDISO Compatibility thread?
