Problems with Dreamshell RC-1

[B00daW]

Hey, first off I'd like to say a few things... I'd really like to give my thanks to the DC-SWAT community for creating this product. I'd also like to thank you all for creating an English forum so that other parts of the world can enjoy it.

To give a little background about what I have and what I have done:

I have an unmodified US NTSC-U Rev. 1 Dreamcast. I have a SD serial loader bought from Taobao. I had to use sandpaper to sand away a bit of the plastic in order to create a snug fit. It connects fine now. I have a Class 10 Patriot (US made) 32GB SD card. I have tried Dreamshell 4.00 RC1 Bootloader and Dreamshell 4.00 Beta 4 SD Bootloader. RC1 boots to the menu but when I select "Boot from SD" the DC either reboots or hangs on a black screen. My SD card was recently formatted and has the DS folder in root. When I use Dreamshell Beta 4 I am able to boot into SD and load files without issues. My only problem is the lack of compatibility with ISO images. I am also considering to overclock my Dreamcast to a save speed without need of another fan.

Questions:

- How can we help in order to increase SD compatibility with >RC1 releases?
- How can we help to increase with SDISO boot compatibility?
- Can kernel tweaks help with SD access speeds for high-class SD cards? Are any hardware modifications possible?

Since the Dreamcast may be a "dead" console it's the perfect "new-gen" console to play games with good graphics and sound these days without much legal repercussions. I hope this project progresses further.
