dreamshell's Issues

set5v1.001.bin GD-ROM BUG

I recently flashed this version to my DC and I lost the use of my GD-ROM. Any disk I put in just hangs on the initial read. If I boot the DC with the disk in the drive it hangs on boot logo. V01 DC was running perfectly with region free bios chip on JC and DS bios before this. Without the use of the GD-ROM I'm stuck on this bios with no way to load DS to flash a good firmware.

Working or not ?

So i have burn it and lunch it on my dreamcast, but no way to lunch the sd card ?
Uploading IMG_2194.JPG . . .
Uploading IMG_2195.JPG . . .
img_2196

so i can lunch dreamShell, what is wrong ?

Can't build DreamShell

Hi,

I'm trying to create a Docker-Container to build DreamShell within.
I already created a container including the KOS-Toolchain, which works just fine.

Based on that container, I build the DS-Toolchain & libs, patched & rebuild KOS. Every Makefile exits with Returncode 0. See the Dockerfile for details. [0]
I forked DS to fix KOS-Patching & change KOS-Location in Makefile. See [1] for details.

But I still got a problem linking DS:

Trying to build on debian, getting errors about gcc

Heya,

not sure if anyone even still reads this. I tried to compile everything as written at https://github.com/DC-SWAT/DreamShell

Problem 1: it wasn't written, that I need the lua package, which I have installed (maybe add it in the first two apt-gets?)

Problem 2: I'm at the point of the list where I should make source ./environ.sh, but:
grafik

I have downloaded and extracted the gcc 5.2.0 from the webpage, but inside are only Windows executables? How can I compile with them?

Trying to build with the most recent github repository because when I try to dump Sonic Adventure 2 or Ecco with DreamShell 4.0 RC 4 CDI Image the Sega Logo never even starts becoming blue, the whole DC hangs and on the SD disc I only have a 0 byte file.
I was able to dump Sonic Adventure 1 with it. I hoped, the most recent repository version might have a different outcome.

Where's VMU Manager App?

I downloaded a build folder from this GitHub page and renamed build folder to DS folder and place it to root of SD Card. After boot to DreamShell. VMU Manager App is not there anymore!

Can you please add VMU Manager back in next build version on GitHub? Or you're just waiting until the next major update version on main website?

Failing to compile toolchain on macOS High Sierra

I followed all of the instructions in the toolchain Makefile (installed gcc 8.1.0 and exported path correctly).

Patching fails on one file for some reason, one of the KOS headers but I was able to easily make the patch changes manually.

Then running make build compiles for a while then I hit this error:

../../../gcc-7.1.0/libgcc/libgcc2.c \
	  -fexceptions -fnon-call-exceptions -fvisibility=hidden -DHIDE_EXPORTS

Please submit a full bug report,

Any ideas? I see that the macOS toolchain build instructions were literally added days ago by @yevgeniy-logachev, so I assume it should work.

isoldr doesn't compile
