How can I include Iso Loeader 0.7 in Dreamshell 4 RC4 Boot Loader image?

Post#1 » Thu Feb 11, 2021 11:05 am

I plan to follow below tutorial in order to try hdd mod,
http://www.dc-swat.ru/forum/thread-2367.html

But As far as I know Even though I succeed to hdd mod,my dreamcast still need to boot off CD-R ,So I'll download below download link of DreamShell Boot loader and burn it onto CD-R.

http://www.dc-swat.ru/download/dc/ds/4. ... _Loader.7z

But I heard that ISO Loader has up to date currently and it is very decent compatibility but The last update of DreamShell 4.0 was 4 years ago(RC4) ,So its ISO loader ,which is included in DreamShell 4.0 RC4, would be very obsoleted version.
I know that It would be impossible to load ISO Loader from HDD, So I want to include up to date version of ISO loader in boot Loader image of DreamShell 4,0 RC4.
I really want to know the way how to include Iso Loeader 0.7 in Dreamshell 4 RC4 Boot Loader image.
Any reply would be appreciated.

write to CD bootloader
download DreamShell from https://github.com/DC-SWAT/DreamShell/tree/master/build
unpack folder "build" to your HDD
rename "build" to "DS"
download loader 0.7.0 and unpack to /DS/firmware/isoldr/

If you name it as ide.bin isoloader select it via auto in preset.
Else name the 0.7.x simply with a number like 1.bin for exemple. And you'll can call it if you put 1 as entry for loader.

Thank you very much for your reply!
I finally succeed to hdd mod and I downloaded zip file of all of DreamShell files in GitHub, and extract all files and sub directory in the directory of build to HDD, then I rename build directory to DS
And I extract downloaded file of "ide_0.7.0_b2.7z" to D:/DS/firmware/isoldr, then I wrote dreamshell 4.0 RC4 boot loader to CD-R with imgburn and boot it off from my dreamcast,It seems that My dreamcast successfully connected with HDD and I can get into all of DreamShell's sub menu. But when I tried to load ISO loader and select files of games(.GDI,.raw,.bin) an error message displayed.

DreamShell ISO from IDE loader v0.7.0
Not supported sector size (2352)
Use optimized GDI or ISO
Failed!

Is there any way to convert sector size of bin or raw extension files in order to load it on ISO loader v0.7.x?

bin tracks don't supported in loader 0.7.0, only gdi with iso tracks
use gdi batch optimisator or download games from this thread

I have applied gdi bach optimisator to each of gdi image,But when I tried to load them with Iso loader v0.7 It display another error message..

DreamShell ISO from IDE loader v0.7.0
Initializing IDE...
LBA28 HDD don't supported
Error can't init IDE.
Failed!

I have some IDE hard drive which capacity is 40GB and 80GB and 120GB..
Do I have to purchase another IDE had drive which capacity is larger than 137GB(LBA 48 HDD)?
And Is there no way to use any of my IDE hard drive in ISO loader v0.7 all of which capacity is smaller than 130GB?

Thank you ver much for your reply.
I have connected my excelstor 80GB hdd to dreamcast and I found that It really supports LBA 48..
I got confused that it is impossible for 80GB capacity hdd to supports LBA48
