Creating custom kickstart

[mfilos]

Since it needs to fit 512KB I assume it's meant for A4000...
I made some time ago a custom Kickstart for A4000 that contains every module from Kickstart 3.1 plus the following updates/additions:

- Exec 45.24 (instead of 40.10) from OS3.9 BB4
- BootMenu 44.7 68020 (instead of 40.5) from OS3.9 BB2
- Console.device 44.10 (instead of 40.2) from OS3.9 BB3
- Datatypes.library 44.48 (instead of 44.47) from OS3.9 BB4
- Filesystem.resource 45.10 (instead of 40.1) from OS3.9 BB2
- FastFilesystem 45.16 (instead of 40.1) from OS3.9 BB4
- Icon.library 46.4.220 (instead of 40.1) from OS3.9 BB4
- RAM Handler 44.24 (instead of 39.4) from OS3.9 BB3
- SCSI.device 44.2 (instead of 40.5) from OS3.9 BB3
- Shell 45.27 (instead of 40.2) from OS3.9 BB3
- Trackdisk.device 40.2 (instead of 40.1) from OS3.9 BB4

Everything fits just fine on the 512KB Kickstart ROM except:
- Workbench.library 45.131 (instead of 40.5) from OS3.9 BB3

... which can be easily be put on LIBS: of your Hard Disk/Floppy Disk and run just fine.

I don't understand what do you mean by not wanting to loose functionality. Workbench.library AFAIK is only used for Workbench and not Games/Demos etc.
Since booting workbench means... using a floppy disk or hard disk... I don't see anything wrong by loading the workbench.library from the LIBS: folder of an hard disk or floppy disk accordingly

@ecs
The installer does all things automatically and just tells ya what modules to insert via LoadModule and how to use the SetPatch declaration correctly.
Apart from that you can easily get the files per folder of the BB3/BB4 installation and put them to the required folders. The whole folder list on BB3/BB4 archives is very nice organized and easily understandable on what do to... even without having the installer!

I most of times check the changes per version change and manually install what I want from these archives.

@Heiroglyph
This is exactly why I used this solution.
