Custom Kickstart ROMs

[d3cka2d3pwood]

Hi, can anyone here make custom kickstart ROMs for the Amiga 1200?

Specifically after 3.2.2 with HRTmon built in but not sure if this is possible due to memory limitations.

If 3.2.2 is impossible can anyone here do it with 3.2, 3.1.4 or 3.1?

I saw this on YouTube [ Show youtube player ]

Try using Romsplit and Remus + WinUAE to see if it is possible.

If you have an accelerator which supports MAPROM you might be able to get it to remap a file rather than the physical kickstart (it would run faster too)

You don't need wizardy if you use Remus http://www.doobreynet.co.uk/beta/

Looks like Remus beta can do OS 3.2.1...has anyone tried with 3.2.2.1?

Remus doesn't support 3.2.2/.1

I had to use capitolline rom tool to pull it apart.

However comparing 3.2 with 3.2.2.1, Only thing that appears to have changed in rom is kernel. All other modules appear to be same. I even checked all the modules from the module disk.

I will have to contact Doubrey, see if he can update Remus for latest kickstart, like before. I love remus, awesome tool.
Once updated, it will be easy to make 1MB rom with all missing stuff added back to rom and extras.

Thank you all for your responses
I will check out Romsplit and Remus in WinUAE first however not sure how they work. I've just checked out the link but still non the wiser lol.
Is this a software trick? Does this trick only work after you have loaded into workbench?
I want to use HRTmon when booting a game from the kickstart screen using a floppy and not from WHDload/from workbench.

I have an ACA1233n so can try MAPROM too but I have no idea how to use that either.

I have only just upgraded to 3.2.2.1 recently from 3.2 and it fixed a bug a had with right click options freezing in workbench.

Windows tool Capitalone is dumbproof alternative to Remus. Even I managed to build custom 3.2.2 ROMs with it. http://capitoline.twocatsblack.com/

Really, Im not exactly stupid and I found it very confusing.
Ended up, using it to pull rom apart, then used those modules in remus.

You can also use romtool to build ROMs

Would Doobrey be willing to opensource Remus? Or alternatively accept a bounty? I always liked using that tool in AmigaOS natively

I can't answer that question but amitools I linked to above is open source. Amitools (Vamos) is used to build parts of OS3.2.

Christian is a nice guy. I asked him about Blizkick modules support which he promptly added.

Problem is, it uses the Splitrom DB from Remus that doesn't support 3.2.1 +

If you do all the work for Doobrey (i.e. get him the modules that have changed for 3.2.2+) and the official ROM if one exists. Perhaps extract the info from capitolline.

I think he would fire up his development environment again to get a new database.

He did it for me several times in the past to add support for special ROM builds.

I asked him for 3.2 support, which he did. Just haven't spoke to him for a while. As I said, will try and contact him.

i managed to make a 3.2.2.1 rom for a1200 with hrtmon included using the Capitalone tool. I had to remove a couple of modules to fit it into 512k. I had to remove scsi.device and gadtools.library which isnt ideal but was acceptable for a proof of concept.

Basic steps are

1.copy the kickstart 3.2.2.1 rom and hrtmodule into the roms folder under Capitoline.
2. load capitoline
3. click new rom button on the loaded roms page and create a 512k rom with f80000 as the base
4. on the files page expand the kickstart rom in the tree and select the modules from the rom. right click and 'copy library to rom'
5. select the hrtmon module and do the same copy library to rom
6. on the loaded roms tab select 'save rom'

Better to make 1MB rom. I did try with Capitoline, 512kb and 1MB. Niether worked even when using 1MB script. I do keep coming back, as newer versions are released and trying again. As I said, ended up using Capitoline to split rom 3.2.2.1 then use remus to create 1MB ROM, which worked perfectly.

I don't fully understand the process for creating/using 1mb ROMs but I was not able to make that work at all

Here guide.

You would need to basically create two 512 kickstarts.

First one would have exec first, second needs to be 1MB_ROM from Blizkick archive.

Second needs to have romheader and DummyCDstrap first from Remus archive.

Thanks @Phantasm I'm struggling with other methods but I think I'm nearly there with the process you described when using Capitalone. What is the hrtmodule file that you used? Where did you get it from, what is its file extension and size please?

[Phantasm]

i initially did it with the one linked in the video but i also created my own from the latest hrtmon using the same process as in the video (attached to this post)
