Cloanto 3.x rom Amiga 500

Thank you pyrre for the explanation!

In the case of the amigakit rom, if i would like to upgrade to a newer version of workbench library (and not use the one inside the chip) how difficult that would be? It is the same procedure? adding the library on sys:Libs/?

CD32 had some whackadoodle design to use up to 2x 16-bit 1MB ROM's (total of 2MB), rather than the 32-bit ROM's like the A1200/4000.  By default it had only a single 1MB ROM chip that had both 3.1 & the custom CD32 stuff in it.   I seem to recall someone here a while back hacked their system to support both ROM sockets (and burned custom ROM's for it), but had some issues with memory addressing overlap.  Don't have time to look up the thread now, but maybe it was Cosmos?

I'd love to find out more about that.
I am enjoying experimenting with Smerf's CD32.
With the SX1 attached it does a pretty good imitation of an A1200 with an added CD drive.

I'd love to find out more about that.

There was a thread on here about it a few months ago.  I was just paraphrasing from memory.  If you look at the motherboard of a CD32 you can see where the extra ROM socket would go:

(U6B, under the sticker)

Cool, I will dig up some info of that.
Thanks.

If wb.lib is present in rom, you need setpatch (if setpatch updates the wb library), or you need some sort of softkick that uses an updated kickstart file from disk, if you have compatible hardware. Or you need to change the rom itself...

i see, thank you once again for your answer pyrre

no problem. hope you find the answers you are looking for.

I will as soon as my wallet agrees purchase the cloanto kick rom and disk set.
I just need to obtain some funds
If it works well in the 500+ i will consider doing it to the a1200 as well...

Note, the above linked workbench.library (45.132) requires 020+ and will not work on stock A600 that only has a 68000 CPU. The latest workbench.library that works with 68000 is 45.127 that comes with OS3.9 (BB2). On a small/low memort system, you may want to just use the smaller workbench.library from 3.1.
