Kick a 3.1 amiga 4000 back to 1.3

Wow... nearly an identical system to my A4k.  :-)

I have successfully re-kicked my A4k to 1.3 using various tools, but I wouldn't recommend it.  Very unstable -- and not much benefit.  

AmigaDOS 1.3 was a different beast.  There was no 040+ support to speak of.  Fast RAM was considered to be a Zorro2  kind of thing -- and 8 megs was a lot...  Lots of more modern features really trip up the 1.3 ROM.

Plus, most stuff that needs 1.3 will also not like things like a CyberStorm '060, 64MB RAM, etc....  And, since there is no fallback processor on an A4k, you're pretty much out of luck.  (Trying to stack together a command to go to "kick 1.3,  no cache, privledged mode, noAGA, 50hz, 512k chip, 512k ranger" isn't easy, and rarely works.)

I keep an A500 and an A1200 around for playing games when the urge arises.  :-)

hmm I remember I also have a licensed version of WinUAE with kick roms on the CD, so connecting my A500 will be a lot more work than copying the rom from cd (have two A500's and bought the original CD so there wouldn't be any problem with copyrights I think?)

No problems there, so long as you aren't running the 1.3 rom in the A4000 at the same time as in UAE.  :-)

But, honestly, I think the only way you'll get ANY joy on an A4k/CS-MKII is to run things like WHDLoad and JST to patch games up to work on more modern systems, rather than trying to run patches to make your system more backward compatible.  

If you still want to push forward, I think I had the best results trying kick 1.3 with TUDE.  But by "best results" I mean it worked a little bit, sometimes.  Which was more than the instant errors of most other methods.  I can't say I ever found a combination that gave GOOD results.  The A4000 with CyberStorm 060 is just not a very backwards-compatible design.
