Kick a 3.1 amiga 4000 back to 1.3

[djkoelkast]

Hi there,

for my Amiga 1200 030 I use a kickback called 'Relokick' and it works great so I can play 1.3 games on my 1200.
I do own an Amiga 500 but it isn't connected at the moment so I'd like to kick my A4000 back to 1.3 (software, not replacing chips )

Is there any software that can do that on my system (system specs in my signature)

Relokick. Or Degrader, Tude; with a ripped kickstart image from your A500 you can boot into 1.3. SKick. And perhaps some more still.

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.  :-)

Relokick won't work, it comes with a failure message.
Soon I'll be using the A500 and A1200 next to the A4000 but at the moment I don't have the space for it, I'll first need to buy a new desk ;-) a laaarge desk (as my girlfriend's pc has to go onto that desk too)...

So meanwhile I'll try to manage something for the A4000. Ripping the 1.3 rom with Transrom will that do?
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?)

I'll try to manage it again, thanks so far!

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.

 I don't know how many times I have to say this:

Get WHDLoad !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :-)

I hope thats loud enough :-)

It will solve your problems and you will never again use Floppy games! (ahh maybe 1 or 2) even 1.3 games are HD installable and compatible with AGA and the A4000

Any Questions???

> Relokick won't work, it comes with a failure message.

Relokick works OK in my very expanded A4000: CSPPC233/060,
PicassoIV+Voodoo3 in Prometheus, 3.9BB2 etc. You just have to boot from Relokick floppy and take it out as it tells "rekicking now". Just my PicassoIV flickerfixer doesn't initialize with 1.3 so I have to use the native output.
Lotus 1, which is very picky to expanded machines, even in 1.3 A500, booted OK and started to play on my A4000.
