WHDLoad Installation Problem

[sim085]

Hi,

I am installing WHDLoad. I had already done this in the past but I thought of trying this again. I am installing WHDLoad from WinUAE at the moment.

The problem is this; When I set the processor to type 68000 WHDLoad fails to install. However if I set the processor to type 68020 (or higher) I can managed to get WHDLoad install. After installation I can set the processor type back to 68000 and games work just find (example: lemmings).

Does this mean that on real amiga hardware WHDLoad would need a 68020 processor to be installed?

Regards,

No.
A bare 68000 is enough for installation and running at least 50% of all slaves, only if you have enough RAM (1Mb CHIP and 2Mb Fast is a working config for A500). That's a functional setup, not an ideal.
68020 would make system more responsive in terms of overall speed and it would allow all WHDLOAD games to support quiting back to OS.
 
Can you quote error message ?

According to the WHDLoad manual, the minimum requirements are a 68000, Kickstart 2.0 and 1.0MB of RAM. Some games will require more though.

Here is the error I get when processor is set to 68000:

Installer
Program failed (error #80000003)
Wait for disk activity to finish

If I set processor to 68020 (or higher) I do not get this error!

Which kickstart rom image are you using?

Which kickstart rom image are you using?

Kickstart 3.1 but if you want I can test with Kickstart 2.1 as well (I do not have others however).

You have wrong version of Installer (compiled for 68020).

Thank you for that. I downloaded my installer (WHDLoad_usr.lha) from WHDLoad website, that is here: http://www.whdload.de/. I did not know there where different versions for different processors.

Could this mean that even though when I changed the processor back to 68000 lemmings works fine, I could find games that actually do not?

[Lockon_15]

Yes, you could.
Some WHDLOAD installs are compiled to run at 020 as minimum, some require rare 010 for so called VBR support which you cannot get on plain 68000.
I have found at least 2 games from my personal interest (Amiga Karate, F/A-18 Interceptor) which failed to run on configuration similar of your own. The issue was resolved as slave/install author was kind enough to re-compile stuff compatible for 68000. However, I find that a rather exceptional case, not a common among a niche of WHDLOAD slave/install authors.
 
At the end, at least you got one more reason to start over getting A500 accelerator.
Or switch to A1200 which is, hands down, a WHDLOAD gaming champ, right from bootstart.

Hi, I think I just found such a game! I tried to install Colonization WHDLoad version. When I try to start the game I get an error that this program needs at least a 68020 processor.

I do have the original version however installed on the real amiga hardware which only has a 68000 processor. Does this mean that if I want to use the WHDLoad version then I'll have to recompile it?

[Lockon_15]

Yes, but honestly I don't see you doing that alone.
That's way over your league (me included!) and your best bet would be to contact author if he can reconsider recompile for 68000.

[sim085]

I may try to do that. Not because I need it (I have the original disks which work fine on the 68000). It is more because in my opinion this game worked perfect under a 68000 processor. However maybe it needed a more powerfull processer when working under WHDLoad.

However isn't one of the goals of WHDLoad to make games work the same on all the different processors and kickstart versions?

I do really admire your determination, even if it's bound to fade abrupty when you actually realize what WHDLOAD slave writing is all about.
 
Back to the topic, WHDLOAD does need some extra system resources since it's a OS wrapper. Games run on same hardware would suffer some speed loss, but I guess on plain A500 things are slow as default and thus little affected.
 
WHDLOAD tries to allow/recreate same or near same experience (with respect to original), but that's only an attempt being constantly improved from each new release. There are known limits (it won't work under Kick<2.0), and know issues (68040 is a bad WHDLOAD host choice, many games need additional tweaking).
In fact, I'm aware for few games which are too fast on my 030, but that can be handle by smart slave option set.

There is no shame in trying and failing (which is what will most probable happen). Just another question. To install the new installer I need to just replace the files inside my Workbench directory?

[Lockon_15]

I might been a bit over the line.
Sorry for that.
 
Extracting file "Installer" from archive into "C" drawer would be enough.
