Bug is present here.

Thanks, next one. If the bug is still present then the fix won't be easy (i.e. no more test slaves today).

Bug is still present , is that fix the start of this bug ?

Yes, the game copies data to an invalid memory location. However, as soon as that's fixed the bug occurs which is kinda strange (maybe some "mirror mem" crap or smth). Some debugging sessions ahead, "hooray". Thanks for testing, it was the last test slave for the moment since I will have to debug at home.

No problem , will be present when you'll need as usual

OK, here is one last test slave

If the bug still occurs I am out of ideas for the moment.

Bug is still here.

StingRay · 21 January 2010, 13:10

OK, then I will have to do some serious debugging at home. That was definitely the last test slave for the moment.

Ok , just a question , as i'm testing under a 68000 machine and your fix was done for biggest ones , is this bug present in Big configs ?
I'm asking that because with the last slave working (just before the one in whdload.de) , all is fine in 68000 machines.
Perhaps should i test under winuae with a big config ?

StingRay · 21 January 2010, 13:49

The bug is present on your 68000 too, you just won't ever notice it since the game seems to behave normally and WHDLoad will not complain either (due to missing MMU [=Memory Management Unit, WHDLoad uses that to detect illegal memory accesses]). It is, however, a serious bug that needs to be fixed because writing to "random" memory locations is not nice. It was f.e. one of the reasons why I had a lot of problems to create the patches for ManU PLC/The Double since there is some incredibly stupid memory checking/trashing routine in these games too. =) (trashed memory meant that I had to reboot after testing any slave because the game corrupted memory and the Amiga crashed after quitting WHDLoad)

Ok , thanks for the explanations

StingRay · 22 January 2010, 09:55

I have fixed this problem, was actually 24bit related (i.e. game works OK on 68000, no bug there), game used sign bit (31) in the address register as some flag, 68000 does not care, 680x0 does. Fix is like this:

Code:

	move.l	a1,d7
	and.l	#1<<31-1,d7
	move.l	d7,a1

The install will now require 1MB Chip Ram for obvious reasons. I'll create updated install package today or tomorrow.

lolafg · 22 January 2010, 17:17

Great , you found it , nice work Sting

Incomparabile · 22 January 2010, 23:04

Great job StingRay, I loved this game and now I'm going to play with your version.

SuperNashwan · 31 March 2012, 17:42

Does anyone have a preinstalled version of Manu Europe and PLC? It would make me very happy!

Edit: Forget that! Just found the EAB fileserver...
