Help needed with Cannon Fodder HD on Minimig

Gaula92 · 24 December 2010, 15:53

Since Cannon Fodder ADF's can't save game because it seems Minimig isn't compatible with it's custom disk acess routines, I'm trying different HD versions (not WHDload, lots of os-swap here with 2MB RAM).

So I have this great release by Triangle. It DOES work perfectly on UAE with 1.5MB chip, and a plain 68K. It also works on my real 1200. But it can't save or load on the Minimig (black screen, music keeps playing...)

I need someone with some experience in finding out what could be happening, so I have uploaded the release to The Zone. So if you can try it on a Minimig or at least tell me what does this game do when saving or loading...
The file is named: CannonFodder_Plain68k.zip

Thanks!

It doesnt need testing on a MiniMig it wont Load/Save on 68000 but will on 68020 maybe someone can tell you why this particular part of the game only works on 68020 - Hope you get it sorted

Gaula92 · 24 December 2010, 16:35

No. It DOES save on plain 68K. A 68020 is not needed for this version to save:

Retro1234 · 24 December 2010, 16:45

OK

I remember telling you it wont Save on 68000 but after seeing your picture I can see it fails to Load/Save if Cycle-Exact is ticked - Version off WinUae im using at moment always starts cycle-exact - anyone know why? WinUae has always got cycle-exact ticked.

Maybe this holds some clue to what the problem is.

Gaula92 · 24 December 2010, 16:59

...no, the game also saves with cycle-exact 68K:

Retro1234 · 24 December 2010, 17:08

I meant under Chipset - I cant test right now but its deffentley just shows a black screen like you describe on the version of WinUae im using with Cycle exact ticked under Chipset

Gaula92 · 24 December 2010, 17:09

Ok, I can now replicate the problem in UAE: Cycle-exact chipset emulation makes it impossible to save or load. It exhibits the SAME behaviour as on Minimig.
So I believe Minimig's chipset is more or less cycle-exact by now, and that's why the game can't save.
Thanks for your idea, Boo Boo!

Would it be possible to fix this small problem? How?

Retro1234 · 24 December 2010, 17:18

Yay we got there in the end, I thought I was going Crazzy - Again hope someone knowlegable helps you out

I dont want to test now because its Xmas but ill test some time on my Real A600 but because Cycle-Exact causes Load/Save to fail -Does this impley it will fail on Real 68000 hardware.

edit:Minimig YQ091224 firmware -- massive rewrite of Blitter (very cycle exact - improves compatibility a lot
Dont know if different firmware makes any difference

Gaula92 · 24 December 2010, 17:43

Maybe, but going back to a VERY old firmware just because it had worst chipset simulation makes no sense at all.

Gaula92 · 06 April 2011, 21:09

I'm resurrecting this somewhat old thread as I've been unable to save my game in Cannon Fodder on the Minimig.
Is there someoune out there who uses, let's say, an Amiga600-HD who has an HD working version that's able to save on a plain 68K?
Or... Is there any way to avoid the flickering/music stalls with the WHDLOAD CF in a machine with only 1.5MB?

thanks once more

dlfrsilver · 06 April 2011, 21:13

Maybe the disk part function of the minimig ?

Gaula92 · 06 April 2011, 22:00

The ADFs? No, Cannon Fodder uses custom disk access code to load/save wich doesn't work on the Minimig. That's why I'm trying different HD versions.

dlfrsilver · 07 April 2011, 00:48

I'm talking of a bug in the core

Gaula92 · 07 April 2011, 15:21

Well, it's not a bug in the core really: It's just that Minimig can't handle the special, oversized ADF of a Cannon Fodder savedisk.

dlfrsilver · 07 April 2011, 21:54

The special "oversize" is not that special since it's written on a standard drive.

it's an MFM format, with a size of $16c0 per track.

Gaula92 · 08 April 2011, 13:51

Every ADF I tried in the Minimig as a Cannon Fodder savedisk didn't work. Most of them were oversized adfs... why they are bigger, I don't know. But they are

Do you have a Minimig there?

Gaula92 · 30 April 2011, 14:11

I'm bringing this up again as Cannon Fodder is the only game that doesn't play well on my Minimig (among all the Amiga games I've tried so far, and they've been a lot!).

@dlfrsilver: do you have a savedisk adf wich works on the Minimig?

@StingRay: did you take a look at the HD version in case it can be easily fixed for plain 68K amigas?

thanks

Gaula92 · 01 May 2011, 13:36

I've found the version you uploaded to THE ZONE, dlfrsilver. Thanks!
However, it has a 2.2MB adf wich isn't handled by the Minimig.
Isn't there any other alternative, like changing where the disk version stores the saved games?

Why not use WinUAE to create a save adf 880kb.

Gaula92 · 01 May 2011, 17:30

I tried that on the past but the resulting image didn't work on the Minimig. Does it work for you?
