Why do some games work in WINUAE and not on real Amiga?

Kenan · 29 May 2013, 15:47

For example, downloaded 3 ADFs of Aladdin (AGA) and set the same config in WINUAE (A1200, 2MB chip, same exact kickstart ROM etc), yet, in the emulator, ADFs work fine. On my real Amiga, the game simply stops loading right after the intro.

Why is this happening?

Thanks.

P.S.
Of course, this happens only with some games.

Bad floppy media?

Kenan · 29 May 2013, 16:11

^^Your guess is as good as mine. But if that's the case, why it happens on some games only? I tried both Aladdin and Moonstone AGA (ADFs) which work in emulator (2MB chip) yet, both games simply, after the intro, stop loading and the floppy driver light is just lit.

I'm using Imation floppies.

Do you have an Amiga Technologies A1200? If so, then many trackloaders won't work properly.

Edit: Does your label look like the one on this picture?

Kenan · 29 May 2013, 16:39

No, it has the classic Commodore sign/title (underlined) and under it says "A1200".

demolition · 29 May 2013, 16:42

Then they should work if your floppy and drive is working. Did you use verify when you wrote the ADF image?

Kenan · 29 May 2013, 16:48

Yes I did. And I wrote it couple of times. Specific ADFs just simply refuse to work. If it was a floppy drive issue, shouldn't it not be able to read at all and not just load the intro and then suddenly after the intro stop loading? This is the same case with two AGA games I tried: Aladdin and Moonstone.

Retro-Nerd · 29 May 2013, 16:52

Do you have an external Floppy drive connected? If yes, remove it. Could at least help with Aladdin. For Moonstone. I'm not sure if the game it 100% compatible to the A1200.

Retroplay · 29 May 2013, 16:53

Moonstone isn't an AGA game.
Have you tried the AGA fixed version ?

demolition · 29 May 2013, 16:56

Try putting this demo on a floppy and see if it works:
http://pouet.net/prod.php?which=1477
It works fine on my A1200, but that demo is supposedly very picky about having all the proper floppy signals for its trackloader, so if it doesn't work on yours, chances are some that some signal is missing from your floppy drive.
When I got my A1200 it would do the same thing, that is show the cracktro, but refuse to continue loading after that. It had a modified PC drive which wasn't done properly, but after replacing it with a proper Amiga drive, everything worked fine.

Can't download it..the web page server is down and the mirrors seem to be outdated..I'm gonna try google it instead.

EDIT:
Found it at BTTR

Kenan · 29 May 2013, 17:27

Just great..it doesn't work. The same thing as with the above mentioned titles..Gonna check the floppy drive. Any signs I should look for to see if it's a modified pc drive?

Retro-Nerd · 29 May 2013, 17:32

You should at least try the suggested AGA fixed version of Moonstone.

Kenan · 29 May 2013, 17:41

^^Ok, which one of those should I download? Too many in the list?

(Though I'm pretty sure my floppy drive will be needing a replacement)

s2325 · 29 May 2013, 17:42

f AGA = fixed for AGA

Kenan · 29 May 2013, 17:46

^^Thanks. I just realized I already have a AGA fixed version (checked the intro where it says it's AGA fixed).

Fortunatelly. internal drives are cheap..though I wasn't looking into getting one..meh..

Lord Aga · 29 May 2013, 18:00

Ohhh sure it's easy now with this fixed version of Moonstone

Back in my days

We used to play regular Moonstone! It could work for hours and then - BAM reset. Or it could crash after 5 minutes of gameplay

It was a true lottery it was.

Kenan · 29 May 2013, 23:21

I replaced the floppy drive with one from my Amiga 600 (she was unused, sitting in the closet so why the heck not). Now everything works fine and the games that didn't work before, now run flawlessly. Now, I'm pretty sure the floppy drive which came with my A1200 is not original ie. the eject button is half size smaller then it should be. It was there in plain sight for all this time but I obviously didn't pay attention.

That doesn't necessarily make it incompatible with your A1200. The reason is wasn't working satisfactorily is more probably due to dirty or misaligned drive heads.

Kenan · 30 May 2013, 00:52

Could be but it always failed to read specific ADFs/Games. I don't think I ever had a situation when it wouldn't read the game/disk it already did. It was always a specific games. I also made sure both floppy drives upon getting both Amigas were clean of dirt (used small dosages of compressed air to wipe out all the dirt. That doesn't mean it made it impossible for a dirt to find its way back somehow but..I don't think that was the case.
