Drive Code C128D N0SD0S Scanner bug.

Recently Nostalgia released Legacy of the Ancients.
Legacy of the Ancients +8DIR

The program used to scan the IFFL file refuse to
work on a C128D. I got this error report from someone
in USA, so I did a test on my own C128D.

What happens is:
Installer searches for the iffl file,
then it locates track+sector of the iffl file.
At this point this text is displayed on screen.

N0SD0S V1.2

SCANNING

73, CBM DOS V3.0 1571,00,00

Then scanner get installed in the 1571 drive. Scanner now
searches the IFFL file and you can hear the drive is working
as it makes a click for each track it moves to.
But then at the end of scanning everything freezes,
drive is spinning forever and the led is on.

I tried the same game disk on my c64+1541 and it
works fine. I tried not messing with the $1c07 timer.
I tried with and without fastload cartridge on my c128D.
But I get the same bug each time. Some have said i Have a bad VIC chip, but the VSP scroller in the n0s intro works fine for me.

I am not sure if its the C128D or the disk drive that is causing the problem. I wonder if anyone of you can help
me by verifying if it works or not on these setups:

1) C128D.
2) C128D but run the game from a external 1541(II) drive.
3) C128 + 1571
4) C128 + 1541(II)
5) C64 + 1571

Please post your report here.
Also, if you have any other suggestions to what
the problem might be please post here.
Thanks!

C128 + 1571   : game loads
C128 + 1541-II: game loads
C128 + 1541   : game loads
C64 + 1571    : game loads (even using Final Cart. 3)

[edit]
I thought my C128D was broken, but the C64 mode still works, so:
C128D + internal: game loads (!!)
C128D + 1541-II : crash *)

*) with internal 1571 on, loading from external 1541-II, the light of the internal drive remains on and the game crashes with EOA logo. The DOS versions on the screen is 1571, while I load from 1541-II. Mind you, there's a device-# conflict...

I'll try this when I get home again. Sounds like the same problem that other loaders also seem to have :(

@GRG: yeah, it loads perfectly. I hear music and stuff :)

Have you tested between the two models of C128-D: plastic case & metal case?
I've got a plastic case...

[edit]
Oh, btw, because I forgot to press C= key one time, I found out the C128D also works in C128 mode... it was broken before (black screen)! So thank YOU for that :-)
It doesn't work with tape, though...

My C128D is a plastic case. Joyport #2 doesnt work though..
Could be its broken after all..

Hope someone else with a C128D can give it a try. :)
For a third opinion you know..

Hey Glenn,

works fine here on my C128D-CR (metal case) and C128D (plastic case) with the internal drives. If I can be of more help, drop me a line.

I tested it on my C128D (Scandinavian, plastic case) and it played fine with the internal 1571, both with and without AR6.

I also tried using 1541-II as #9 but it didn't work, I once got it to the EOA logo but usually it jammed saying 'scanning'. This drive sometimes acts a bit funny so it may be due to that.

With a breadbox C64 + 1541-II it worked ok.

I had some problems with loader and my C128D (metal case) sometime before, especially when I was playing around with dreamload, which seems to be quite similar to Nosdos, I think. With one of the latest updates of dreamload, even my C128D seems to work... ATM I can't test the game since I was moving houses, but maybe in a few weeks... ;)

Ok, so there must be something weird with some 128D's and DCR's because it worked perfectly on mine as well.

Very strange!
