I have used old/new/DD/HD floppies and the writes WORK!. It doesn't appear to need new and DD disks in order to successfully write images as some of the discs i have used are old IBM formatted disks that i got from work which are about 10 years old and had old data on them. Most of the disks i have are mixed brands so overall, VERY happy.

the list is long of what i have successfully copied... heres a sample

dragons Breath
Hybris
Zoom
Gunshoot
Leander
Battle Squadron
Adams Family
Alien Breed Tower Assault
Capone
Chase HQ
Defender of Crown
Dragons Lair

Denaris
Double Dragon 2
F29 Retaliator
Great Giana Sisters
James Pond
Lemmings 1
Lords of Rising Sun
Magic Pockets (loads different from original, it struggles)
Obliterator
Paradroid90
Parasol Stars
Rainbow Islands
Rick Dangerous (Both 1 and 2)
Silkworm
Silly Putty
Shadow of Beast 2
Smash TV
Space Ace
Speedball (Both 1 and 2)
Swiv
Sword of Sodan
Turrican (I, II and III)
Wrath of Demon

Awesome!

And the game Awesome too lol

Glad, you are happy with it

It has taken a lot longer than we anticipated - we could have released a "crappy" version a long time ago... but decided not to.

As for GnG thanks for bringing that to my attention.
Apart from the fact the it is the first release of the game and is missing data (!) it used something either deliberately or coincidentally, that makes writing very hit and miss - unless you verify the track written, and retry if it failed.
We have a later release of the game dumped now, and this "feature" is gone, so it clearly caused a lot of trouble at the time.
The very latest DTC should make this process much more hit than miss, but still you'd need a drive with a very, very stable index signal to write that disk correctly.
What happens is that the data starts *exactly* at the index signal, and if the written track is a few microseconds shorter or the same as the original it is readable, but if it goes over size, even just by a few bitcells, the marks (sync) will be overwritten...
The latest DTC has a special functionality that takes care of this situation as much as is possible, but the bottleneck here is how consistent the index signal is on your drive - you'd have zero chance of writing this on the ALPS drive I used before.
Writing is correct on my Samsung drive now (the same as we had at the webshop), but YMMV...
I guess I am the only one here who can't actually try any of the games written, just see if they are correctly written or not - due to almost complete lack of retro gear where I live now.

Can't think of any other game that used such a stupid thing and it's no wonder they changed it for the running replacement

As usual, Mr Vince can get you the latest beta, if you don't have it yet.
I also have another idea, but that might have unwanted side effects...

Another thing that comes to mind with this first production run of GnG: It requires slow fast (ranger mem). So on my pimped CDTV in A500 mode (JP15 - ROMs disabled) it boots fine, fades the screen to black and gurus. The memory detection just tries to access ranger mem and if it's not there... boom.

So... does it actually do anything more than booting and fading, kipper2k?

Same symptoms, Fades to black and guru, other times, i thought i heard someone laffin at me

As for that, you need a very specific config to make the first release of GnG running - provided you have a good disk written.

KS1.3, 512 chip, 512 slow located at 0xc00000, it is also seems to be locked to PAL.
When it keeps on rebooting it means the config is wrong; you can try this in WinUAE.

Sooo... from looking at the image read back this is also a "good" one.

I was tempted to get my old A500 back from the basement but then... remembered I had modified the mobo to access the trapdoor mem as chipmem... so also a no-go for me.

But hey, we'll find someone with such a machine.

Great. I am looking forward to own it.

Don't worry... you will be helped!

is that the xenon 2 1-disk i submitted? I remember the first dump was bad and the second one being perfect which fiath said was nothing short of a miracle!

mr.vince · 09 July 2011, 17:00

Also dumped it once, so... could very well be it's yours or mine or a Frankenstein of both... in case bad tracks were exchanged between images.

together we can achieve anything! a work colleague gave me the xenon disk along with a box of others that had been in his loft for about 10 years

IFW · 09 July 2011, 19:16

Yes, it is a truly a miracle that disk is readable at all, as we said it's quite possibly the most dense disk ever on Amiga.

just checked my PMs and it was IFW that i was in contact with not Fiath regarding Xenon 2 !

Small world, huh?

Yeah, I knew that's what you'd say!!! All smug about making a great product, just to see if you can pry some money from my paypal account...
Well!! Just for that!!

er..

I ordered mine today.

Should give me time to find a 5 1/4" floppy at the local shop. (Can't believe I don't have one anymore, but my junk piles failed me on that one..)

Thanx!! (Darn you)

Excellent News :-)

I might have to buy a second KF :-)

Jope · 10 July 2011, 13:19

Well done guys! I think I need to buy one real soon now. :-)

Not for writing... Unless you intend to use it in a different place, you can use the very same board you already have to write.

kipper2k · 12 July 2011, 19:08

I have to say it is so nice being able to play a game that you know is the original and (shouldnt) crash. I like the cracked games if i want to cheat etc, but its really nice to know that there is a choice now

mr.vince · 19 July 2011, 13:31

I know some will see this as an insult, but it's not meant this way.

We just felt the ST deserved it as well. Enjoy!
