FAO Fiath. The impossible dumps
I have had another go at dumping some disks on my Amiga (I must like punishing myself or something
![]() I picked a random game out of the attic, which turned out to be Toki, and dumped it 4 times using different configurations... 1. DF1:, Mode 0, caches off, Blizzard installed. 2. DF0:, Mode 0, caches off, Blizzard installed. 3. DF1:, Mode 1, caches on, Blizzard installed. 4. DF1:, Mode 0, caches off, Blizzard installed. Alternative SIMM. I was going to attempt to dump it with my blizzard removed, but I realised that I would have to get PC2Amiga working since my memory expansion will have to go with it. Maybe I will get it sorted one day... Anyway, after dumping the disks I transfered them to my PC and compared the dumps using Beyond Compare (a text/binary file comparason application). Supprisingly, they are all significantly different. Even dumps 1 and 4 which I thought should be identical show large differences and very different file sizes. I am currently uploading them to the FTP in the CraigT folder. Its going to take another 20 minutes or so to upload them (damn 56k ![]() |

RAW dumps can't be ever identical. It is impossible to start read exactly at the same position.
Don't worry, they are most likely just fine ![]() |

Exactly x 2.
When I have some more time (hopefully tonight, but you never know) I'll take a look. And maybe even catch up with some of my mail (Burseg) ![]() |

Mental note - Read the FAQ

Dump 2 worked fine!
![]() So I guess maybe it is the drive which was the problem... Wierd. Anyway, feel free to continue now, but remember to use that setup ![]() |

Okay great
![]() Well, I think it is worth uploading another disk under that config to check - just before you do a dumping blitz and we find something went wrong. I'm sure it'll be fine though. |

I'm uploading a dump of Sensible Soccer at the moment.
I dumped it thinking that you didn't have a dump of V1.1. But after looking at the CAPS database again it looks like I missed it ![]() |

Never mind, it was good to confirm that you have a stable dumping setup now - go ahead, dump the other games
![]() btw: the second disk is heavily modified, just in case you are interested. |

Just compared the first disk with the others we have and unfortunately your disk is a completely different version of Sensi, although it looks like the other v1.1 ones... too bad the second disk is modified.

Bit of a shame, really. I picked the game up a couple of weekends ago at a car boot sale for the bargain price of 50p
![]() ![]() [edit] Forgot to mention. This is the version of sensi that I have. Last edited by Craigt; 20 June 2004 at 22:18. |

The Sensible Soccer MFM disk format cannot be duplicated by normal means
