That might be tricky, as I don't know anyone with an Amiga. However, I was planning to use ADFFS to image the disks, surely that will do?

So far I've found time to read the manual and try out the discs to see if they still work. The good part is that the discs do work, as far as I've been able to test. :D The less good part relates to playing the game itself, which gave me a bit of a flashback to 1992 and reminded me why I never playe...

Good news ... I have found that I have both the discs and the manual!

I will see if I can image the discs and will scan the manual. Might take me a while though.

The Amazon listing says this: Connectors: 1 x VGA 15-pin male on one end - 1 x S-Video mini-DIN 4-pin connector and 3 x RCA composite connector on other end. • This VGA to S-Video + 3 RCA Adapter connections your PC / Laptop to LCD projector, HDTV, or any other display devices.

Hang on a minute... as of right now, it's changed to a green padlock on almost all pages! Have you changed something? This doesn't apply to every single page though. The thread Re:BeebSCSI mini shows a white circle with a !, meaning 'connection not fully secure'. This applies to pages 3-5 of that th...

'your connection to this site is not secure'

Wiping the cache has helped. I no longer get all the warnings, just a red triangle symbol with a ! in it.

I'm getting these warnings as well, on my Android tablet. I've just installed the latest version of Chrome and if anything, the warnings have become even more dire!

In Windows, and on my iPhone, everything seems OK though.

I think they are:
LS00 - not gates
LS33 - nor gates
LS682 - 8 bit comparator

I wonder how the comparator is being used in this context?

Not experimented with *free yet, but adding padding to my unrecognised images has fixed them.

I did also make a file containing 640*1024 zeros, with a .ADL extension, with a view to formatting it, but this was rejected with err 31 again.
Maybe it needs .ADF?

Non-padded DFS images do mount and catalogue correctly though. Does this mean that they have very little free space on - ie they never grow to the right size?

Would make sense if so, because all the other DFS and ADFS images that I can find on the Gotek are fully padded.

No they are only 2k in size. They are just whatever Elkulator and ADFS explorer put out. But I’m sure you are onto something!

This doesn’t seem to apply to DFS?

I've been loading more and more disk images onto my Gotek and realised it would be handy to put some blank ones on there as well. Blank DFS images seem to work fine, but I've encountered some problems with blank ADFS images. When I try to select them, Flashfloppy reports "ERR 31". I tried at first w...

While finding useful disc images to go onto my Gotek, I found the "Exile-fixed" image and couldn't remember what is was. Then I found this thread, and noticed that it's not clear whether password-free version of Exile can load savefiles correctly. Well, I've just checked, and it can't. So I've merge...

It's a good question, and one which Electron owners faced back in the 80s. The MRB was the winner back then because it was cheaper, easier to understand for the casual user, fitted inside the case, and offered a Turbo mode which gave some speed benefit without breaking compatibility too much. These ...

Cumana just put proprietary drives into cases. You need to figure out who actually made the drive, and then try Googling that.

The Sony TV also has another problem with BBC machines, which is unrelated to Frogger. It sometimes can't do the sub-pixel antialiasing in Mode 7, displaying a sort of checkerboard effect instead. This tends to go away if you blank the screen (eg by changing mode).

Good news - I've managed to solve this problem! :D And I think it does shine some light on the video timing issue actually. All I did was switch to a different TV (a Samsung Syncmaster 510MP). On this other TV everything works fine. So this means that the first TV (a Sony) wasn't entirely happy with...

Do they sit on the 2Mhz(?) data bus? Yes they do. I'm not very familiar with the 1MHz bus, so I'm sure others can do a better job of explaining, but the cartridge slots provide access to the processor's address and data buses, plus Phi0, IRQ and NMI lines etc. I think this makes the cartridge inter...

Good point, that makes sense! My Master does boot up into a shadow ram mode. Explains why it worked OK in Master mode on BeebEm. EDIT: I have reconfigured it to boot to a non-shadow mode, but the problem persists. Definitely works OK in BeebEm (in Master mode). I checked the value of HIMEM to be cer...

I don't know if this is in any way related to the video timing issues being discussed, but I tried out Frogger on my real Master today using the Gotek interface to load it. The results were odd: the screen display is perfect, and the game seems to play ok, but I am seeing no screen updates at all! i...

Good point about disabling the Plus1, I’ll try that.

I have just discovered a rather odd incompatibility betwen Codename Droid and the AP6 rom. With the rom inserted, the game runs, but black background tiles are filled up with mostly-white but also slightly randomised corruption. I'm talking about the ADFS disc version. I'm not suggesting that this i...

I struggle to imagine how it could be much better than it already is. However I do have a practical suggestion, which is whether it could be ported to the 6502 second processor. This would free up a lot of memory which could be used for more sound samples perhaps?

The FAT sorter did the trick, thanks. My wife always said I needed to sort my FAT, so she ought to be pleased as well. 8) Ray, I've been using your menu system and it's excellent. I've made a small improvement to the ADFS version though - it prompts to load from drive 1 or 2, but if you have a hardd...

Aha! Thanks, never heard of those before but it makes sense.

Got mine working - I really enjoyed putting it all together! In the end I have used an old BlackBerry USB charger. I don't know to what extent it is regulated, but it seems to work well with the Gotek. The only real problem I have encountered relates to how the folders on my USB stick appear on the ...

Get a Mac :) Expensive but that is what you are asking ‘Unix where you don’t need to use command line’. I had the same thought myself a little while ago. However when I wandered over to the Macs in the computer shop, I had to pick myself up off the floor when I saw the prices. :shock: Maybe a used ...

I've got a Win7 laptop which is basically fine, and I have resisted "upgrading" to Win10 for all the above reasons. However, it will inevitably break in the end, which means I will have to make a tough decision - buy a Windows 10 laptop or go for Linux. I have got Lubuntu 14 installed as a dual boot...

it has just occurred to me that the algorithm matches the plot of the novella: in the story, Triax adapts the natural cave system to his own evil plans, whereas the map generation system allows local manipulation of a "naturally" generated map.

It's genius.
