Re: R: [hatari-devel] HATARI: no emulation of a Real SF354 Single Sided drive

[Troed Sångberg <troed@xxxxxxxxxxx>]

Does the original work on a real SF314? There's no logic in an ST floppy drive, an SF354 is the same as an SF314 that only reads on side. 

Also, I'm wary about the intermediate conversion to STX. 

But yes, I assume the game manages to find content from side 2 it doesn't consider valid. I'm not sure the correct solution is to force the emulated drive to be single sided without knowing that the original game fails on an SF314.

Yes, the dump is made in single sided mode naturally 😊

But on the emulator it doesn’t work, even on a SF314 original Floppy Machine (Double Sided) because the Original protection Check If Find an SF354 unit 😊

 

So on HATARI there will be an emulation separately for the SF 354 drive and gehe SF314 (similar to the one inside the 1040).

 

That’s the problem 😊

Hi,

 

Isn't this simply because the actual original is a single sided disk, and so your dump should be single sided as well?

 

From memory:

 

gw read --tracks="c=0-79:h=0" ss.scp

 

regards,

Troed

Hi guys.

I've a Greaseweazle and I'm dumping a lot ST's originals.

I've discovered some, like first press in Double Jewel of Metro Cross (UK version) that the SCP converted in STX it reset on HATARI as I read it with an SF 314 drive that is Double Sided as you know.

If I clone the dump on another diskette and I load on my 520ST with the SF354 It works perfectly.

So I suppose that the actual floppy emulation (single sided) is based on the SF314 drive or on the interna 1040 STF.

If this bug can be corrected It will be appreciated.

I can attach the SCP image or send a link on my Dropbox for download it.

Best regards.
