Re: Where can I find a CRC32 68000 code?

Hi $EDB88320 is the so called "reversed" crc32, in the sense that it uses the same polynomial $04C11DB7, except you don't shift bits to the left, but to the right (which can be more efficient depending on the cpu little/big endianess) See for example : https://www.hackersdelight.org/hdcode...

Re: High density .STX / pastis support

Hi, I havent't checked the code, but maybe emutos tries to read in HD then in DD (if HD fails), whatever the value of the cookie is ? And in that case this would allow this STX floppy to work. In all cases, I will add support for ff860e lowest 2 bits, so this should make emulated TOS works similar t...

Re: High density .STX / pastis support

Hi I also had a look at the STX file, and it looks rather "normal", no specific protection. It's just that each track has 10 sectors and each sector is 1024 bytes instead of 512 bytes. I would need to have a look at the TOS 2.06 code to see how it checks that the drive is DD or HD (ie how ...

Hi
version 2.2.1 was released ; it fixes the 'UNPK' bug and the macOS display problems.
Top message of this section was udpated.

Re: High density .STX / pastis support

Not all mega STe were produced with an HD drive, first ones were DD and Hatari emulates a DD drive (at least, I never looked into TOS code to see how it checks for DD drive or HD drive, could be an addition for next Hatari version, but I don't think it's related to your STX floppy image)

Re: High density .STX / pastis support

Hatari already handles 1.44 MB HD disks or even 2.88 MB ED disks in the sense that it will accept floppy images with 18 or 36 sectors per track instead of 9 for example, so I think it's really specific to this STX image.

Re: High density .STX / pastis support

So, I'll wait for Ijor to inspect the STX image you posted, maybe it doesn't work under Hatari because the image itself is flawed after the HxC conversion.
If Ijor confirms that the image is OK (timings apart), then I will look into Hatari code to see what is missing.

Re: High density .STX / pastis support

Yes, you can post it and I will have a look (could take a few days, I'm rather busy at work at the moment)
By the way, why STX for this floppy image and not plain .ST ? Is this floppy protected ?

Re: High density .STX / pastis support

Never having any example of an HD STX image, this is not supported in Hatari. But 0xA0 doesn't mean HD disk for me, it means a 2 sided floppy with 80 tracks on each side, hence 160 tracks total. An HD track should be be twice "larger" than the usual ~6 KB of data per track, but this should...

Re: High density .STX / pastis support

Hi
I was not aware that STX files existed in high density ; since pasti requires a 68000 STF/E for accurate cycle timing when analyzing protected disk, I did not know that a ST could read HD disk in that case.
Or maybe those HD STX files were not produced with pasti but with another tool ?

Your fix is good!

I used unpk indeed for bcd -> text.

Thanks!

Very quick fix by the way.

Thanks, but too bad this bug was not seen before release. I think an Hatari version 2.2.1 will be needed, with some fixes for the macOS issues once the causes are found.

Hi Christer Solskogen who maintains his own version of the windows version of Hatari on antartica.no has added support for portaudio and said recently he will try to add support for portmidi too. So, you might want to check his builds in the next days, maybe he will have time to do the change. Nicolas

Re: R0X ZER0

The solution is in fact quite simple : emutos starts in 60 Hz, but the credits screen requires 50 Hz to work correctly (ie 512 cycles per line) Most european TOS are starting in 50 Hz, so the credits screen is OK, but you would get the same error with a US TOS. Thanks, I hadn't noticed that 512k ve...
