Re: Keyboard controller

Hi this ROM is a "F1" version as we already know it, not the rare "F0" one. You can see this at offset $DA with this instruction (I disassembled it some time ago to mimic its behaviour into Hatari) : F0DA : 86 F1 " " ldaa #$F1 ; A = $F1 F0DC : 97 13 " " staa X...

Re: Rastari

Interesting. Looks like a well-designed front-end for Hatari. But the project page is really shy about mentionning Hatari :( As it's a frontend and doesn't include Hatari sources, it's of course OK to do so. It would seem nicer to me if Rastari stated that the underlying emulator is Hatari (appart ...

looking at the screenshot, maybe you did not set cpu emulation to "cycle exact" mode ?

Re: STe/Falcon adjustable DMA sound volume

Hi so far, Hatari volume mixing is not configurable, it's hardcoded to these specific values, which are not too far from real STE, but not close enough. Some measures would need to be done on real STE machine to record YM wave and DMA sound playing square wave then comparing their respective amplitu...

Re: Hatari 2.2.1 has been released

Hi
the windows version from https://download.tuxfamily.org/hatari/ are compiled with IPF support ; I think the OSX version too, but I'm not sure.
It depends on the OS you use to know which libraries were used to compile Hatari, easiest solution remains to try to load an IPF file.

Re: High density .STX / pastis support

Hi I improved Hatari to better handle the DD/HD density for ST/MSA and STX floppy images. - In MegaSTE mode, upper byte of register FF9200 (DIP switches on motherboard) is now emulated too (it was only emulated for TT and Falcon). This register will return amongst other things the model of drive in ...

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 ...

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.

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 ?

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 ?

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.
