Re: Mega STe wanted

"HDS051H COMPUTER MEGA STE 4MEG/50HD RECON 849.00
HDS102 COMPUTER FALCON 4 MEG/80HD RECON 850.00 CALL?"

However, last updated in 2015 ...

$850 for a Falcon is a good price. $850 for a Mega STE is indeed a bit over the top. US is different, sure, but €200-300 is more the norm.

So it turns out my originals are actually version 1.2! I was obviously confusing them with the cracked version of 1.4 I have. I will image them up anyway when I get some free time.

Re: Req : "Audio Sculpture" (STX,...) even not running...

Alright. So since Hatari doesn't emulate the 6301 and a program there is indeed used for decryption of the main application code I needed to do a bit more work. But now I have the 1.5 image working in Hatari as well. as15_hatari.png PS: I'm sort of sure there's an emulation issue with timing when in...

Re: Req : "Audio Sculpture" (STX,...) even not running...

I don't see the same thing. The TRAP 1 should work, a vector is set at address $84 to $6047a, no need to NOP it. What value do you see at $84 ? Well, that trap vector was set much earlier during trace decoding IIRC. It will set trace active, move $e00030 to a0 and jmp(a0). From the below it sounds ...

Re: Req : "Audio Sculpture" (STX,...) even not running...

Do you mean you found the cause for the crash and what is missing in emulation ? Or that you changed some values by hand to avoid the crashing part (maybe similar to what I did to read track 3 too) ? The second interrupt during the STOP $555 drops to user mode after the RTE, that's why the stack po...

Re: Req : "Audio Sculpture" (STX,...) even not running...

Alright, I have a quite clean way of passing track 2 now. As Ijor suggested the problem is surely in the emulation (of STOP edge cases). With that done I'm now able to read track 3 followed by 3x-37 where I haven't had time yet to see what causes the next fail. Could still be verification of data fr...

Re: Req : "Audio Sculpture" (STX,...) even not running...

Hi I also started doing a more "step by step" disasm to see where the protection crashes (is it due to a cpu emulation bug, or the content of read track/sector not being correct, or even a combination of these 2 problems ?). But in my case, I don't see the crash at 78000, I get a problem ...

(Separate post due to post size restrictions) Track 2 sector read decoded and disassembled. LAB_0005 is the entry point at $780d2. Note that it will decode its own running code as well so tracing it will get you further than you do by just looking at this disassembly. ; IRA V2.08 (Oct 25 2017) (c)19...

Re: Req : "Audio Sculpture" (STX,...) even not running...

edit: See later comments. There is code that crashes on track 2 but it's seemingly not a problem with what's located directly at $78000. No displacement needed. Something's strange with track 2 as well. First it's read with read track and loads the 0xDEADFACE magic found there into register D6. That...

Thanks for testing! Too bad about not being a "v1.5" though. AFAIK the only cracks available for AS are v1.0 in color and mono, and v1.4 in color (and that crack isn't perfect, has issues with disk access/refresh). A v1.3 in mono would be a nice release for a still active cracking group, I...

So TOKI-LOADER was used instead for the protection of Audiosculpture published by Expose Software. Alright, I'll check with Redhead.

I still don't understand what TOKI-LOADER has to do with Audio Sculpture, even an internal version sent to beta testers. Maybe compare the image and protection with Toki?

Re: STFM to DVI/HDMI project

On the GST-MCU revisions of the STe the shifter is inside a surface mount QFP (impossible to add an adaptor) Earlier STe revisions have the Shifter as a PLCC chip some are in a socket others surface mount. You could make a board for these motherboards. Well all STEs have a GST-MCU (MMU+Glue) - but ...

Re: STFM to DVI/HDMI project

Of course the Shifter is a separate chip also on STE. On some revisions of the GST-MCU the Blitter has been included in that chip, but the Shifter is still separate.
