Has anyone done a sb16dumper run on a 4.11 card yet?

4.11 just needs to be checked if it works properly.
I have a card with it but it uses a non-standard connector db62 vs db15.

So far, we have ALL 4.xx fw (4.04, 4.05, 4.11, 4.12, 4.13, 4.16).
4.16 and 4.12 was not previously known as dumped. Great job done !
Мy sincere gratitude to everyone involved in the project.
Special thanks to main testers: @S95Sedan and @mattw !

Nice job on the coding.

I changed my post a bit aswell and added d52 mappings i have so far, as only 4.05 was partially done.
Used https://github.com/schlae/sb-firmware/tree/master as reference.

I have automated tool for 4.xx fw parsing (to make D52 .ctl file for D52 disassembler). But it needs some fixing and polishing.

Typo probably, should be fixed now.

Did you do power off/on before dump ?

Though i dont have aweutil running currently so possibly thats affecting it?

On the other hand have you checked how 4.16 is fixed against hanging notes bugs? Looks the most proper way to improve the firmware is to make fixes on 4.13.

Yes, 4.16 is obviously fixed hanging notes bug, i see it in code.
Nevertheless, same sloppy bug in interrupt handlers - they forget to push/pop psw

When comparing 4.16 looks alot like 4.13 with stuff removed in certain sections.
Theres also a db reference in 4.13 (X0a60) that isnt present in 4.16 (X0260) and calls something completely different.

Edit; Dumping works with aweutil on aswell on the ct3900 for 4.12.

what address of this point of interest in v4.13 ? It cannot be 0x0A60 - it is middle of samplerate convertion table

The part thats starts at 08b7 for 4.13, and 07e6 for 4.16.

Code looks the same. Cannot see a difference.

Yeah the code is the same but the routine doesnt jump to the table in 4.16. (hence the X0a60 vs X0260)
Dont know if this is intentional or another error on their part.

This is not a code !
This is data, samplerate conversion table ))

Same result, I'm just going to assume there is something about this particular card/computer that is problematic and move on. Seems 4.12 as already been verified by at least two people.
