Talking from total ignorance, in yabause with satiator suport there is a not full implemented command.
satiator/satiator-yabause, line 118.
This command really loads menu.bin or menu.bin is only a file for test purposes???
There is some variables referencing "bios".
Thanks, I dont have a windows computer only a virtual machine with windows xp, and IDA neither, but im interested in give a look.
Do you found something interesting in CDB? What I want to find at this moment is an easy way for dump the rom, maybe if the rom is more accesible, more people will...
If Im in correct JHDL tried to dump the rom in programing mode.
What funtionality do you refer???
Not at all, sorry for no posting more progress.
The only Ive discovery at the moment is a kind of prompt on test pins.
Its a normal serial conection at 9600bps, you can write with an serial...
If I remember correctly, in the yabause source tree there is 3 files, called SH1-pseudo, mpeg.c and ygr.c (or something similar), from this files you can get almost all registers used from SH1.
SH1-pseudo looks extracted from coments of the dissasembled ROM code, probably done for JHDL, but in...
Sure, IIRC is related with two offset located in IP, one says were is the SH1 code, the other say the legth. I can try to find related code in rom.
PS: Ive clean my HD and installed ghidra, the c decompiler is interesting, some problems with arguments and return variables in funtions, the code...
Probably I never will put my hands on a satiator, so at the moment replicate what JHDL did six years ago is the only thing that I can do for get the CDB ROM.
The code discoveries done by JHDL has no been relased, so study the rom by myself is the only thing that i cand do for understand how CDB...
