@all, thank you, even your comments are too technical for newbie like me to understand. my point is that 8-bit is less than 9-bit and yet 8-bit PCMs sound fine...

IMHO, such thing is outside the scope and most importantly the main goal of this project, which aims to achieve bit-perfect output of the digital circuit and doing so with...

great, but also make note what are the exact chip marking, because there are at least 2 controlrom versions for SC-155: "R15209361" or "R15209400".

so, your SC-155 is not using "R15199799" MCU?! because R15199799 is dumped, SHA1: 76f646bc03f66dbee7606f2181d4ea76f05ece7d

if that is the inside of your SC-155, as far as I can tell from that blurry picture it's R15199799.

IMHO, public or not it doesn't matter at the moment and thus better focus your time and energy on what is not dumped at all.

do any of you - the people commenting here, owns SCC-1A card, especially broken/faulty one that you are willing to sacrifice? I wanted to contribute for adding SCC-1A support to...
