ChanServ changed the topic of ##yamahasynths to: Channel dedicated to questions and discussion of Yamaha FM Synthesizer internals and corresponding REing. Discussion of synthesis methods similar to the Yamaha line of chips, Sound Blasters + clones, PCM chips like RF5C68, and CD theory of operation are also on-topic.

<ej5> oh yeah! hey everyone, yesterday i was able to dump the ct1351v202 ROM!
<cr1901_modern> Surprised there was even any ASCII strings in there lol
<Foone_> looking forward to seeing it diffed against the one we've been using. I'd be unsurprised to find out it's functionally identical
<cr1901_modern> this is the first I've seen that probing works
<cr1901_modern> I thought it required a FIB to do

<cr1901_modern> ej5: Are you willing to share the dump right now or is it gonna be private for now?
<cr1901_modern> Actually, I probably shouldn't see it
<cr1901_modern> so if someone can give me docs I can rewrite a clean room version
<cr1901_modern> (docs based on what was seen in the actual code*)
<ej5> correct.
<ej5> i'll document it at some point
<cr1901_modern> There needs to be a way to prove I've never seen the actual binary before (beyond the few bytes shown on Twitter as Fair Use)
<cr1901_modern> if I go down the rewrite route
<cr1901_modern> Also need an 8051 assembler that doesn't suck (LOL)
<cr1901_modern> Hopefully that situation has changed in the past... 7 years since I last touched 8051?
<ej5> there are some open source assemblers
<cr1901_modern> ahh, the pickings 7 years ago weren't... great
<cr1901_modern> ASEM-51 was the one I used
<cr1901_modern> closed source Windoze only
<cr1901_modern> but free
<cr1901_modern> It appears to no longer be Windoze only
