Actually ... I did not even know about this: https://en.wikipedia.org/wiki/Hi-MD had a capacity for 94 minutes PCM. Brought to you by the creators of Betamax ...But I cannot imagine industry support - rather, one would have to expect major costs fighting the RIAA back then when they tried to restrict audio-on-CD-R to very special hardware and media.
Timing played a role as well. As the Nintendo GameCube could not play DVDs either. Being the first out in a console generation and yet not utilizing the DVD format was stupid of SEGA. It allowed Sony to gain an edge.
I think if SEGA skipped the 32X, supported the Saturn better it would've turned out better for them.
The PS3 wasn't exactly 1st place in it's generation despite being the only console to play Blurays.
Also consumer confusion can affect a business. Nintendo was very successful with the Wii but when they went to release a new console they called it the "Wii U".
And finally the overall quality and value of a product and who it's marketed towards can determine it's success and adoption. With a format you want as many people to adopt it as possible. With a game console the quality of the software library and the consumer base that adopts it can affect you, not just in the present tense but also later on.
[...]normally inaudible integer overflow [...]Huh? The only way for "integer overflow" to be inaudible is to not overflow. Any tiny amount of overflow will be clearly audible. ( ok.. maybe with white noise it could be hidden under the SNR, but otherwise... )

Thanx @Phanton_13 I find your post really exciting! I will give a good read at your links!
I sometimes find it bad since sometimes, I want to ABX Opus with another codec, but just because Opus outputs 48kHz audio, I have to go for extra measures just to resample the output of the other codec to 48kHz also.
You shouldn't resample other audio to 48k, you should resample the opus output to match the input. I am not certain, but I believe opusdec can do this automatically.
Is this in reference to my opus clipping remark? If so, I was considering clipping because the artifact was described as sounding like it and the material was chiptunes, which can cause normally inaudible integer overflow or clipping bugs to suddenly become very noticeable. A full scale square wave will often make it very clear if your processing steps need more headroom.
For software that handles things correctly, lossy induced clipping should not be audible.

halb27, thank you for the sample harp40_1 and tests.
Let's see if devs can do something with it.
a) do I have to worry about the clipping? I guess I have to, but I'd be very pleased if somebody could convince me of the contrary. Maybe there are studies out there about it, but I've never heard of it.I'm not worried... When I make an MP3 I know I'm making a lossy file... But, I expect it to sound good (if the original sounds good ) ...and it always does.
Some people reduce the volume before making a lossy copy, but I don't bother.
If I want perfection, I'll go lossless.
