I follow the discord, I saw everyone very enthusiasm, but I must confess, I didn't understand everything, I'm sorry.

You've been following discord of the DS and KOS. What improvements are you talking about exactly?
About DS I write here. About my improvements for KOS not.
Sometimes I transfer some things born in the ISO loader to KOS with some additional improvements exactly for KOS.
For example I'm improved KOS sound streams with highly optimized for SH4 the PCM splitting algorithm that I wrote on assembler for ISO loader.
Dreamcast AICA SPU can't simply play stereo PCM, so separate channels are needed as mono to play them back separately with different panning.

BTW, this PCM splitting algorithm economy some CPU time for the SD soft SPI hard work, so this is more noticeable on SD with RAW CDDA.
Especially with the additional ~5% improvement for the SPI itself. It's very close to playable now. The SD users will appreciate this
Also I have some idea to improve PCM loading a bit more if the file is defragmented... Perhaps this will give something. Or not, I should check it.
Lots of ideas but not enough time in the day.
