I bet that it hasn't enough "horse-power" to do that "on the fly".
Maybe if it had a DMA since the beginning we could develop a DSP to
handle such datastreams ... But seems useless to me do such things
on a DMAless machine. =(
Hey Pazos ! What you think of that ? Any sugestion ? =)

That option makes EVA use a external PCM device cartridge instead
of the internal Turbo-R PCM. (I bet that it's the old PCM-MAN
cartridge.)

Yes , you disable the mic by plugging anything to the AUX PCM input
plug.
About being drunk I dunno , because I don't have supernatural powers to
guess your alchoolic levels ! ;)

I bet that the problem is DOS2.
If someone develops a "direct access" MSXCDEX I think that will be
possible.

Not that much ... Belive me ... My PC is SCSI ... =)
