Where can I download that software from? In my opinion, if it works in
DOSBOX, it can capture a DRO file on registers, so it can be played back on
C64 with OPL2 equipped SFX Sound Expander cartridge. However, it is
important to note, that it is really not the best way to do: as DRO file
simply contains regnumber-regvalue data pairs (and delay info) so if there
is rapid change on the registers, huge amount of memory is needed for even a
shorter audio. It would be great to know the exact method audio is generated
instead of just capturing registers. So then there can be a software like
that written for C64 which can say sentences, not only a fixed one.
