Hello!
I've readed the posts about PC Speaker digital samples emulation and there was information that it's not possible. But... that was in 2004. May be now something is changed? 😉

P.S: When I started the old DOS programs using Samplers (in Mushroom format) in some cases I've got a normal sound - for example in Never demo everything is OK, but CPSU demo as well as intro of Toppler game is not working.

P.S.S: May be this problem can be solved by configuration of real model of PC (for exapmle IBM PC XT 5 MHz, IBM PC AT 12MHz e t.c.) with exact timing?
