This version of Dragon Adventure uses a few PD 
sound effects.

It uses Rick Hudson's freeware PlayIt module to do 
this (included), which is Iyonix 32-bit compatible. 
Dragon Adventure itself is written in standard BASIC 
and should work on the Iyonix without problems.

Playit does not work with RiscOS 3.1, so
installing the patch for older machines will also 
install Rick's older PlaySample module alongside 
the PlayIt module, and this will be used instead. 

The patched version should work with any older 
Archimedes/monitor syatem that can support 
256 colour VGA graphics (Mode 27). This includes
the A5000 and the VirtualA5000 emulator on the PC,
and possibly some CC ColourCard systems.

Playsample is freeware and released under the GNU 
public licence agreement.
