How do you guys to integrate code from third parties?
There's a guide for conversion?
Lot of thanks

; +0 (2) direccion actual (el canal esta libre si el byte alto = # 00)

module PT3PLAYER
;Vortex Tracker II v1.0 PT3 player for ZX Spectrum
;(c)2004,2007 S.V.Bulba <vorobey@mail.khstu.ru>
;http://bulba.untergrund.net (http://bulba.at.kz)
;Release number
Release EQU "7"
;Features
;--------
;-Can be compiled at any address (i.e. no need rounding ORG
; address).
;-Variables (VARS) can be located at any address (not only after
;code block).
;-INIT subroutine detects module version and rightly generates
; both note and volume tables outside of code block (in VARS).
;-Two portamento (spc. command 3xxx) algorithms (depending of
; module version).
;-New 1.XX and 2.XX special command behaviour (only for PT v3.7
; and higher).
;-Any Tempo value are accepted (including Tempo=1 and Tempo=2).
;-Fully compatible with Ay_Emul PT3 player codes.
;-See also notes at the end of this source code.
;Limitations
;-----------
;Can run in RAM only (self-modified code is used).
;Warning!!! PLAY subroutine can crash if no module are loaded
;into RAM or INIT subroutine was not called before.
;Call MUTE or INIT one more time to mute sound after stopping
