Revision:	1.4
Committed:	2003-10-21T16:56:19Z (21 years ago) by cebix
Content type:	text/plain
Branch:	MAIN
Changes since 1.3:	+3 -3 lines
Log Message:	- play_adr is updated from the IRQ vector every time before the replay routine is called if it was 0 in the PSID header (this makes some tunes play correctly now) - f(void) -> f() (this is C++, dammit!)
