root/cebix/SIDPlayer/src/sys.h
Revision: 1.5
Committed: 2003-10-21T16:56:19Z (21 years ago) by cebix
Content type: text/plain
Branch: MAIN
Changes since 1.4: +1 -1 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!)
