2014-10-07opl: Use uint64_t for microsecond times.Simon Howard
Previous revamping of the OPL library changed delay times from ms to us, and switched to 64-bit times for storage for them. However this type change was botched and some functions were still using 32-bit arguments. Change to 64-bit types. Thanks Quasar for reporting this. This fixes #438.
2014-05-11opl: Change library to use us instead of ms.Simon Howard
Multi-track MIDI files are played back using separate callback chains for each track, and this introduces the possibility of one track becoming out of sync with the others. This was noticeable in WADs that use multi-track MIDIs, such as Alien Vendetta. Increase the timing resolution to microsecond precision to fix this.
2014-05-10opl: Add API to adjust tempo.Simon Howard
When the tempo is changed, the times on all active timers must be adjusted to match the new timing values. Add an API to do this and invoke it when a tempo change meta event is read.
2014-05-05Clean up file headers.Simon Howard
This change rewrites and simplifies the copyright headers at the top of all source files: * Remove "Emacs style mode select" line; this line was included in the headers for the originally released source files and appears to be to set the file type for old versions of Emacs. I'm not sure entirely why it was required but I don't think it is any more. * Remove "You should have received a copy of..." text from copyright header. This refers to the old 59 Temple Place address where the FSF headquarters used to be located and is no longer correct. Rather than change to the new address, just remove the paragraph as it is superfluous anyway. This fixes #311. * Remove ---- separator lines so that the file headers are barer and more simplified.
2013-08-11Remove Windows CE support.Simon Howard
What support exists is for obsolete devices I no longer possess; I've never been contacted about the port and it's been several years since I even bothered to build a new version. All the extra overrides are clutter that can just be removed. Subversion-branch: /branches/v2-branch Subversion-revision: 2615
