From acb0917556fc33681c1df5a530cf754193e67705 Mon Sep 17 00:00:00 2001 From: Andree Buschmann Date: Sun, 7 Aug 2011 20:01:04 +0000 Subject: Submit initial patch from FS#12176. Adds support for several new game music formats (AY, GBS, HES, KSS, SGC, VGM and VGZ) and replaces the current NSF and NSFE with a new implementation based on a port of the Game Music Emu library 'GME'. This first submit does not cover the full functionality provided by the author's original patch: Coleco-SGV is not supported, some GME-specific m3u-support has been removed and IRAM is not used yet. Further changes are very likely to follow this submit. Thanks to Mauricio Garrido. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30264 a1c6a512-1295-4272-9138-f99709370657 --- apps/codecs/libgme/sgc_cpu.c | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 apps/codecs/libgme/sgc_cpu.c (limited to 'apps/codecs/libgme/sgc_cpu.c') diff --git a/apps/codecs/libgme/sgc_cpu.c b/apps/codecs/libgme/sgc_cpu.c new file mode 100644 index 0000000000..3bd2d15df9 --- /dev/null +++ b/apps/codecs/libgme/sgc_cpu.c @@ -0,0 +1,36 @@ +// Game_Music_Emu 0.6-pre. http://www.slack.net/~ant/ + +#include "sgc_emu.h" + +#include "blargg_endian.h" +//#include "z80_cpu_log.h" + +/* Copyright (C) 2009 Shay Green.
