From 6b947e0353e1257461ffe17a2102d32b8cf1db14 Mon Sep 17 00:00:00 2001 From: DJRobX Date: Thu, 8 Nov 2007 11:42:08 +0000 Subject: [PATCH] GB use blargg's audio core correctly Noise channel seems to be buggy in GBA mode (probably using uninitialized data somewhere). Suddenly became very LOUD. Changed volume setting for now. OpenGL is looking for glext which is not part of a standard windows build. Probably should incldue it in dependencies if we are going to use it --- src/GBA.cpp | 22 +- src/GBA.h | 2 +- src/GBAinline.h | 989 ++++++++++++++++++------------------- src/Gb_Apu/Blip_Buffer.cpp | 2 +- src/Gb_Apu/Gb_Apu.cpp | 2 +- src/Gb_Apu/Gb_Oscs.cpp | 34 +- src/Gb_Apu/Gb_Oscs.h | 7 + src/Link.cpp | 2 +- src/Sound.cpp | 5 +- src/gb/GB.cpp | 11 +- src/gb/gbSound.cpp | 598 ++++------------------ src/gb/gbSound.h | 4 + src/win32/OpenGL.cpp | 3 + 13 files changed, 672 insertions(+), 1009 deletions(-) diff --git a/src/GBA.cpp b/src/GBA.cpp index 7ccdb4b5..8207366f 100644 --- a/src/GBA.cpp +++ b/src/GBA.cpp @@ -90,6 +90,7 @@ u32 busPrefetchCount = 0; int cpuDmaTicksToUpdate = 0; int cpuDmaCount = 0; bool cpuDmaHack = false; +bool cpuDmaHack2 = false; u32 cpuDmaLast = 0; int dummyAddress = 0; @@ -2313,11 +2314,15 @@ void doDMA(u32 &s, u32 &d, u32 si, u32 di, u32 c, int transfer32) } -void CPUCheckDMA(int reason, int dmamask) +bool CPUCheckDMA(int reason, int dmamask) { + bool res = false; + cpuDmaHack = 0; + // DMA 0 if((DM0CNT_H & 0x8000) && (dmamask & 1)) { if(((DM0CNT_H >> 12) & 3) == reason) { + res = true; u32 sourceIncrement = 4; u32 destIncrement = 4; switch((DM0CNT_H >> 7) & 3) { @@ -2375,6 +2380,8 @@ void CPUCheckDMA(int reason, int dmamask) // DMA 1 if((DM1CNT_H & 0x8000) && (dmamask & 2)) { if(((DM1CNT_H >> 12) & 3) == reason) { + res = true; + u32 sourceIncrement = 4; u32 destIncrement = 4; switch((DM1CNT_H >> 7) & 3) { @@ -2444,6 +2451,7 @@ void CPUCheckDMA(int reason, int dmamask) // DMA 2 if((DM2CNT_H & 0x8000) && (dmamask & 4)) { if(((DM2CNT_H >> 12) & 3) == reason) { + res = true; u32 sourceIncrement = 4; u32 destIncrement = 4; switch((DM2CNT_H >> 7) & 3) { @@ -2514,6 +2522,7 @@ void CPUCheckDMA(int reason, int dmamask) // DMA 3 if((DM3CNT_H & 0x8000) && (dmamask & 8)) { if(((DM3CNT_H >> 12) & 3) == reason) { + res = true; u32 sourceIncrement = 4; u32 destIncrement = 4; switch((DM3CNT_H >> 7) & 3) { @@ -2565,6 +2574,8 @@ void CPUCheckDMA(int reason, int dmamask) } } } + cpuDmaHack = false; + return res; } void CPUUpdateRegister(u32 address, u16 value) @@ -3846,6 +3857,8 @@ void CPULoop(int ticks) int timerOverflow = 0; // variable used by the CPU core cpuTotalTicks = 0; + if(cpuDmaHack2) + cpuNextEvent = 1; cpuBreakLoop = false; cpuNextEvent = CPUUpdateTicks(); if(cpuNextEvent > ticks) @@ -4044,7 +4057,7 @@ void CPULoop(int ticks) IF |= 1; UPDATE_REG(0x202, IF); } - CPUCheckDMA(1, 0x0f); + cpuDmaHack2 = CPUCheckDMA(1, 0x0f); if(frameCount >= framesToSkip) { systemDrawScreen(); frameCount = 0; @@ -4164,7 +4177,7 @@ void CPULoop(int ticks) DISPSTAT |= 2; UPDATE_REG(0x04, DISPSTAT); lcdTicks += 224; - CPUCheckDMA(2, 0x0f); + cpuDmaHack2 = CPUCheckDMA(2, 0x0f); if(DISPSTAT & 16) { IF |= 2; UPDATE_REG(0x202, IF); @@ -4328,6 +4341,9 @@ void CPULoop(int ticks) goto updateLoop; } +// if(cpuDmaHack2) + // cpuNextEvent = 1; + if(IF && (IME & 1) && armIrqEnable) { int res = IF & IE; if(stopState) diff --git a/src/GBA.h b/src/GBA.h index a79603b2..3595500e 100644 --- a/src/GBA.h +++ b/src/GBA.h @@ -116,7 +116,7 @@ extern void CPUWriteByte(u32, u8); extern void CPUInit(const char *,bool); extern void CPUReset(); extern void CPULoop(int); -extern void CPUCheckDMA(int,int); +extern bool CPUCheckDMA(int,int); extern bool CPUIsGBAImage(const char *); extern bool CPUIsZipFile(const char *); #ifdef PROFILING diff --git a/src/GBAinline.h b/src/GBAinline.h index e1ea5f13..b268c6e5 100644 --- a/src/GBAinline.h +++ b/src/GBAinline.h @@ -1,499 +1,498 @@ -// -*- C++ -*- -// VisualBoyAdvance - Nintendo Gameboy/GameboyAdvance (TM) emulator. -// Copyright (C) 1999-2003 Forgotten -// Copyright (C) 2005 Forgotten and the VBA development team - -// This program is free software; you can redistribute it and/or modify -// it under the terms of the GNU General Public License as published by -// the Free Software Foundation; either version 2, or(at your option) -// any later version. -// -// This program is distributed in the hope that it will be useful, -// but WITHOUT ANY WARRANTY; without even the implied warranty of -// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
