From: notaz Date: Tue, 21 Nov 2023 22:02:50 +0000 (+0200) Subject: apply cdrom volume in spu X-Git-Tag: r24~45 X-Git-Url: https://notaz.gp2x.de/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=38b8a211aad8d2c485ccf0c0cbb58d965aac3483;p=pcsx_rearmed.git apply cdrom volume in spu The previous sector delay thing breaks rhythm games. Also much easier to deal with timing in SPU code. --- diff --git a/frontend/plugin.c b/frontend/plugin.c index 88d756eb..c3c104af 100644 --- a/frontend/plugin.c +++ b/frontend/plugin.c @@ -46,20 +46,7 @@ static long CALLBACK CDRgetTE(unsigned char _, unsigned char *__, unsigned char static void CALLBACK GPUdisplayText(char *_) { return; } /* SPU */ -extern long CALLBACK SPUopen(void); -extern long CALLBACK SPUinit(void); -extern long CALLBACK SPUshutdown(void); -extern long CALLBACK SPUclose(void); -extern void CALLBACK SPUwriteRegister(unsigned long, unsigned short, unsigned int); -extern unsigned short CALLBACK SPUreadRegister(unsigned long, unsigned int); -extern void CALLBACK SPUwriteDMAMem(unsigned short *, int, unsigned int); -extern void CALLBACK SPUreadDMAMem(unsigned short *, int, unsigned int); -extern void CALLBACK SPUplayADPCMchannel(void *, unsigned int, int); -extern void CALLBACK SPUregisterCallback(void (*cb)(int)); -extern void CALLBACK SPUregisterScheduleCb(void (*cb)(unsigned int)); -extern long CALLBACK SPUfreeze(unsigned int, void *, unsigned int); -extern void CALLBACK SPUasync(unsigned int, unsigned int); -extern int CALLBACK SPUplayCDDAchannel(short *, int, unsigned int, int); +#include "../plugins/dfsound/spu.h" /* PAD */ static long CALLBACK PADinit(long _) { return 0; } @@ -191,6 +178,7 @@ static const struct { DIRECT_SPU(SPUregisterScheduleCb), DIRECT_SPU(SPUasync), DIRECT_SPU(SPUplayCDDAchannel), + DIRECT_SPU(SPUsetCDvol), /* PAD */ DIRECT_PAD(PADinit), DIRECT_PAD(PADshutdown), diff --git a/libpcsxcore/cdrom.c b/libpcsxcore/cdrom.c index 013be599..fac5fd39 100644 --- a/libpcsxcore/cdrom.c +++ b/libpcsxcore/cdrom.c @@ -633,7 +633,6 @@ static u32 cdrAlignTimingHack(u32 cycles) static void cdrUpdateTransferBuf(const u8 *buf); static void cdrReadInterrupt(void); static void cdrPrepCdda(s16 *buf, int samples); -static void cdrAttenuate(s16 *buf, int samples, int stereo); static void msfiAdd(u8 *msfi, u32 count) { @@ -693,9 +692,8 @@ void cdrPlayReadInterrupt(void) if (!cdr.IrqStat && (cdr.Mode & (MODE_AUTOPAUSE|MODE_REPORT))) cdrPlayInterrupt_Autopause(); - if (!cdr.Muted && cdr.Play && !Config.Cdda) { + if (cdr.Play && !Config.Cdda) { cdrPrepCdda(read_buf, CD_FRAMESIZE_RAW / 4); - cdrAttenuate(read_buf, CD_FRAMESIZE_RAW / 4, 1); SPU_playCDDAchannel(read_buf, CD_FRAMESIZE_RAW, psxRegs.cycle, 0); } @@ -933,6 +931,11 @@ void cdrInterrupt(void) { break; case CdlPause: + if (cdr.AdpcmActive) { + cdr.AdpcmActive = 0; + cdr.Xa.nsamples = 0; + SPU_playADPCMchannel(&cdr.Xa, psxRegs.cycle, 1); // flush adpcm + } StopCdda(); StopReading(); @@ -978,9 +981,11 @@ void cdrInterrupt(void) { StopReading(); SetPlaySeekRead(cdr.StatP, 0); cdr.LocL[0] = LOCL_INVALID; - cdr.Muted = FALSE; cdr.Mode = MODE_SIZE_2340; /* This fixes This is Football 2, Pooh's Party lockups */ cdr.DriveState = DRIVESTATE_PAUSED; + cdr.Muted = FALSE; + SPU_setCDvol(cdr.AttenuatorLeftToLeft, cdr.AttenuatorLeftToRight, + cdr.AttenuatorRightToLeft, cdr.AttenuatorRightToRight, psxRegs.cycle); second_resp_time = not_ready ?
