AUDIO - Nuked OPL3 Patch for DOSBox(+Windows build) (SDL1)
Posted on 2016-08-03, 14:11
This patch adds my Nuked OPL3 emulator to DOSBox SVN. Set oplemu to nuked in config file. Also set oplrate and mixer rate to 49716 for best sound quality.

No. It outputs in MP4.

I use Nvidia Shadowplay to record from DOSBox with Roland SC-55 music.

Can somebody record Stunts Intro music played on YMF289 (not on YMF7xx). YMF289 seems has some resampling artifacts.

According to OPL4 Application manual FM block uses Clock / 684 for internal rate, which gives 33.8688MHz/684=49515,78...Hz(6,98 cents lower than YMF262's rate) Also OPL4 output sample rate is 44100Hz, so it definetly uses resampler. I think YMF289 uses the same resampler(Same input clock, same …

Try out git build of Chocolate Doom. It uses my Nuked OPL3 enulator and has very accurate OPL driver(i_oplmusic.c) compared to DOS Doom.

opl2.png They sound the same and no different than none at all. LOL. You are using driver which emulates Windows 9x's SB16 OPL3 driver. Doom driver is separate from 'Windows 9x' driver. Download link in doomworld thread. Install both x64 and x86 versions and select 'Doom OPL3 Synth' for music …

Now it works, thanks. I had to install visual c++ 2015 redistributable 32 also (I already had 64). EDIT: The E1M1 midi and this driver doesn't actually sounds like doom E1M1 in dosbox (OPL), but it's very close. Impressive that the OPL can emulate GM sounds with nothing but wave-forms. I suppose I …

On x64 systems you should install both x86 and x64 versions. And did you install visual c++ 2015 redistributable?

I think you have to use value&0x3f here: https://bitbucket.org/superfury/x86emu/src/6031944d50d472d873c6f29389d386f9b6d3a66e/hardware/adlib.c?at=master&fileviewer=file-view-default#adlib.c-316 EDIT: You also have to multiply KSL value with 8 here: https://bitbucket.org/superfury/x86emu/src/ …

The 2*PI is actually the period of one sine wave. calcOPL2Signal(waveform,frequency,phase,freq0,time) gives the LogSin result that's requested. The LogSin table is looked up by normal sin() convertion (by executing modulo 2*PI and using that phase to determine the index into the OPL LogSin table. …

Is this correct? OPTINLINE float calcModulator(float modulator) { return modulator*PI2; //Calculate current modulation! } OPTINLINE float calcFeedback(byte channel, ADLIBOP *operator) { return ((operator->lastsignal[0]+operator->lastsignal[1])*adlibch[channel].feedback); //Calculate current …

Stretch wrote: Does Nuked OPL3 emu have a rockbox port? Would it be faster than dosbox or MAME OPL on portable audio players? No, it doesn't. And my emulator slower than DOSBox and MAME, i haven't done any big optimizations in code, because my goal is accuracy to real YMF262.

Thanks for clarifying that! Now, when you say "ymf724 doesn't support FM on PCI range" did you mean "PCIe range", right? Otherwise it would mean that the ymf724 doesn't support its included FM chip even on a regular PCI slot![/quote] PCIe allows only ports >= "card base address",unlike PCI. 724's FM …

So how come the chip be registered at the right address and still not get detected? Would it be possible that somewhere in the PCIe to PCI connection the card is losing the ability to send or receive data through the FM port? Also, considering that the kernel does load the gameport without a …

Is your MIDI sequencer x64 application? x64 apps can't use 32bit user mode MIDI drivers(like MUNT, OPL3). LoopMIDI is kernel mode driver, so it works with both 64 and 32 bit apps. You either should switch to 32 bit version of your app or build x64 version of MUNT.

Nice to hear that it works. You have to change only 0x388 , don't change any 0x220 values. Sorry. But i don't remember anything about these drivers.

I based schematic on midibox fm board. I have arduino mega 2560. I connected opl3 pins directly to arduino. Then i wrote simple sketch that recieves opl command through usb and patched dosbox to support arduino board. And it works. Sample: https://youtu.be/5Vf9jfgKBrY
