Here is a recording of my OPL2LPT performing the music from Doom2 Map10. I used the Doom OPL3 driver in OPL2 mode, which is the default mode of operation, and I configured the LPT driver to go into OPL2LPT mode to help prevent strange glitches during playback. https://drive.google.com/open?id= …

I just added OPL2LPT mode to my LPT driver. The driver still defaults to OPL3LPT mode, but I added OPL2LPT mode for people who have OPL2LPT bords and wish to use this driver.

To disable the emulation, go into the configuration utility and go into hardware OPL options by pressing 4, go to the Silent emulation mode setting by pressing 2, and press 1 to enable it. I updated the configuration utility with OPL3LPT stuff after I released this test build, so there will be …

That is interesting, because I am using a function I found on a github issue that writes to the OPL3LPT. I modified it to work with inpout32.dll, so I am not sure what I am doing wrong.

I added OPL3LPT support to my user mode OPL3 MIDI driver via inpout32.dll. I don't have an OPL3LPT, so can one of you install the driver to test it? Here is how to test it. You need inpout32.dll in C:\Windows To enable OPL3LPT support, set oplhwsupport environment variable to "-lpt". Enter the I/O …

This is a bit off topic, but my OPL3 user mode driver can now change the address where it looks for an OPL chip. https://github.com/datajake1999/OPL3EMU/releases/tag/1.0.5 Can someone please test it with an OPL3LPT and post the result? I have tested my CMI8738, and that works very well, but I wonder …

Here is my WAV file writer for OPL3 emulation, as well as a VGM logger and code for writing to hardware OPL3 using inpout32.dll. Edit: Added code for a silence generator. Edit 2: Added code for audio processing. This is useful for basic DAC emulation and channel manipulation.

According to Wikipedia, the YMF262 was released in 1988,. This means that a 100% perfect OPL3 emulator was released on the YMF262's 30th anniversary. Interesting.

I modified oplclone to write to my CMI8738 at address 0xE050 and use inpout32.dll, so I could test it for myself. My CMI8738 produced a sine wave, so that tells me it has a real OPL3, or at the very least a very accurate clone. I thaught I would post my modified program here, if anyone is interested …

Will the OPL2LPT work on a modern computer with a parallel port? If so, how can I test the device on a modern version of windows? I am planning to get a parallel port add-on card for my custom built PC, so I want to know if the OPL2LPT works on modern systems before I buy anything.

After days of research, I figured out how to have the driver write its audio buffer to a wav file, and incorporate multiple OPL3 emulator cores. The cores I included are Nuked, DOSBox compat, DOSBox fast, and MAME. I also added VGM Logging support and hardware playback through inpout32.dll. I used …

I am looking for a midi to wav converter that uses the code from opl3windows as well. It is the most accurate compared with everything else because it emulates the pitch bend underflow bug, for example. I don't like using foobar2000 to convert midis to wav, even though it uses the code from …
