I've had good results with an Epiphan DVI2USB capture device. (Expect to have to do some fine tweaking of the timing settings to get a good quality picture.) In my experience with OSSC it's not very useful for capture purposes. It can't convert framerate, and I think most HDMI capture devices you …

I think I've read somewhere that ESS cards have somewhat unreliable Adlib compatibility even though they really shouldn't as it just FM synth. Maybe some games call Adlib functionality in some weird way. It has very good adlib compatibility, but it's not an exact copy. It was made to do its own …

I think the wiki has been locked for a while. When I revised that page I couldn't find a usable version of pdcurses, so it'd be nice to have some instruction there. Ultimately though after writing that guide I installed MinGW and built it with that, and had a much easier time than trying to do it …

I found a 1996 ESS Technology patent for FM synthesis. Not sure if there's anything in here that would really help this reverse engineering, but just in case it's useful (and for reference in case I need it later). US Patent 5,581,045 December 3, 1996

Alright, I think I'm finished poring over the disassemblies for now. I'm still waiting for the hardware, but I think I've learned a lot about it from just inspecting the Windows FM drivers so far. I'll leave what I know at this point here, and will get back to it when I have my hands on the actual …

Yes, Windows MIDI playback is very different, and this is actually what I'm most interested in. It has its own driver, with different patches, and responds differently to control events.

I'm very interested in this family of sound cards, especially the ESFM synthesizer. I'm trying to find information about it, but its data sheets don't really describe anything about the extra FM features over OPL3 except for mentioning 20 voices instead of 18? I also can't seem to find any attempt …

It happens to me too in VS2017, basically with any breakpoint my system drops to about 1/3 fps and most keypresses / clicks / mouse movement will be dropped. Kinda just have to rapidly tap SHIFT+F5 until it manages to resume. (Actually did a little bit of debugging like this, but it was extremely …

As a followup, I went through Building DOSBox with MinGW on the wiki, and managed to build DOSBox that way as well. There were several hiccups along the way, but I documented them on that wiki page. After going through it, I'm not sure if the MinGW way is easier or harder than doing it with VS2017, …

I'd like to create an account on the wiki, and I'm trying to follow the captcha instructions in the stickied thread, but whatever I try I get an invalid captcha response. Can anyone help?

I went through the process of figuring out how to build with VS 2017 today. Was eventually successful, but had a few hiccups. In hindsight, it probably would have been easier to install MinGW, but I didn't know until reading this thread that that was the more official way to go. If the VS version is …

I get a crash every time I try to screen capture in r4130. If this is at all useful: Unhandled exception at 0x77E8EBCB (ntdll.dll) in dosbox.exe: 0xC0000005: Access violation writing location 0x00000014. Edit: Oh, please excuse that, I didn't realize that the EmuCR build is not "official"? ...and it …
