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 has no screenshot function. ? That's very odd, but at least that's an explanation. Strangely, the note on the wiki also says video capture is not available, but it appears to work perfectly? (I'm not going to try to guess what the reasons for these things are, but I would say that crashing on use of an unsupported feature instead of it just not working or displaying a message to that effect made it more than a little frustrating to try and understand, for me.)
Is there any other more "official" SVN build available besides EmuCR? All the other ones linked in the wiki seem to have strange additions (DOSBox-X, etc.)
