Re: DOSBox-X branch

Posted on 2023-09-04, 05:59

I recently downloaded and installed the May 2023 release of DOSBox-X (Windows SDL1) and have a question about the PC speaker settings. I am wondering why it defaults to the rate of 65536 in the conf file that is generated when I performed a fresh install of DOSBox-X? In the wiki it says the default …

This issue was brought up in the DOSBox-X issue tracker and I have an analysis of what is causing the black lines. The game is not using any segment limit or page fault tricks. Instead when copying scanline by scanline to video memory it seems to rely on a quirk with SVGA bank switching where the …

Can you compile from the …

Attached is code to implement a gamma level modifier in the 3dfx Voodoo emulation (non-opengl software path only), as in DOSBox-X. It likely requires manual application of the patch since it was formed in a modified build. It also has a feature that implements a gamma level for non-3dfx cases where …

I am testing the recent patch for an increased baud rate on a serial port. Since it may affect the modem emulation: static Bitu INT14_Handler(void) { .. switch (reg_ah) { case 0x00: { ... Bitu baudrate = 9600; uint16_t baudresult; Bitu rawbaud=(Bitu)reg_al>>5; if (rawbaud==0){ baudrate=110;} ... …

Browsing through Staging's git repository, I see some code cleanup and unit test commits but nothing about muting of audio in the background. I regularly visit their Discord server, I went ahead and asked them about the muting fix.

Concerning my earlier post about DOSBox-X muting itself when minimized or running in the background, DOSBox Staging has recently fixed this problem with their fork. I can now listen to MIDIs playing in the background when running Windows 98 on DOSBox Staging without it muting or stuttering! Now if …

@TheGreatCodeholio: Thank you for responding. I'm not sure if you missed my post from a couple of years ago, but it seems like the Intellimouse works with a challenge/response type of system. When first queried, the mouse should respond as a standard Intellimouse, then when challenged, it should …

Nope. As far as I can tell, the Standard PS/2 mouse driver just uses INT 15h PS/2 functions for a callback even with IntelliPoint/IntelliMouse installed. I'm not certain whether Windows 95/98 at that point merely just buffer 3 or 4 bytes from the 3 bytes of the BIOS and read it that way, or if …

I did some testing with the Intellimouse emulation. It doesn't seem to work with Windows 98/ME because despite the fact that they do set the mouse up in Intellimouse mode, they still depend heavily on the BIOS PS/2 INT 15h functions and the BIOS callback function, which in DOSBox-X at this time does …

The main developer has been busy with his actual work, and one of the other developers stepped down, so that leaves a bit of a gap. But there are nightly releases you can download. I got a release out the day after Christmas, and I can work on it a bit more now. Can you explain how to install the …

I don't think it's HDCP, as why would a VGA to HDMI scaler add it? I think it's more that Blackmagic devices require an EXACT 5oHz PAL o4 59.97Hz NTSC signal. Any deviation and it's jusr "nope!". It's why for anything outside of those two strict numbers, the folks on System11's SHMUPS forums never …

Is the main DOSBox-X web page going to have a new release soon? I didn't read anywhere that the release schedule changed. thanks. The main developer has been busy with his actual work, and one of the other developers stepped down, so that leaves a bit of a gap. But there are nightly releases you …

I have some floppies at my mother's house for a Win98SE computer there, and they are compressed with DriveSpace. Can I use them with a Win98SE installation with DriveSpace installed? Same with Zip100 disks? It might work in Dosbox-X (honestly don't know, somebody else might chime in on that), but …

What are the correct setting(s) to use for G-SYNC? I'm using an Acer X34 (100 Hz) G-SYNC monitor and have G-SYNC enabled for Fullscreen and Window modes. When I'm running DosBox-X using OpenGL Perfect, I'm seeing about 18 FPS (Hz) at the command prompt. However, if I move my mouse around the window …
