And how do you propose doing that during the install phase of Windows 95? Their installer doesn't exactly have a full Win32 environment open during the initial setup phase to run daemon tools :) In fact I once picked it apart to find that the installer is basically a Win16 app and the DOS stub runs …

So far all FreeDOS testing is carried out within VirtualBox or on real hardware using a "Linux on a stick" USB pen drive. I can definitely say that FreeDOS 1.0 has it's share of weird quirks and components that don't work correctly. You wouldn't want to use LBACACHE under VirtualBox for example, …

Errrrr.... you're right. Why did I put it under a subfolder named "dosbox-x"? I should have created a folder named "doslib" and put it under there. It was 4 in the morning when I posted that... sorry for the confusion.

I am releasing the latest revision (build 1392) of the DOS source code library. This fixes some issues I found while testing the source code against some new scenarios and while filming the code running on various hardware (I will be releasing a video when I have time on the 8042 keyboard controller …

Don't bother with IDE emulation. That would be double work as that has been written before. The tools you are writing sound pretty interesting. Too late already started :) I've written low-level C and ASM code to work with IDE controllers before, so I have a fairly accurate idea what I/O and …

As long as the "cool stuff" benefits gaming then there is no issue. For the "cool stuff" that doesn't then it won't. But it isn't as easy as just adding it and being done. Alot of testing would have to be done. No problem. I maintain this as my own branch for my hobby programming needs. I don't …

DOSBox supports PS/2 mice, so if you use a serial mouse can you use it in games that support two mice? Well at the moment the mouse input would sent the same movement data to both ports, so there's not much of a point using both even if they did. I want to point out though DOSBox 0.74 mainline does …

I figured my port was out of place on another thread about GUS emulation patching, so I thought I'd start this here. This is a branch of DOSBox 0.74 that I have been working on and off for the past 8 months. I've been modifying a lot in the source to make the emulation more accurate, to fix other …

Alright I have some interesting findings for you. I just found out that on a GUS MAX card I obtained from ebay, the Ultrainit software will give you the same result. Obviously it can see the card and initialize it to some degree (enough to make a slight "pop" sound in the speakers) but it gives the …

Finally, whether or not a DPMI server is present doesn't seem to matter. Or else, it doesn't like CWSDPMI.EXE. I thought that might matter because it refers to INT 31h which is how you call DPMI.

I also read reviews on the game as well as the history as told by the developer. It sounds like the game is crashy because the game actually is crashy on real hardware too. The developer's history log suggests it came about because of incomplete programming and Take Two cutting it up to make a sale. …

Almost forgot. Exiting to DOS is also a long painful wait. And running the game in Windows 95 DOS mode with 16, 24, 32, 48, and 64MB of RAM always results in the "invalid selector type 0" message.

Updates on Battlecruiser 3000: If no VESA BIOS is present: Game starts up, hangs with PC speaker left on (BEEEEEEEEEEEEEP). Which means the lame ass programmer couldn't be bothered to exit to DOS cleanly with "VESA BIOS not found". Durrh. With >= 64MB of RAM, whether within Windows 95 or not, the …
