Sorry to revive an old thread! Indeed. ED: 3,5" 2,44MB HD: 3,5" 1,44MB or 5,25" 1,2MB DD: 3,5" 720kB or 5,25" 360kB SD: ??? SD and DD disks are the same thing. (What?!) SD means that the disk is formatted with FM (Frequency Modulation) encoding. DD means that the disk is formatted with MFM (Modified …

I know that DOSBox doesn't like Lemmings, so don't groan. I've already read Bradr's excellent explanation of the in-frame palette switching that the DOS Lemmings games perform on VGA graphics cards in Mode D in order to display more than 16 colors per frame ( https://www.vogons.org/viewtopic.php?t= …

Cool. There are no batch files in the copy of ninja2.zip at http://www.oldskool.org/guides/tvdog/games.html. If you can provide a link to a copy that has the batch file, I'll try it out!

Sorry to revive a very old thread. I tried to email you (Ryune) at the address listed on your website, but it was returned undeliverable. I think there might be enough public interest to justify posting this here instead of contacting the OP privately. I hope you subscribed to the thread! @Ryune: …

Impressive analysis, cfoesch! If someone coded MMX emulation for DOSBox, I'm sure it would end up in the mega builds, but I wanted to point out that there are DOS games that use MMX for one reason or another, which might justify inclusion in the official build. At any rate, thanks for the …

Yes, it would be counterproductive to emulate instructions that aren't needed in the name of speed, since emulating them would actually be slower. I'm not sure if MMX does anything that can't be done without MMX on JF:FB, so that may not be a great example. I'll see if I can find an example of a DOS …

The Need for Speed won't run in SVGA mode unless it detects a Pentium processor. NFS doesn't require a Pentium processor, but DOSBox's ability to report a Pentium CPUID allows you to take full advantage of NFS (thank you for adding that feature). I don't know if MMX improves the graphics/unlocks any …

I know that the policy is not to add anything to DOSBox unless a DOS game needs it, and I had always thought that there were no MMX DOS games. I was going through my recent acquisitions today and found an "Designed for Intel MMX" logo with the text "Enhanced for MMX equiped computers" on JetFighter …

I've tried booting Windows 98 SE in every major DOSBox build and most of them get nowhere. MB6 was able to get to the desktop briefly before crashing, but only once. Do I need "First Edition"?

Yes, let's not get carried away. He's only porting DOSBox to Java. The extent to which he's "generally trying to get it to run as much stuff as possible" is that he's including some of the extra stuff from Megabuild 6, and he's making sure that it runs unofficially supported stuff like Windows 98. …

Interesting. I wonder why Windows 98 would boot in DOSBox when Windows 95B and C have failed me for so many years. At any rate, the author of jDosbox is incorporating stuff from Megabuild 6, and generally trying to get it to run as much stuff as possible.

It would actually be kinda cool if there was a custom build of DosBox designed specifically for running Win95. 1) It doesn't seem to be necessary. Windows 95 under DOSBox works great for me! and 2) There is one! jDosbox is a Java port of DOSBox. The author tests each commit for compatibility with …

I'm just using standard DOSBox 0.74 at the moment. Everything I've tried to run has worked so far, but I'll remember your warning about Direct3D if anything doesn't work in the future. Thanks for the heads up.

There may very well be a patch for all of them, but a patch is unnecessary if you just use Windows 95. Windows 95 runs too slowly for me under Bochs, and I've never been happy with the experience under VirtualBox and Virtual PC. The experience of running Windows 95 games under DOSBox is the same as …

DirectX 5 installs and works great! Old DirectX games just don't work under Windows 7 x64, even in Compatibility Mode, and Windows 95 under VirtualBox and VirtualPC is flaky at best. DOSBox is officially the best way to play old Windows 95 games!
