NTVDMx64 by leecher1337 - 20.10.2023 (Built by Enderman) Networking functions of VDMREDIR.DLL & OLE2 support included. Available in all flavours and locales. There are various "flavours" of NTVDM that can be built: • old-src [!DO NOT USE!] The original NT4 NTVDM. Maybe the easiest version to build, but it doesn't have multilanguage and lacks some features like LFN This has been the default repository until Feb/2020 where development has been switched to MINNT tree. This build method therefore is DEPRECATED in favour of the MINNT build systemand will not receive any future updates! This build is left unmaintained and unchecked, so don't complain if it doesn't build anymore. Please note that you need Windows XP for building. Build instructions in: doc\old-src.txt • HAXM Instead of using the emulated CCPU, it uses HAXM VT-x hardware accelleration (CPU needs to support it), so it is significally faster in textmode. But it will probably never support graphics, as it is technically impossible to emulate a real VGA card with sufficient performance on VT-x Works with minnt and old-src build. Build instructions in: doc\haxm.txt • MINNT This is the most recent NTVDM source code, it supports multiple languages, but is probably harder to build. It is planned to continue development on this source tree as of Feb/2020 Build instructions in: doc\minnt.txt There are 2 CPUs available at the moment: CCPU - The emulated software CPU (default) HAXM - The VT-x hardware accellerated version, needs supplied driver Read haxm.txt for details and advantages/disadvantages If unsure, CCPU is recommended. There are 2 types of builds available: chk - Checked, unoptimized debug build (default) fre - Free, optimized release build Free build doesn't have any debugging support, but is faster. So depending on whether your want to debug the NTVDM or want better performance, choose the appropriate build. The filename scheme for the appropriate build is autobuildd-CPU-BLD.cmd Thank you for downloading from Enderman! https://enderman.ch
