* VARCem Virtual ARchaeological Computer EMulator.
Import of all sources.
2018-02-20 21:44:51 -05:00
* An emulator of (mostly) x86-based PC systems and devices,
* using the ISA,EISA,VLB,MCA and PCI system buses, roughly
* spanning the era between 1981 and 1995.
*
* This file is part of the VARCem Project.
*
* Joystick interface to host device.
*
Fixing typos, cleaning up some fixes, updated file header version/dates.
2018-02-22 02:53:55 -05:00
* NOTE: Hacks currently needed to compile with MSVC; DX needs to
* be updated to 11 or 12 or so. --FvK
*
Added support for MSVC14, plus added a MSVC Makefile.VS
2018-03-26 17:46:16 -04:00

Fixed some bugs and warnings. Moved the SIO files to a new sio/ folder. Added the 'version.h'stuff, added Makefile rule to generate the Manifest file for Windows. Re-worked the About dialog - it now includes more info.

MSVC: Work around a DirectX SDK issue The symbol DIDEVTYPE_JOYSTICK gets defined only if DIRECTINPUT_VERSION is < 0x700, but then all DX8 symbols are missing. This probably works just fine with mingw headers. Since it's only one symbol that's missing, we'll just define that locally

Re-worked the MVR framework to allow for custom RTC chips. Fixes EuroPC and Tosh T1000/1200. Cleaned up and re-integrated the Toshiba T1000/T1200 machines. Moved LZF files to floppy/, as that is the only module using them. Various bugfixes and cleanups here and there.
