rpix86 version 0.12 released!

December 10th, 2013, 12:05 Posted By: wraggster

Okay, after several months, here is finally a new version of rpix86! Here is a list of the changes in this version:

• Unified codebase between the ax86 and rpix86 versions of my emulators. The Raspberry Pi -specific features are handled using compile defines, otherwise the emulation code is exactly the same in both versions.
• Implemented an option to run rpix86 without needing 4DOS.COM, by launching a game directly from the command line. This is done simply by giving the full path to the DOS exe or com file as a command line parameter to rpix86. The full path is needed because rpix86 needs to emulate the logical DOS path where the executable is started from.
• Implemented FPU (floating point unit) support. This is only implemented when running in 32-bit protected mode (using dos4gw, for example). All the games I have encountered that need FPU opcodes (for example the X-COM series games) only use FPU opcodes when in protected mode.
• Implemented experimental screen output and keyboard input code for running rpix86 in a terminal window. Note that only text mode is supported, and not all keyboard keys work as expected. This code uses the curses library for input and output.
• Implemented various game-specific fixes: REP MOVSD to Mode-X VRAM, 32-bit INSB opcode, DOS INT 21h AH=67h (set number of files) call, 486-only opcode BSWAP.
