2017.09.13 This is the latest incarnation of an emulator for the TI-99/4A. At first it was a simple text-based simulation of the TI (ti99sim-console) running under MS-DOS™. Then it was ported to OS/2 and graphics support for the OS/2 Presentation Manager was added. Later, it was ported to Windows and had sound support added. Now it's been ported to Linux and Mac OS X and more features are still being added. TI-99/Sim Features: General * Emulation of the TI-99/4A Home Computer. * Core emulator written in C for portability to multiple platforms. * Tracks the emulated CPU speed so it runs at the right speed even on the fastest processors. * Runs under Linux, Mac OS X, and Win32 (Windows 9X, Windows NT) * Speed is kept as close as possible to the actual speed of the TI. * Supports banked cartridges (like TI Extended BASIC). * 32K RAM Expansion emulation. * Save/restore the complete computer state (So you can pick up that game you were playing right where you left off). * Save/restore the contents of battery-backed RAM cartridges (Mini-Memory, Gram Kracker™, etc…) to disk when cartridge is removed. * Support for Gram Kracker™ emulation (requires actual GK GROM images). * TMS9901 emulation support. Graphics * Uses SDL for graphics, sound, and joysticks - supports X11 and Win32. * All documented modes emulated. * Full sprite support: 4 sprite per line limit / co-incidence checking / 5th sprite flag/index. * Scalable & Resizable window. * Full screen mode. Sound Support * Three voice support using native sound device. * Noise generation supported. Speech Synthesis * Access the built-in speech ROM (TI Extended BASIC). NOTE: Requires a speech synthesizer ROM dump. * Modules with external speech samples (Parsec, Alpiner, Terminal Emulator II, ...). Joystick Support * Hardware joystick support. * Emulated joystick using the numeric keypad. Disk Support * Emulation of the floppy disk controller (currently limited to SSSD and DSSD images). * Complete read/write support for floppy disks. NOTE: Requires a TI disk controller ROM dump. * Supports disk images created by AnaDisk, v9t9, PC99, and CF7+. * The disk utility can convert between formats, add, remove, and extract files. http://www.mrousseau.org/programs/ti99sim/ -- ポーラステーション http://perry0517a.blogspot.tw/ --
