Atari800 Description

An Atari 8-bit computer and 5200 game system emulator for multiple platforms. Atari800 project is an Atari 8-bit computer and 5200 game system emulator for multiple platforms.It runs on DOS, Windows, Amiga, Atari ST, Mac, and Linux/UNIX. It includes support for Atari cartridge ROMs, popular Atari disk images files, running Atari binaries directly from the host system, and accessing the host filesystem from within the emulated Atari. Here are some key features of "Atari800": · Atari 400, 800, 600 XL, 800XL, 130XE, 5200 Games System. · 130XE compatible memory expansions: 320K, 576K, 1088K. · Optional 4K RAM between 0xc000 and 0xcfff in 400/800 mode. · Cycle-exact 6502 emulation, all unofficial instructions. · Cycle-exact NMI interrupts, scanline-based POKEY interrupts. · Cycle-exact ANTIC and GTIA emulation, all display modes. · Player/Missile Graphics, exact priority control and collision detection. · Exact POKEY registers (sound and random number generator). · 8 disk drives, emulated at computer-to-drive communication and fast patched SIO levels. · ATR, XFD, DCM, ATR.GZ and XFD.GZ disk images. · Direct loading of Atari executable files and Atari BASIC programs. · 42 cartridge types, raw and CART . · Cassette recorder, raw and CAS images. · Printer support. · Files can be stored directly on your host computer via the H: device. · Current emulation state can be saved in a state file. · Sound support on Unix using "/dev/dsp". · Stereo (two POKEYs) emulation. · Joystick controller using numeric keypad. · Real joystick support. · Paddles, Atari touch tablet, Koala pad, light pen, light gun, ST/Amiga mouse, Atari trak-ball, joystick and Atari 5200 analog controller emulated using mouse. · R-Time 8 emulation using host computer clock. · Atari palette read from a file or calculated basing on user-defined parameters. · Screen snapshots (normal and interlaced) to PCX and PNG files. · Sound output may be written to WAV files. · User interface on all versions supporting bitmapped graphics. · R: device (the Atari850 serial ports) mapped to net or real serial port. What's New in This Release: New features: · added Axlon and Mosaic RAM expansions for Atari 400/800 · added emulation of 1400XL, 1450XLD, MIO and Black Box · added support of .PRO copy-protected disk images · implemented tape loading with variable bitrates · implemented cassette writing via hardware registers · added switching between NTSC and PAL color palettes · added emulation of XEP80 and a prototype 80 column card for the Atari 1090 (SDL only currently) · added emulation of CX85 numeric keyboard (Java and SDL only) · event recording added (-record, -playback): save your game walkthrough using the "-record mygame.dat" and later impress your friends by your game skills or highest score using the "-playback mygame.dat" · NTSC Filter option added to UI · -directmouse added to SDL and X11 (used for -mouse pad or koala) · monitor supports arrow keys - e.g. up-arrow for history · SDL: interpolated scanlines (use -scanlinesnoint to disable) · SDL: added -mouse, -mousespeed, -grabmouse (also Alt+M) · SDL: visual configuration of keyboard joysticks layout in the UI (F1 -> Controller Configuration -> Define layout) default mapping changed to 4,8,6,5 (joy0) and A,W,D,S (joy1) · R: device can be serial-only, network-only or both (selectable) · R: device now supported on MS Windows and Dreamcast as well · a completely new port to Java using NestedVM, running also as an applet · Falcon/TT: removed Devpac dependency in asm files (now gcc friendly) Fixes: · fix for "Ilusia" demo · better GTIA bug mode emulation · POKEY sound: nonlinear mixing (not enabled by default), two-tone filter · fixed POKEY registers: ALLPOT, IRQEN and STIMER · various Atari5200 fixes · fixed Atrax cartridge bank switching · fixed sound recording to WAV · -showspeed fixed, now shows speed
