---------------------------------------------------------------------------- Genesis Plus ---------------------------------------------------------------------------- Version 1.2a by Charles Mac Donald WWW: http://cgfm2.emuviews.com additional code by Eke-Eke WWW: http://gxdev.wordpress.com/ What's New ---------- see CHANGELOG Features (NEW!) --------- * cycle-accurate CPUs emulation & synchronization (68000, Z80, YM2612, SN76489) * cycle-accurate VDP emulation (DMA, FIFO, HV interrupts, HBLANK,…) * original frequency YM2612 emulation (High Quality FM) * basic hardware latency emulation * full overscan area (horizontal & vertical colored borders) emulation * TMSS BIOS support * PICO hardware support (experimental) * 3-buttons & 6-buttons controllers * Sega Team Player & EA 4-Way Play multitap adapters (up to 8players !) * Sega Menacer & Konami Justifier lightguns * Sega Mouse & Sega Mega Mouse * SVP DSP (Virtua Racing) * J-Cart * backup RAM (parallel SRAM/FRAM and serial EEPROM) * ROM bankswitch (Super Street Fighter 2) * SRAM switch (Phantasy Star 4, Legend of Thor, Sonic the Hedgehog 3) * ROM mappers & copy protection devices used in many unlicensed/pirate cartridges Usage ----- The Windows version runs windowed in a 16-bit desktop with NO sound or joystick support. The DOS version has most of the functionality from SMS Plus, such as audio, joysticks, etc. Windows/DOS controls: Arrow Keys - Directional pad A,S,D,F - 1P gamepad, buttons A, B, C, Start Tab - Hard Reset Esc - Exit program F7 - Load Savestate (game.gpz) F8 - Save Savestate (game.gpz) F9 - Toggle CPU clock: PAL(50hz)/NTSC(60hz) F10 - Soft Reset F11 - Toggle Player # (keyboard/mouse) DOS only: End - Exit program F1-F4 - Set frameskip level (F1 = no skip ... F4 = skip 3 frames) F5 - Log 68k memory access (for debug ONLY) F6 - Log messages (for debug ONLY) WIndows only: End - Exit program F1-F4 - Set frameskip level (F1 = no skip ... F4 = skip 3 frames) F5 - Log messages (for debug ONLY) F6 - Toggle Turbo mode The mouse can be used for lightgun games, PICO games and when the Sega Mouse is activated. A SRAM file (game.srm) is automatically saved on exit and loaded on startup. DOS details: You can only support a second player if you are using a joystick driver that supports more than one joystick. (e.g. Sidewinder, dual pads, etc.) Type 'gen -help' on the command line for a list of useful options. -res set the display resolution. -vdriver specify video driver. -depth specify color depth. (8, 16) -scanlines use scanlines effect. -scale scale display to full resolution. (slow) -vsync wait for vertical sync before blitting. -sound enable sound. (force speed throttling) -sndrate specify sound rate. (8000, 11025, 22050, 44100) -sndcard specify sound card. (0-7) -swap swap left and right stereo output. -joy specify joystick type. Here is a list of all the video drivers you can pass as a parameter to the '-vdriver' option: auto, safe, vga, modex, vesa2l, vesa3, vbeaf Here is a list of all the joystick drivers you can pass as a parameter to the '-joy' option: auto, none, standard, 2pads, 4button, 6button, 8button, fspro, wingex, sidewinder, gamepadpro, grip, grip4, sneslpt1, sneslpt2, sneslpt3, psxlpt1, psxlpt2, psxlpt3, n64lpt1, n64lpt2, n64lpt3, db9lpt1, db9lpt2, db9lpt3, tglpt1, tglpt2, tglpt3, wingwar, segaisa, segapci, segapci2 You can put any commandline option into a plain text file which should be called "gen.cfg". Put one option per line, please. Command line options will override anything in the configuration file. Currently the zip loading code can manage a zipfile where the game image is the first thing in it. If you try to open a huge archive of games, only the first will be played.
