(thanks to Haze again) + + Added primitive Virtua Racing SVP faking, so menus can be seen now. + +0.93 + * Fixed a problem with P900/P910 key configuration in FC mode. + * Improved shadow/hilight mode emulation. Still not perfect, but should be + enough for most games. + + Save state slots added. + + Region selector added. + +0.92 + VDP changes: + * VDP emulation is now more accurate (fixes flickering in Chase HQ II, + Super Hang-On and some other problems in other games). + * HV counter emulation is now much more accurate. Fixes the Asterix games, + line in Road Rash 3, etc. + * Minor sprite and layer scroll masking bugs fixed. + + Added partial interlace mode renderer (Sonic 2 vs mode) + * Fixed a crash in both renderers when certain size window layers were used. + + Added emulation of shadow/hilight operator sprites. Other shadow/hilight + effects are still unemulated. + + Sprite emulation is more accurate, sprite limit is emulated. + + Added "accurate sprites" option, which always draws sprites in correct + order and emulates sprite collision bit, but is significantly slower. + + Emulation changes: + * Improved interrupt handling, added deferred interrupt emulation + (Lemmings, etc). + + Added serial EEPROM SRAM support (Wonder Boy in Monster World, + Megaman - The Wily Wars and many EA sports games like NBA Jam). + + Implemented ROM banking for Super Street Fighter II - The New Challengers + * Updated to the latest version of DrZ80 core, integrated memory handlers + in it for better performance. A noticeable performance increase, but save + states may not work from the previous version (you can only use them with + sound disabled in that case). + + SRAM word read handler was using incorrect byte order, fixed. + + Changes in Cyclone 0.0086: + + Added missing CHK opcode handler (used by SeaQuest DSV). + + Added missing TAS opcode handler (Gargoyles,Bubba N Stix,...). As in real genesis, + memory write-back phase is ignored (but can be enabled in config.h if needed). + + Added missing NBCD and TRAPV opcode handlers. + + Added missing addressing mode for CMP/EOR. + + Added some minor optimizations. + - Removed 216 handlers for 2927 opcodes which were generated for invalid addressing modes. + + Fixed flags for ASL, NEG, NEGX, DIVU, ADDX, SUBX, ROXR. + + Bugs fixed in MOVEP, LINK, ADDQ, DIVS handlers. + * Undocumented flags for CHK, ABCD, SBCD and NBCD are now emulated the same way as in Musashi. + + Added Uninitialized Interrupt emulation. + + Altered timing for about half of opcodes to match Musashi's. + +0.80 + * Nearly all VDP code was rewritten in ARM asm. Gives ~10-25% performance + increase (depends on game). + * Optimized 32-column renderer not to render tiles offscreen, games which + use 32-column display (like Shining Force) run ~50% faster. + + Added new "Alternative renderer", which gives another ~30-45% performance + increase (in addition to mentioned above), but works only with some games, + because it is missing some features (it uses tile-based rendering + instead of default line-based and disables H-ints). + + Added "fit2" display mode for all FC gamers. It always uses 208x146 for + P800 and 208x208 for all other phones. + + Added volume control for Motorolas (experimental). + + VDP changes: + + Added support for vertical window (used by Vapor Trail, Mercs, GRIND + Stormer and others). + + Added sprite masking (hiding), adds some speed. + + Added preliminary H counter emulation. Comix Zone and Sonic 3D Blast + special stage are now playable. + + Added column based vertical scrolling (Gunstar Heroes battleship level, + Sonic and Knuckles lava boss, etc). + + Emulation changes: + + Re-added and improved Z80 faking when Z80 is disabled. Many games now can + be played without enabling Z80 (Lost Vikings, Syndicate, etc), but some + still need it (International Superstar Soccer Deluxe). + * Improved ym2612 timers, Outrun music plays at correct speed, voices in + Earthworm Jim play better, more games play sound. + * I/O registers now remember their values (needed for Pirates! Gold) + + Added support for 6 button pad. + + Changes in Cyclone 0.0083wip: + + Added missing CHK opcode (used by SeaQuest DSV). + + Added missing TAS opcode (Gargoyles). As in real genesis, write-back phase + is ignored (but is enabled for other systems). + + Backported stuff from Snes9x: + * Fixed Pxxx jog up/down which were not working in game. + + Added an option to gzip save states to save space. + + The emulator now pauses whenever it is loosing focus, so it will now pause + when alarm/ponecall/battery low/... windows come up. + - Removed 'pause on phonecall' feature, as it is no longer needed. + + Video fix for asian A1000s. + +0.70 + * Started using tools from "Symbian GCC Improvement Project", which give + considerable speed increase (~4fps in "center 90" mode). + * Rewrote some drawing routines in ARM assembly (gives ~6 more fps in + "center 90" mode). + * Minor improvement to 0 and 180 "fit" modes. Now they look slightly better + and are faster. + * Minor stability improvements (emulator is less likely to crash). + + Added some background for OSD text for better readability. + + Added Pal/NTSC detection. This is needed for proper sound speed. + + Implemented Reesy's DrZ80 Z80 emu. Made some changes to it with hope to make + it faster. + + Implemented ym2612 emu from the MAME project. Runs well but sometimes sounds + a bit weird.
