* you can now switch between FM cores without reseting the game. FM registers value are automatically restored when switching.

2007-08-18 13:16:32 +02:00
This means you can still modify some of these options afterwards but they are now automatically set/unset when loading a game which need
special timing fixes. These fixes are also automatically desactivated when the current game doesn't need them.
2008-08-07 14:26:07 +02:00
For information, games that are actually detected and need special timings to run properly are:
2007-08-18 13:16:32 +02:00

Genesis Plus GX release 070326 (Eke-Eke)
2009-01-16 16:02:08 +01:00
---------------------------------------------------------------------------------------------------------
[Gamecube]
* added DVD automount: automatically call libogc DVD_Mount function if ISO PVD reading failed (idea taken from softdev's last neocdredux release). This may be useful for loading roms from a DVD after booting from SDLOAD or after stopping DVD motor.
* added "DVD motor off" feature, like in others emulators
* corrected Memory Card mounting function: EXI_ProbeReset() function was never called if the first mounting attempt failed. Should fix some of the "Unable to mount memory card" errors.

[Core]
* Color RAM update now always reset color 0 to border color (fix color glitches in Mortal Kombat,...) (thanks to Noop's for the idea)
[Gamecube]
* remove some rendering unused code (only used by DOS version of genesis plus) for little speedup
* added an option to enable alternate line rendering timing (fix single line error in Road Rash series and Legend of Galahad's Intro)
* added last Softdev's modifications (normalised memory access and ASM GU functions used intead of 'C' ones) for some speedup
* updated gcaram.c to be compatible with last libogc version

---------------------------------------------------------------------------------------------------------
[Core]
* little rendering code speedups
* modified HV counter tables (fix graphic glitches in Skitchin's sky, Lotus 2 Recs, Panorama Cotton, Dashin Desperados & maybe more)
* completely rewrote DMA timings emulation so that it works for all games (no more cpu freezing)
* added all DMA tranfer rates handling for each three DMA modes and added dma busy flag emulation
* modified interrupts handling on VDP register #0 and #1 writes (fix Lemmings status bar)
* added VDP RAM write latency (fix Chaos Engine/Soldier of Fortune gfx glitches)
* modified FM timers handling a bit (fix Vectorman2 music)
* corrected Sprite Limit rendering (fix Sonic 1 & Micromachines 2 title screens)
* corrected IO Registers writes (fix Decap' Attack controls, no more need for alternate input)
* corrected 6 Buttons Pad emulation (fix 6buttons detection in Mortal Kombat 3, Comix Zone and other 6-buttons compatible games)
* modified sound mixing a bit according to Generator sourcecode (FM and PSG ratios seems more correct)
* added separate CPU Region (USA, Europe, Japan,...) & Speed (PAL or NTSC) choice in menu options
* modified main frame synchro in PAL mode (fix sound glitch in this mode), thanks to Softdev for the solution
* added savestates support (go to SRAM menu, memory card supports only)

[Core]
* fm timers fixed (fix missing music in Castle of Illusion, Quackshot, Undead Line, Wonderboy in Monster Lair, Cal 50, Turbo Outrun, Thundeforce 4 and maybe more)
* added complete EEPROM emulation (save support now works fine in Wonderboy5, Megaman Willy Wars, NBA Jam...) (credits to Notaz, adapted from Picodrive code)
* added preliminar dma timing emulation (fix bottom screen in Legend of Galahad) (credits to Notaz, adapted from Picodrive code)
* hack: clear Vint pending after Hint (INT level 4) acknowledge (fix Fatal Rewind)
* hack: modify read_bus16 to return a random value (fake fetch) (fix Time Killers)
* modified cpu execution timings, with more correct hblank and interrupts timing (fix ISS Deluxe, Double Dragon 2 and certainly more) (Based on Gens code)
* modified busreq mechanism: better synchro between z80 & 68k (no need to dejitter anymore) (Based on Gens code)
* added sprite collision detection (fix Strider 2)
* modified dma fill operation for big endian platform (fix Contra Hardcorps gfx garbage)
