- you can now switch between FM cores without reseting the game. FM registers value are automatically restored when switching.
|
||||
- modified PAL framesync a little bit: the 20ms period is now applied between the start of 2 consecutive frames,
|
||||
no more between the end of the previous and the start of the next one, which seems more correct to me
|
||||
- removed the previous VINT timings modification because it brokes some games (Rocket Knight, Thunderforce III,...)
|
||||
- added automatic Timing configuration (VDP latency, VINT timing & alternate Line Timing) at game loading, based upon specific romname detection.

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.
|

|

For information, games that are actually detected and need special timings to run properly are:
|

.Legend of Galahad & Road Rash series (single line not rendered properly)

.Sesame Street Counting Cafe (don't boot)
|

.Chaos Engine/Soldiers of Fortune (graphic glitches on scrolling)

|

* added SDCARD subdirectory browsing and LFN (255 char. max) support
|
||||
|
||||
|
||||
09/03/2007:
|
||||
-----------
|
||||
- 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]
|
||||
|
||||
* 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
|
||||
|

|
||||
07/02/2007: (Eke-Eke)
|
||||
---------------------
|
||||
- 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)
