Java MegaDrive/Genesis Emulator

jEnesis v0.0.4  (2006-05-07)

 

- fixed overlapping operator pixels (Vectorman 2 baloon sprites)

- rendering switched to LWJGL with enormous speed increase in scaled modes and using VSync in fullscreen mode to avoid Java timing issues

- fixed ROXL and NEG flag bug, making a lot more games work properly

- Made M68000 Reset instruction not having any effect (fixed Dragon's Revenge..)

- M68000 TAS write cycle is ignored now (Gargoyles)

- fixed Illegal Instruction Exceptions (Dyna Brothers 2, Heavy Nova...)

- fixed Move Instruction timings (Sailormoon Intro bug)

- fixed window behavior in certain situations (Mario Andretti Racing, World Championship Soccer 2, M1 Abrams Battle Tank...)

- added window granular clipping (Dragon Ball Z)

- improved Motorola 68000 - Zilog Z80 responiveness

- added Cpu freezing during DMA and DMA busy flag emulation (fixing Galahad, Eternal Champions, Street Fighter Games, F1 World Championship and many others...)

- more accurate Interrupt timing and HVCounter (Panorama Cotton, Burning Force, Galahad, Lotus 1+2 and others)

- fixed DMA fills again (Landstalker)

- made VDP emulation more accurate, also showing mirrored sprites in Castlevania now.

- added VDP window bug emulation

- added VDP invalid horizontal scroll size emulation

- Added Sprite Overflow and Sprite Collision flag emulation

- Corrected sprite pixel overflow setting in too early (Flink)

- Sprite masking documentation seemed not to be precise, so i experimented a bit, and changed it. It now works like in the big 2... and Majikaru Hashito no Butsutobi Turbo! Daibouken has feet now... yeah

- Fixed 128*64 Background Layers (Barkley Shut Up and Jam, Dragon Slayer 1+2 - Legend of Heroes)

- Fixed SRAM detection if not declared in the rom header (NBA JAM TE, Blockbuster Competition 2, Buck Rogers...)

- Added emulation and detection of the X24C01 EEPROM. (Wonderboy in Monsterworld, Megaman can be saved)

- Added emulation and detection of the X24C02P EEPROM. (NBA JAM can now be saved)

- Added new icon indicating that a game uses an EEPROM

- Made Rom validation a bit less restrictive, allowing more beta and unlicenced games to boot

- Display name of the game now gets detected depending on the region of the game. If it seems "unreadable", the filename gets displayed

- Added support for.gen roms

- Added .7z support for normal loading of a rom, as well as for the "Browse Zip" option, which therefore got renamed to "Browse Archive". The support for solid .7z archives might still be a bit buggy! I also cant guarantee that it can open every .7z archive atm. There is also support for plain .lzma files through the "Open Rom" dialog.
