MEKA 0.62b

posted in Emulator Release by slein on Mar 17th, 2002

Meka has been updated to version 0.62b, and this time it's a public release. Here's what's new: - The Z80 core has been tweaked - Battery backed RAM is now scanned so unnecessary pages are not saved in the .SAV file - Added new entries to the checksum and compatibility lists. - Updated Spanish localisation. - Sonic Blast [GG] minor glitches on title screen in non Japanese mode has been confirmed to appear on a real Game Gear, so the game is now marked as perfectly working. - Game Gear perfect compatibility has now increased to 98.09% - Rewrote 93c46 EEPROM emulation from stratch, it now works and saves data properly. This fixes the following Game Gear games: - Majors Pro Baseball - Nomo's World Series Baseball (J) - Pro Yakyuu GG League (J) - World Series Baseball [A] - World Series Baseball [B] - World Series Baseball 95 - Emulated onboard 64 kb RAM chip of Ernie Els Golf (GG). - For the sake of accuracy, started to implement emulation of the four slighty different VDP chipsets used in Master System 1/2, Game Gear and Megadrive (compatibility mode). They all have subtle differences, causing some games not to work perfectly on all of them. - Fixed glitches in Ys (Japanese version), using 315-5124 VDP emulation. - Fix bugs Z80 emulation, letting the Game Over screen for Rambo III to appears normally - and this required many many hours of work! (Also changed behavior of EI instruction, fixing Double Dragon for Game Gear (again). - Fixed VDP refresh disable emulation for Game Gear. - Fixed YM-2413 state restoring when loading a save with FM playing. - Now store YM-2413 state initialization in VGM files. - If available, store Japanese game name (in romanji form) in VGM files. - Fixed shifted instruction offset in debugger. - Updated TECH.TXT with instructions about how to build a DB-9 adapter to connect SMS Joypads on your PC. - Added full French (by Overture 1928) and Swedish (by Henrik Sankala) localisations. Complete Italian localisation (by Andra Ballandino). - Fixed minor display bug in the Inputs configuration tool. You can pick it up at our Sega Master System & Game Gear Emulators page.
