2017.07.29 NeoGensPlusGX is a multicore emulator which emulates: Sega Genesis/Megadrive, 32X, SegaCD/MegaCD, Sega Master System, Game Gear, SG-1000, SC-3000, SF-7000, MK3. NeoGensPlusGX v1b06 Public Beta Changelog: * Updated to madmab edition interface CFv1b27. See "Interface Changelog.txt" * Fixed up detection of redump.org images some more (grrrr). * Game SFX volume is no longer saved with non CD game configurations for both cores. * Some tweaks to the allocation/deallocation of various things to help allieve some memory issues (and crashes) for those using the PM3 skin. I personally recommend dumping the PM3 skin, it is a memory hog. ************************** * Genesis Plus GX v1.12b * ************************** * Core updated to all changes up to 06/30/17. See below changelog. [Core] * When copying backward, use memmove instead of memcpy. [Core/CPU] * improved 68k auto-vectored interrupts acknowledge cycle timings accuracy (fixes background color corruption in Bubsy). * fixed Z80 interrupt duration (fixes music running too fast in Bomb on Basic City homebrew). * fixed 68k cycle counter Power-ON value (verified on real hardware). * fixed 68k undocumented behaviors for ABCD/SBCD/NBCD instructions (thanks to flamewing for his test ROM). * minor optimization to 68k read/write handlers * removed stack access optimizations to prevent unintentional (or intentional) ROM corruption [Core/IO] * improved XE-1AP controller emulation. * improved control pad emulation (verified on real hardware). * fixed 4 Way-Play adapter compatibility mode (fixes multitape detection in CD games). [Core/Sound] * improved PSG accuracy (fixes high-frequency aliasing noises in Captain Silver, Kenseiden, Phantasy Star & many other SMS games, thanks to Enik for the help). * optimized Blip Buffer implementation for stereo streams (thanks to David Knight for original idea). * rewrote PSG core from scratch & replaced deprecated "PSG boost noise" option with optional Hiqh Quality PSG resampling. * improved accuracy of SN76489 core. * fixed YM2612 LFO PM implementation (block & keyscale code should not be modifiedby LFO). * fixed Timer B overflow handling. * minor YM2612 optimization. * fixed PSG power-on latched register (verified on VA4 MD1 hardware) [Core/VDP] * confirmed register $0A default state on reset. * fixed spurious 8K-16K VRAM switching when reloading SG-1000 context + minor optimizations. * fixed Master System II extended video modes sprite parsing (fixes Mega Man 2 demo). * fixed issues caused by screen width change during active display (Golden Axe 3 intro, Ultraverse Prime). * improved VDP status timing accuracy. * fixed Mode 4 sprite Y wrapping in various screen height modes (fixes VDP Test ROM / Fantastic Dizzy). * disabled sprite rendering during border when borders are not disabled (fixes wrong sprite collision detection in Racer homebrew game when borders are disabled). * fixed first frame VINT occurrence. * improved FIFO emulation accuracy * improved DMA timing accuracy during blanking (verified on real hardware by Mask of Destiny) [Core/CD] * minor changes to CDD status codes. * fixed AUDIO tracks length calculation when using separated files (WAV/OGG/BIN) with INDEX pause defined in CUE file. * fixed bootable cartridge (mode-1) corrupting loaded CD BIOS. * increased CD dive latency (fixes Earnest Evens). * improved PAL Mega CD timing accuracy. * CD struct area should only be touched when emulated since it's shared with large ROM (> 8MB) buffer area. * improved CDD "play" command accuracy (fixes "Snatcher" Act 2 starting cutscene). * CD timings should be initialized during CD hardware initialization (fixes broken Mode 1 support). * fixed access to Sub-CPU "read-only" communication registers (fixes Round 5 Boss freeze in Streets of Rage / Sega Classics Arcade Collection). * fixed WAV file detection to support files generated by Audacity/FFmpeg/libavformat with RIFF header metadata chunks. [Core/MD] * fixed regression introduced with first version of SF-001 mapper. * improved I2C EEPROM boards emulation. * fixed large ROM (> 8MB) loading accidentally enabling CD hardware emulation. * fixed incorrect I2C EEPROM board detection for SRAM-patched hacks (Wonder Boy in Monster World, Megaman - The Willy Wars / Rockman Mega World). * Correct fix (ROM type field is actually not part of product code). * enable official bank-switching mapper by default (fixes Sonic VR hack). * improved SVP memory handlers accuracy (fixes Virtua Racing debug mode). * fixed SRAM initialization for Sonic 1 Remastered hack. * fixed SRAM header date. * adjusted ZRAM access wait-state delay (fixes Puyo Puyo 2 option menu exit). * fixed 68k read memory handler [Core/MS] * fixed 4MB ROM support * improved Japanese Master System I/O chip (315-5297) emulation (verified on real hardware by Charles MacDonald). [Core/SG-1000] * added support for Star Soldier & Pippols SMS Power dumps. ********************** * Neogenesis v25.18b * ********************** * Fixed issue where on bin/cue or Redump Sega CD games.. When pausing the game in game (start) and un-pausing the game then the music would not unpause. (examples are: Heart Of The Alien, Batman Returns, Ecco 1 and 2, Earth Worm Jim Special and Eternal Champions) * Fixed long standing issue where on cue/iso/mp3 Sega CD games running on a share.. When pausing the game in game (start) and un-pausing the game then the xbox would hang (stuck in a loop). This one goes waaaay back. (examples are: Heart Of The Alien, Batman Returns, Ecco 1 and 2, Earth Worm Jim Special and Eternal Champions) http://www.1emulation.com/forums/topic/35435-neogensplusgx-v1b02- public-beta-pier-solar-rom-and-cd-new-update/ https://goo.gl/LhEung -- ポーラステーション http://perry0517a.blogspot.tw/ --
