[General] * Added some color adjustments feature : - Brightness adjustement. - Contrast adjustement. - Greyscale mode. - Invert mode. Note that contrast and brightness are not calculated correctly yet. * Rewritten Gens.txt by Red5 of the Genesis Project. This is intended to be an updated/improved version of the old Gens.txt, it is not a "Gens Manual Lite" however and you will still need to download that for instructions on some of the more advanced features like Game Genie support. * Debug removed. * Screens saver is disable when Gens is running. * Modified the tiny application icon, the guy which sent me it will probably recognize it ;) (23/04/2002) Changes Gens 1.91 <- Gens 1.90 : --------------------------------------------- Changes concern only the sound emulation : * YM2612 : - Fixed a stupid bug with decay rate calculation. - Fixed the enveloppe recalculation. - Fixed the LFO in High Quality mode. - Improved the interpolation calculation in HQ mode (slower). - Fixed a bug in the reset processus. * PSG : - Fixed a bug with very high frequencies. - Fixed a bug in the reset processus. - Volume ajusted.

(09/11/2001) Changes Gens 1.30 <- Gens 1.20 : --------------------------------------------- [Sega CD] * Added the possibility to choose a perfect synchronisation emulation mode. This means that main CPU and sub CPU execute instruction by instruction then emulation is more accurate but a lot slower. This option is desactivated by default, you can enable it when you're playing Sega CD games but it's highly recommend to use it only if the game doesn't work in normal emulation mode and if your CPU is fast (>= 500 Mhz). * Fixed a (stupid) bug in the GFX rotation/scaling engine. * Fixed Word RAM decoded format (dot GFX conversion). * Added cell GFX conversion. * CDC -> PCM RAM DMA fixed. * CDD and CDC emulation improved. * Fixed the memory control register (not yet perfect). * Fixed a bug in the "Font Data" calculation. * Fixed a bug with PCM sound. * Fixed severals bugs in the MP3 decoder and streaming code. * Some others minors bugs fixed...
