- MD: Fixed glitches and hang in the Europe release of "Donald in Maui Mallard" - PC-FX: Expanded external backup memory from 32KiB to 128KiB, to match the amount of memory in an FX-BMP - PC-FX: External backup memory will now be saved to/loaded from its own file, instead of being appended to the internal backup memory in the same file. For backwards compatibility, there is support for initially loading data from a combined 32KiB+32KiB file; however, the additional 96KiB of external backup memory will be unusable by the game in this case due to existing filesystem structures - SASPlay: Added support for "Air Walkers" - SNES-Faust: Added mouse emulation - SNES-Faust: Fixed color math glitch in "Final Fantasy V" when Exdeath is holding the opaque white sphere party hostage - SNES-Faust: Fixed broken ExLoROM support, used by a "Heartthrob Memorial" translation patch - SS: Added experimental support for ST-V games that don't require decryption chips or special hardware. Refer to the ST-V section of the documentation for more details and a list of explicitly supported games - SS: Fixed missing and glitchy graphics in "Houkago Ren'ai Club: Koi no Etude" - SS: Fixed graphical glitches in "Radiant Silvergun" at the start of a new game begun after interrupting the attract mode, or game over, while a fancy rotating background was present, such as during the AKA-O battle
