Heres a new version of the MAME Emulator for Windows:

It’s the day you’ve been eagerly awaiting all month: MAME release day! MAME 0.198, our May release, is packed full of improvements in lots of areas. Newly supported arcade games include the rare video pinball game Tom Tom Magic, Jikkyou Powerful Pro Yakyuu EX ’98, and Keirin Ou. Newly supported computers include the TI-99/2, Dragon MSX-64, and BBC Master 512.
This release brings graphics emulation improvements to a number of systems, including more fixes for Sega Saturn/ST-V, missing effects emulated in 1945k III, and improvements to the title screen in Wolf Fang. The SH-4 recompiler now supports more FPU opcodes directly, and NAOMI keyboards are supported. Low-level floppy drive emulation improvements bring improved compatibility for Apple II software. Newly supported peripherals include a PC ISA LBA BIOS card, the Beeb Speech Synthesiser, and a number of BBC Micro pointing devices.
Other additions include new Tiger handhelds (Batman: The Animated Series, Operation: Aliens, Wayne’s World, and X-Men), the Fidelity Elegance and Prestige chess computers, and alternate versions of Battle Balls, Centipede, Final Fight, Karate Blazers, Last Mission, Real Puncher, Sengoku 3, Spy Hunter, and World Heroes 2. There are lots of additions to the Apple II cassette software list, and several additions to the Sorcerer cassette software list as well. MAME now supports Korean user interface thanks to a contribution from Neius.
For developers, we’ve fixed some issues in the debugger affecting CPUs that use word addressing, and the source list is sorted more intuitively in memory windows. We’ve made a number of changes to how machine configuration works to make driver development more intuitive and less error-prone.
