MESS v0.145 is released. MESS is an open source project which documents the hardware for a wide variety of (mostly vintage) computers, video game consoles, and calculators through software emulation, as MAME does for arcade games. As a nice side effect to this documentation, MESS allows software and games for these hardware platforms to be run on modern PCs.

MESS v0.145 Changelog:

0.145 New System Drivers Supported: ----------------------------- (none) Systems Promoted from GAME_NOT_WORKING: --------------------------------------- (none) Skeleton drivers: ----------------- - Olympia People PC [Robert aka rfka01] System Driver Changes: ---------------------- -c64: Implemented memory mapping via a 82S100 device that uses the fusemap of the real C64 PLA. This enables full cartridge support, and more accurate emulation of the hardware in the future. Retired the old driver, and separated Ultimax (vic10) and C64DTV to their own drivers. [Curt Coder] -lynx: Added basic uart loopback emulation (loopz, malibu, bzone2k, awesomeg get past intro) [Huygens] - Moved sign conversion code inside multiply function (fixes stunrun) - cartslot changed to mandatory (real lynx will not power on without a game inserted) - moved sign detection back outside multiply function. - added sign flag updating on write to LSB of MATH_CD register. -n64: DMA / RSP / RDP Optimization and Documentation [MooglyGuy] - Start of mass variable renaming / documentation in the RDP core - RSP Opt: Shunt around the core memory system for RSP instruction / data fetches - DMA Opt: Shunt around the core memory system for SP and PI DMA transfers - RDP Opt: Replace 2D switch statement with function table for texel fetching - RDP Opt: Replace 3x array lookup for 16-to-32 pixel expansion with 64K LUT - RDP Opt: Remove setters / getters in favor of direct member access Software Lists: ---------------- -ibm5140.xml: added floppy disk softlist. [Kaylee] -apple1.xml: added tape software list [Anonymous01, Fabio Priuli] -famicom.xml: added a floppy disk softlist and updated the driver to use it. [Fabio Priuli] Source Changes: ---------------- -Added Covox DAC and Covox Stereo-On-1 [Miodrag Milanovic] -Added emulation of HD64610 RTC and hooked up to pda600 driver. [Sandro Ronco] -ISA card AHA1542 skeleton added [Darkstar] -Added noise support to UPD1771 [plgDavid] -Added ISA IBM PC Music Feature Card [Phil Bennett] -ioport.c: Made the key/paste buffer auto-expand when it becomes full. This makes it possible to paste larger BASIC programs for instance. [Wilbert Pol]
