  • Brian Troha updated suna16.c: Added board documentation, added PCB layouts for both styles of Back Street Soccer and Ultra Balloon. Added dipswitch locations to Back Street Soccer, Ultra Balloon and Best of Best. Changed CPU clocks to actual OSC based timing.
  • Lord Nightmare and digshadow updated tms5220.c: Based on decap analysis, both the TMS5220 and TMS5220C use identical LPC tables; get rid of the unnecessary extra table.
  • smf updated the PSX GTE: Improved FLAG calculation in NCDS, CDP, NCDT, NCCS, CC, NCS, NCT & NCCT by checking for overflow after each addition.
  • Tafoid and Shane Chaneman detailed differences in Fighting Golf (US) from parent based on observation and "SNK Program Update" notice which was found which includes a DIPSWITCH change.
  • R. Belmont updated primrag2: PCB readme shows 8MB RAM, made it so.
  • smf fixed MVMVA flag calculation & replicate the bugs when mx is set to 3 or cv is set to 2.
  • Phil Bennett updated esripsys.c: Fix regression caused by cycle-exact 6809 core.
  • smf updated the PSX GTE: fixed RTPS flags and calculation.
  • Andrew Gardner updated the QT Debugger: Adds trackpc command, allowing for a visual display of where the program counter has visited in the dasm windows. Run "help trackpc" in the debugger to see the options.

  • smf added partial support for 1f801060 for setting the RAM size, if the size is set larger than the actual memory then RAM is repeated. As a result the RAM is no longer included in the drivers memory map, you have to specify the size in the machine.

  • Andrew Gardner updated the QT Debugger: Now saves all settings for all open windows - including docks in the main debug window. Also fixes bug where closing the main window with the X in the corner didn't save settings properly.
  • Tormod updated taitotz.c: added romdumps from pwrshovl additional I/O PCB.
  • R. Belmont and Nick Boos updated OS X: Support for both OS X native and Unix-style multiuser installs.
