AEP Emulation Page reports that B-EM, the open source BBC Micro emulator (for DOS, Mac OS X, and Windows), has been updated to version 1.0. Below are the changes in this version.

- FDI support. Allows use of copy protected disc images. A few bugs in FDC emulation remain, however about 75% of FDI images dumped so far work.

- Improvements to timing, Joust now works, along with some Kevin Edwards protected games.

- Master Compact emulation (largely for some of the dumped FDI images).

- Slight improvements to cassette emulation, loader on Joust now works, speedup now available.

- Fixes and optimisations to ARM emulation.

December 23, 2005 - Mednafen 0.4.1 Released

The Win32 build will be updated later, sometime before the next year.

 

Changes:

 

 

Joysticks initialization is now slightly more verbose.

Fixed hash calculation in the joystick code, and added a workaround for hash collisions(which would occur if two extremely similar joysticks are used on the same system).

Video initialization is now more verbose.

The -.special command-line arguments for selecting a special scaler now take the short name of the scaler, which is found in the documentation, instead of arbitrarily-chosen numbers. However, out of the goodness of my cold, black heart, arbitrarily-chosen numbers may still be used, though it should be considered deprecated.

Example:

  -nes.special 1 (deprecated, but works, selecting hq2x)

  -nes.special hq2x (good!)

  -nes.special wombat (bad!)

 

libsndfile is now used for WAVE recording(instead of the old ugly code).

Altered the internal floating-point format used to represent audio data by changing the range to -1.0

NES: Fixed a 1-byte overflow bug in the Barcode World input device emulation code by changing a strcpy() to a memcpy().

Added a "-help" command-line option, which prints out command-line argumentsand parameters.

Fixed the configuration file loading code to exit the emulator if invalid data is in the configuration file, instead of just ignoring it and the rest of the entries, thus trashing the configuration file on exit.

Changed the default xscale and yscale settings for Lynx to 4.

Physical mouse buttons can now be assigned to virtual buttons.

The width and height of the state preview are now saved in save states, fixing a problem with broken save states if the -nes.clipsides option is used, and possibly in other situations(note that this won't fix the problem in old save states, only new ones).

Fixed a garbage(OSD stuff) problem in screen snapshots and save states when they are done after a frame that has been skipped(the solution is to delay the snapshot/save state until the next frame, which is set to not be skip).

Fixed a typo that broke the hq3x effect(it had weird graphical glitches).

Modified more settings to use the new plain-text configuration file format.
