Saturn emulator, for Debian, Dreamcast, Linux, Mac OS X and Windows.

0.7.2 -> 0.8.0

cart:

- Moved Netlink code to its own file: netlink.c

- Improved Netlink AT command handling. Most games using the X-Band software should work now.

- Fixed a number of bugs that were causing strange behaviour in Netlink emulation.

- Added Modem states. Online Mode is now handled correctly.

- Added Networking code that allows two Yabause instances to communicate with each other. Still somewhat buggy.

cd block:

- Fixed an issue where games that didn't specify an index along with the track when playing cd audio didn't work correctly.

vdp1:

- Code cleanups.

vdp2:

- Code cleanups.

- Adjusted frameskip code so it skips up to a maximum of 9 frames at a time.

direct sound core:

- Fixed a bug that was screwing up the buffer position. Now it's almost perfect(at the very least there's no clicks or pops anymore).

sdl sound core:

- Fixed a bug that was screwing up the buffer position. Now it's almost perfect(at the very least there's no clicks or pops anymore).

software video core:

- Polygon drawing improvements

- Removed the silly y-axis clipping technique

- Added a filter for clipping detection

- Added vdp1 "end codes" in textures, but didn't find a game that use it yet, please report bugs.

- Code Cleanups

- Fixed a potential bug in polygons

- Fixed a bug in polygon clipping

linux port:

- Code cleanups

- Changed a few things in configure script to fix compilation problems when OpenGL and/or gtkglext were not present.

- Added a log popup window.

- Added a screenshot window on gtk port.

- Fixed Pause/Screenshot bug.

- Removed the "Keep ratio" setting as it can't be done in gtk and replaced it by a "Fullscreen" setting.

- Added a yabause entry in gnome and KDE application menus

- Changed configure script so it fails on linux if --with-opengl is used and gtlglext is not installed.

dreamcast port:

- Compiles and runs again.

- Added Normal Sprite support.

- Added Distorted Sprite support.

- Added Scaled Sprite support.

- Added in YabauseGetTicks support.

- Ported VDP2 portion of software renderer.

- Added new cd core.

- Added very simple GUI.

- Other bug fixes.

netbsd port:

- Added patch to get yabause working on netbsd with cd support thanks to Takashi Kyohara.

windows port:

- Added pad configuration(first pad only).

- Added support for gamepads/joysticks.

- Removed duplicate cd code.

- Added a separate thread for cd access. SPTICDGetStatus is the only function making use of it for now.

- Fixed fullscreen bug

- Added dialog and settings saving/loading for Netlink stuff(disabled for now).

- Other bug fixes.

general:

- Commited mac port fix by Antime.

- Coordinate Increment Registers are now set to 1 when using the quick load function. It seems there's at least one game out there that doesn't want to set it.

- Improved Backup Ram bios emulation functions. The only functions that still aren't functioning correctly are Bup Write, Bup Read, Bup Verify, and Bup Set/Get Date. So still no saving, but at least there's no errors when running games now.

Version 1.54 (December 23rd, 2006)

----------------------------------

It's been a challenging 6 months since the release of 1.53.

* We've added preliminary support for NSM, Wico, and LTD. LTD is closest to working for these newly supported systems.

* Also, a minor correction for the display properties - the off state can now be set like the other levels.

* Nuova Bell is now playable with sound - needs improvement

* Thanks to Mike McAndrew for providing the correct sound rom for Rat Race.

Multi-system emulator

December 24, 2006 - Mednafen 0.7.1 released, minor bug fixes.

 

Changes:

 

* Began work on an experimental stdio interface, see drivers/remote.cpp if you are a frontend author and can read C code, though it is disabled for now. Documentation for it will be written when it is closer to completion.

* Switched to trio_snprintf() from snprintf() in the input configuration code, this should fix problems under Windows(and any other OS with a lame snprintf() implementation) with joystick button configurations not saving properly.

* Fixed parsing of the "sounddevice" setting(it was erroneously being compared to the long, descriptive name of the driver instead of the short name).

* PC-FX: More changes.
