TrueReality a software N64 emulator was updated today and multiple times in the last few months after four (!!!) years of silence.

No changelog was provided, but it should be interesting for more guys than just me.

Sega Master System / Game Gear emulator

Today, I bring you the release of CrabEmu 0.1.7. This release contains far too many bug fixes and code cleanups to mention, but here's a selection of some of the bigger changes:

 

* Modified sound output to remove branches from the code.

* Fixed a Dreamcast GUI issue where CrabEmu would crash after loading about 7 roms.

* Made the Dreamcast port only show the portion of the screen that would actually be visible on the Game Gear.

* Added a very simple VDP debugger to the Mac OS X version.

* Added a mapper detection function for certain games to detect use of special mappers by the two checksums on the rom.

* Enabled sound output on the Dreamcast port.

* Added support for the EEPROM used in certain Game Gear baseball games.

* Added support for the extra RAM in the Ernie Els Golf cartridge.

* Added support for the extra RAM in the SG-1000 game The Castle.

- More accurate emulation of some TGP by using the data tables from the mainboard. You'll need these table roms in Model2.zip or inside the game zip. Thanks to Peabo for the donation of a Daytona board that helped to understand how they worked. This has fixed most of the bugs in daytona usa (reverse and most invisble wall hits) and sega rally (automatic transmission).

 

- Improved color table decoding that gives more bright colors for some games.

 

- Improved SCSP timing. It should be more accurate and musics should not sound out of sync anymore. As a bonus feature I've left in a debug sound player that allows you to load a SSF (Saturn Sound Format) file for playing. To use it, load a game using SCSP (model 2a,b or c) and enter test mode (so it doesn't send sound commands) then press LeftControl+F5 and choose the ssf file to play.

 

- Improved clipping. By moving to vertex/pixel shaders I've got rid of all the clipping issues that happened with ATI video cards and recent NVIDIA ones. Remember to remove set SoftwareVertexProcessing to 0. You'll need a pixel shader 1.1 and vertex shader 1.1 capable card. It's the lowest shader version so any video should work. Asa side effect of this change, there is only a geometrizer now, so the Geometrizer option in the ini file is not used.

 

- Fixed problems with textures ending in the lowest line of the texture sheet not being uploaded to direct3d (sega rally black background in 2nd stage and topskater missing floors).

 

- Added Wave Runner (Model 2C)

 

- Added support for direct3d automimpap generation (see emulator.ini AutoMip option)

 

- Added network emulation (see NETWORK section below)
