New Version Of The Dreamcast Emulator Demul

October 7, 2008 by Hawq

Another WIP release for this excellent Dreamcast and Naomi emulator for Windows has appeared so let’s see what’s been done to it, post translation that is (thanks for the translation go to emu-france):

Changes:

added new GPU plugin - gpuOGlv3 (it´s recommended to install newest drivers to use this plugin, especially for ATi video cards).

What it can do:

nice sorting (still not perfect);

correct blending and shading;

emulate fog;

change video resolutions;

make .png and .jpg screenshots;

build mipmap textures;

What it can´t do (yet):

render-to-texture (we are working on it);

frame buffer rendering;

texture filtering (Ikaruga);

multisampling;

Fixed bugs in other plugins:

polygon cache bugs;

texture cache bugs;

polygon transfer trough TA with intensity mode 1 and 2 (Trigger Heart Exelica);

invisible polygon cut;

removed unneeded GPU calls;

added bugs:

who knows?

added new GDR plugin - gdrCHD. It supports MAME´s CHD images. Builtin GDI->CHD converter is still not perfect. It makes CHD images with unnecessary information but emulateable anyway. It´s recommended to use MAME´s chdman utility instead of it.

CD-ROM reading speed is now syncronized with CPU and limited to 1Mb/sec (fixes Resident Evil - Code Veronica, thanks to drkIIRaziel);

fixed old bug with invisible shots in Ikaruga´s second stage (thanks again drkIIRaziel);

added current NAOMI romsets from MAME, removed old ones;M

fixed old bugs in dynarec and code invalidation, counters and some other things;

fixed almost all memory leaks.
