Release notes:
There is not so much visible changes for more than year of work, but much more internal changes, overall compatibility and graphics quality.
First of all, the new SH4 core now have full MMU support for interpreter/dynarec modes, which is slightly improved compatibility and allow to run most of the WinCE games fast enough to play.
Second significant change is that GPU subsystem now migrated to the DX11 interface (currently DX10-capable GPU is enough). From this version old DX9 GPU plugins (DXv3 and DXLegacy) are obsolete, although they are still supported and included in current package. Further development of the DX9 plugins is stopped for now.
And finally overall interface and usability changes. Emulator is now support 7zip romsets for the bioses and arcade systems, most of the protection/encryption formats for the arcade systems, many many new romsets added during last year and many previously unsupported games or game controllers now are supported.
Demul Dc.zip Unable
The rest is the sound subsystem have some bug fixes, improving known problems. And yes, totally forgot about... ;) Now we have our proprietary netplay plugin, too new to work fine, and totally untested, so you are welcome to try.
No, model 3 emulation still in the same state (except some overall graphics and compatibility improvements, made previously) all work currently suspended in favor to much more active supermodel emulator. Keep up good work, Bart! ;)
Not much work was done on the Naomi 2 subsystem too, there is no significant changes, just a little bit of fixes. DX11 support for Naomi 2 still imperfect and have some known issues, don't bother with that.

Demul Dc Bios Download
New GDR plugin gdrCHD. It supports Comressed Hunk of Data format (great thanks to MAME project). '.GDI' images can be converted to CHD with 'chdman' tool from MAME project (e.g. 'chdman -createcd my.gdi my.chd'). This conversion will add some redundant sectors between image tracks so it`s better to write your own '.TOC' description and feed it to 'chdman' utility. Both methods will produce functional images the difference is only in size (quick '.gdi' to '.chd' conversion is a bit larger than handmade '.toc' to '.chd').
Not implemented & bugs (TODO list):
- render to texture (we already know how to implement it. but still fights with FBO on ATI cards. if we loss battle with FBO then we will switch to pBuffer technique)
- render framebuffer
- wrong texture filter in shader (noticable in Ikaruga. we investigate this issue)
- multisampling
And now for something completely different: DEmul WIP. There are so many changes compared to previous release so let`s describe only key points: - alpha naomi support
- better compatibility
To resolve run/tune/'where-is-bios' problems - open FAQ link.
Better late than never! ;) By numerous requests we have added support of old gamepads, which don't support Event Notification, to the PAD plugin. We hope that all PADs can now be used with our emulator. Of course, not a big change for 'long-awaited' new build, but this is better than nothing. ;)
To install, just replace default padDemul with new one.
Besides compatibility status and game screenshots please report information about game's region (PAL, NTSC/JAP, NTSC/USA), size and checksum (e.g. MD5) of file 1ST_READ.BIN from the disc (or checksums of all files from the root directory), and also, if release group name is known, an nfo or full release name for further search. This will help us make up the compatibility list and search for mistakes.
Hello from Russia! We are very proud to introduce you new DC emulator DEmul! We have been trying to write new emulator that will be able to run commercial games since first and only real DC emulator Chankast so far is stopped to develop.
Emulator was started to development early in 2004 year by Wind, but just canceled after Chankast released. About half a year it has been in hibernating, but Chanka was still imperfect and emu was continued to developing. About a year it takes before it shows up BIOS spiral, then early in 2006 year Wind found some emu-russia members and run his first most desired commercial game Resident Evil: Code Veronica. Next progress was very fast and last six of seven month took improvements and debugging.
Now emulator is able to run most commercial releases by various groups all along with homebrew demos and free software. We hope you enjoyed it.
Emulator still imperfect and incomplete. A lot of work still needed. Sound, timing and graphics need improvement and speed up. Since main developer is going to be little busy to do something with DEmul next year, we do not promise fast promoting and emulation progress. We try our best to fix as many bugs as we can and improve emulation.
Compatibility list with advanced features will be later all along with plugins SDK, docs and faqs. Anyway, you can ask your questions (not dumb, please;)) by e-mail, report about some bugs or progress, please, read README.TXT file before. If you interest in development, we will glad to see you on IRC channels or forums that will be available later too. ;)
