Here is REICAST, a Dreamcast emulator.

preview1.png
This version is for now Alpha version. So expect Crashes!

Also, there is no GUI for now, so I just used some simple zenity dialog to choose gdrom file image.
You will need BIOS file for this to start (2 files, dc_bios.bin, 2Mo and dc_flash.bin 128ko).
For the VMU, 2 blank VMU will be created at 1st start. Go to BIOS to format them (to launch BIOS, cancel the zenity file picker dialog).
A wiki is open here, please update with your results: http://pandorawiki.org/Reicast_Compatibility_List

Sources can be found here: https://github.com/reicast/reicast-emulator

In-game key:
  • Use "f" to switch frameskip off/1/2/3 (off by default)
  • Use "s" to switch sound (on by default)
  • Use "w" to swap dpad / left nub function
  • Use "a" to switch left nub accuracy from accurate / fast (accurate by default)
  • Use "c" to show/hide Performance info (default to hide).
Still no OSD for now


/!\
This Software put lots of pressure on the CPU and GPU.
You will have crash on high Overclock
GPU Driver is a sentivite mater here.
For Gigahertz model, use at least v4.03.002 version
For Rebirth model, use 4.03.002 or a 4.04
For CC, use 4.04 or 4.00
/!\

Is there a pnd or firmware to update the gpu driver rather than having to use command line prompts
 
That is command line not just an update dont like dipping into the unknown
 
I know it's still early, but is there a way for RIECAST to automatically switch to the proper regional bios for games?  I have mixed bag of Pal, US, and Jap games for my modded Dreamcast in the early days.  It is a pain now in RIECAST to manually copy a replace correct region bios.
 
I have come to the conclusion if you have a cc pandora this is a waste of time tried updating 4.00 is the default and struggles to render 1/4 of the screen at very low framerate 4.04 and 4.03 garbles up the text to green characters and renders the screen at low framerate with blackened graphics tested soul calibur on cc pandora oc to 1ghz
 
On the 1 Ghz the 4.03 GPU/SGX driver seems faster but it does not do the lighting effects correctly. In Skies of Arcadia many of the visual lighting effects (lens flare, flashy magic, etc.) don't show up or are incorrect when using the 4.03 driver.

I use 4.10.00.01 found here:

I've prepared another installer with 4.10.00.01 driver a while ago, but didn't have a chance to properly test it. Instead of waiting forever I though maybe better I'll just post it:

http://notaz.gp2x.de/misc/pnd/sgx_drivers_r2.pnd

Note that you need to have SuperZaxxon 1.60rc or newer installed to use 4.10.00.01.

I have an issue to report regarding it. Which is that its not saving the date and time after inputting it.

indeed. It's an issue with the PND, Fat32 write access I guess... I'll look into that.

*EDIT* I think it works, but I'm not sure it likes 2013 dates... I have to dig...

@Zero3K: I don't see anything out of the ordinary in the log. Try setting a date in 1998-2002 range to see if it works?
