Stumbling upon this yesterday, I grabbed the amd64 deb and slammed it on to my system. I was quite surprised to find this ran on my machine at all, but it actually ran pretty well considering.

Ubuntu Intrepid Ibex (8.10) amd64
2.2Ghz AMD Athlon 64 3500+ (single core)
8GB UMAX Pulsar Dual Channel PC2-6400 DDR2 SDRAM (strong point)
450Mhz 128MB DDR2 RAM PCI-e x16 ATI Radeon X1550 (cheap)

Of course it ran slowly and with some beautiful graphical errors (Daytona USA in rainbow-nightmare mode), but it ran. Not sure if the particular game would look better on a faster machine or not though, as this test was not scientific at all. I was greatly impressed at this happening out-of-the-box after my recent battles with PCSX2.

:Results:

Boot with empty GDRom:
Menu appears and functions well, except sounds are funny and mostly missing. Rendering is slow, but likely to be hardware related.

Boot with GDRom disc image:
The Dreamcast logo bounces into place and the sound is choppy, then the game loads and there's a lot of loud static noise for a moment.
Daytona USA loads, but features no textures or sound. Only geometries are rendered, but in so many beautiful colors! I was able to blindly navigate the menus and play the first level and not too slowly either (~70%) (~20% -x).
Unfortunately I could not steer. It seems that the controller is not supporting analogue input, although everything else on the controller works. Keyboard input for analogue works.

Boot with GDRom disc:
As yet untested. All my discs are in storage at my parents house... in the US

Note: If any of these issues are already known or already fixed in the svn, please excuse my newness. I plan to check it out tonight and try again with another game.

nkeynes,

Indeed I was surprised as well. Things of course slow down a bit when there's a wide view or a lot of objects rendered in the window. The lowest speeds I've gotten in-game are around 40%.

As for the controller, it did configure, but in-game I get no response from the analogue stick on my gamepad, which you insightfully described in great detail. In fact, the game pad is a Dual Shock 2 (sin!) plugged into an Elcom dual controller adapter. The Directional pad works in game as well as the buttons, but the left analogue stick does nothing I didn't think to try configuring the right analogue stick, but I expect the same results.

Also, I will post screenshots of Daytona later next week. My computer is in a box being shipped to my new home! *withdrawals setting in already*

I did compile the SVN by the way, which was refreshingly easy to do. I got pretty much the same results as running the amd64 deb, but a little better sound and some of the textures on Daytona's HUD appeared, but the game still has no sound at all. After compiling the SVN I tried another game, Phantasy Star Online, which also displayed relatively few textures but did not suffer from Rainbow Road Syndrome and had some sound. Unfortunately, it is not possible to log in to the original version of the game so I was not able to examine any in-game play. I'll have to look up the Schthack version sometime.[/b]
