I can't access Eidolons from my work, but yes that's the datasheet I (and others) used for SegaCD emulation.

There *should* be a datasheet on Eidolons-Inn that covers the CD controller IC (LC89510). It's a datasheet of a hardware compatible controller (the first 16 or so registers are the ones if interrest). I've uploaded it a long time ago and is way better then the other LC89510 sheets floating around th...

A bit more info: From debugging I can see the bottle graphics being downloaded into cram instead of vram. (this would explain the missing bottle, and the corrupt palette). Can you spot anything wrong with my code register update? This is the only function where I update it: I don't have any source ...

There are also some patents regarding Comix Zone, which describes the technique used to create the comics look. I can't find it right now, but I've seen it in the past. It's very interresting because it seems you would get the source of this game if you bought the patent. Edit: Patent number: 6010405

What about Eidolon's Inn ? As I posted in another thread, it would be nice to centralize all the technical information. However, I don't have any spare time at all this month, so I won't be able to show any initiative the coming weeks.

Ummm.....why not write completely in ASM? :P Because I have to write a different version for each platform. You can't just simply re-compile your 32-bits ASM into a 64-bits object ;) That's why I switched to C/C++ only. With some small #ifdefs and a simple recompile I can have a x86 and x64 binary ...

Sharing technical information

What about setting up a some sort of Wiki were we all can submit technical information about various Sega systems ? That would give all of us a good knowledge base without the need for ...

Intrinsic functions

Since you are not allowed to use inline ASM in the VC++ compilers for x64 platforms, I was surfing on MSDN and came acros this: http://msdn.microsoft.com/en-us/library/aa983406.aspx Has anyone actually tried this in a CPU emulator ? I wasn't aware of this intrinsic function, but this could surely sp...

You might want to look into the following DWM API calls:

DwmSetDxFrameDuration
DwmSetPresentParameters

I have not done any testing, but it seems these functions will control how the DWM updates its screen.

On a sidenote, I've been trying to add full localization support (menus, dialgos and prehaps maybe the emu messages as well). Currently the most best way to do this is to create satellite DLLs. This requires the translator to have Visual Studio compilers and follow very long steps to successfully c...

Hi Stef :D Hehe no.. I will stick to emulation dev for now, but I'm very interested to see how the homebrew genny scene is coming along. It's good to see that a lot of people still are making things for those good old consoles, that motivates me . I had that datasheet floating around for a few years...
