Saturnin WIP News

Runik posted this news concerning his Sega Saturn emulator for Windows:

At least ! After months of work, my cache is finally up and working ! I spent the last weeks trying to understand why some pages weren't properly reloaded. After adding a cell viewer to the debugger, it dawned on me that I wasn't detecting any color ram change, hence the cache trouble I was experiencing ...

Now everything works fine, and I can move on something else. I will come back to it later, as there's a lot of room for improvement, but currently I need to work on something else for a change

What's next :
- understanding why the cdblock gets full while playing some videos, and doesn't clears itself
- start working on the DSP, as it's used in quite a lot of games
- adding the rotating backgrounds (yeah, some mode vdp2 :/)
- adding the line / cell scroll (used by some Capcom games)

I also have to understand why some games (like Radiant Silvergun or Metal Slug) run that slow ingame ... it's not a display problem, as when it's disabled the speed stays the same, but it's annoying.

Well, that's all for now
