Dreamcast GDI Compatibility List

[Zimada]

Guys, guest what?
Two weeks a go i starting read all your posts from Dragoncity, about loading speed issues of presets, about covers for folders with games, and other posts… and try "REZ" that marked as "not working at all"… And found some VERY WEIRD thing.

REZ is actual WORK on my Dreamcast from HDD!

But how, you ask me? "Simple!" )))
You need start (with no luck of course) optimized GDI image of "REZ (EU)" TREE times after you turn on power of your HDD, with strange settings in "preset" without save this settings as preset.
And in fourth time when you start the REZ with all this settings it START without any problems!

REZ (EU) - WORK! (but with weird sequences of steps!)
1st step - Start optimized GDI image of disk with this settings:
Use DMA - marked
Emulate async read - unmarked the "true" box (it's very imported!)
Fast boot - marked
Load memory - 0x8C004000
Emulate CDDA - unmarked
Save as preset - unmarked
2nd step - Repeat "1st step" 3 times! (when console is stuck just turn off your console and then turn it on again. Not turn off HDD!)
3th step - Repeat "1st step" in fourth time and VOILA! IT WORK!!!
WITH SOUND AND MUSIC, AND ALL THIS CRAZY COLORFUL VECTOR SHIT! ))))

Somebody may answer "WHY?!"
