Dream in the Dark DEMO v0.9-preview

Dream in the Dark for Sega Dreamcast. The release is a CDI which can be burned to CD-ROM for play on a real Sega Dreamcast or played via Emulation with Flycast/nullDC/etc. This build contains the demo datasets of Alone in the Dark 1, Alone in the Dark 2, and Jack in the Dark. The CDI was trimmed down - if the full ~700MB CDI is desired we can release that as well.

Please refer to the release thread on DCEmulation for more information.

KNOWN ENGINE BUGS:

Renderer: RGL subsystem with AITD2+ may miscalculate Occlusion/Masks in complicated scenes. This is more a limitation of GLdc and PVR's transparency sorting than Dream in the Dark, but it will be improved over development of the port.

Save/Load: VMU for a single SAVE takes up 50 blocks. This will be tweaked/compressed over time.

Save/Load: Largely unsupported for these Demo versions. While it works fine with the retail releases, the DEMO versions technically do not support saving or loading themselves, so it may spit undefined behavior. Since the Demos are short, there should be no reason to use the Save/Load feature.

KNOWN GAME BUGS:

AITD2 Demo: The Pause screen has pink text - the Demo of AITD2 is formatted very differently and I didn't have time to tweak it, however, the other text colors are correct.

JACK: Save/Load works but may produce issues.
