They'll probably claim it's a port of the "ORIGINAL" Dreamcast version like they did in 2010, only to get caught out in the lie.
Better option: There's a bunch of Dreamcast mods in development for the 2004 Windows release.
- sadx-dc-lighting - restores the original palette-based lighting system from the DC version.
- sadx_dreamcast - restores models and textures from the DC version.
In addition, the mod loader itself supports ADX audio, so you can replace the WMAs from the 2004 version with the original ADXes. (Use the ADXes from the original Japanese release of SA1; around half of the tracks in the International releases were downsampled to 32 kHz due to disc space limitations.)
