DreamGBC is yet another Game Boy Color emulator. There isn’t an awful lot to say about this emulator. It does appear to be discontinued with no development been seen since 2005.
The objective of DreamGBC was to emulate as many GameBoy carts along with various features that improve games but weren’t on a real Game Boy Color.
The two upsides to DreamGBC is that it does seem fairly compatible and is easily configurable.
