Matt Ownby the DAPHNE Developer/Project Coordinator of the Daphne Emulator has updated the news surrounding his Port to GP2X progress, heres the info:
18 Jan 06 - Good news! I got some of the hacker samples that have been released to compile and work properly using a different compiler. My previous attempt at this had failed, which was putting a serious roadblock in my way. RGB scaling is working. YUV scaling works in theory but I have not yet seen this working in action, and this is something we will need in order to get fixed resolution games like Super Don working.
