2 Comments

Last weekend, marqs released firmware v0.91 for the CPS2 Digital AV Interface. The new firmware finally has an OSD implemented and brings back the scanlines. Further features include TX mode, quad stereo output and two additional VESA resolutions (1280×1024 and 1600×1200). You can find all functions and some explanations among the OSD menu structure and the sample pictures below.

There are only some components missing that could be figured out by looking at the service manuals.

However, I couldn’t try it out back then because I didn’t have a working 470 or 490. I focused on repairing my 470 first and then adding a PAL/NTSC switch. Eventually, I bought the needed components and two broken 490s to experiment with.
