Not using 057 because it runs so slowly the basic DC no-disk-startup screen is stuttering along at half or three quarters speed.., but when I tried it the same thing was happening anyway.
Basically, the problem is that when I try to set an image to play under Config > GD-ROM, the only file type it wants to see is .chd and if I tell it to look at all files and pick the .cdi anyway, it tells me to "Please insert game disc."
According to the answers from a page or so back in the topic list, it's SUPPOSED to be fine with .cdi files as of 055, did that change? Am I somehow missing something? There doesn't seem to be anything else to adjust...
Edit To Add: in case it matters, my system is Win7 on a 2.1 GHz Athlon II M320, gfx is ATI Mobility Radeon HD 4200 (yeah, it's a laptop, tut tut - speed is not presently the issue.)
