I tested this 5.3 and I have to say it's not really much of an advance. The text is all in Spanish (or Portugese?), and cannot be changed. It crashes or hangs occasionally. Ghostlop doesn't work (works only in 4.. Diggerman doesn't work (never has in NRX). The new games aren't that "new", they just weren't in the main list before. And a rather annoying bug, I've set the volume to full in the settings (it gets remembered), but it is ignored, you start a game and it's at 80% volume, I need to press 6 twice to get to 100%. Then restart NRX and it's back to 80% - even though the audio menu says its 100%. About the .ini file, I just clicked the middle button (DETECT), and it brought my games in just fine. No need for messy manual updating. I'm at a loss to understand your problem. KOF2003 appears in the main list and works but no transparencies. The only games that appear at the bottom are: Chaos demo (works) Lost Temple of RA (works) kof2004hero (doesn't work)
