luizlizard informs us through our forums that the earlier release of XMB Theme Cycler v0.3 has a critical bug. With that, he gave us a fixed XMB Theme Cycler v0.3. He mentioned that he fixed the bug and font flashing. Another reminder from the dev - "if you ran it before flashing the fonts by yourself, please reflash 3.40 OE before flashing a theme, or in recovery mode goto Flash0 and delete "gb3s1518.bwfon..." and "jpn0.pgf...", this files where created by the bug, then run theme cycler again".
