Hello, I've been a Swap Magic/flip top user for quite awhile now, and I'm posting in the case of my friend's predicament. Recently I suggested that he purchase the Swap Magic discs with flip top case. He obtained two PS2s as well. The model numbers of the PS2s are: SCPH-39001 SCPH-30001 R For some odd reason, he cannot get any backups to boot up properly. They skip badly or do not load at all. Despite switching modes, PAL games still flicker. He also cannot get any ELFs to boot up off a USB flash drive. He has HD Loader as well, and a few games, but not all, will work on it. Original games run flawlessly, as well as homebrew programs that boot from disc. He has tried booting all these things on both PS2s, with similar results. Some discs that he had a small quantity of booted and ran the backups flawlessly, they were: Verbatim DataLifePlus DVD+R, and Maxell DVD+R. Other discs that did not work, despite their high quality were: HP DVD-R, Memorex DVD-R, and oddly enough, some Verbatim DVD+R that, unlike the Verbatim that booted [2.4x max speed] were 16x max speed instead. Also, if it is pertinent information, the slower max speed Verbatims had the following number on the disc: ZD5191-DVR-T47D, while the higher max speed Verbatims had the following number on the disc: ZB9638-DVR-V47. However, there is still the issue of things like PAL games, ELF files from USB, and quite a selection of games not working as they should. He has tryed cleaning the laser lens, but ended up with similar outcomes. Is there any possible explanation for this?
