When I went to Linker4U.com and ModChipStore.com, they both had different compatibilites for the Swap Magic. One said it only works V4-V7, and one said that it works for all of them except for V9-V10. Can someone tell me the real compatibilities? I would like to know if it will work for V9 and V10. Also, does the V9/SCPH-5000X Flip Top (10 screws I think...) work for V10 of the PS2? Lastly, I am going to return my V7 PS2 for a V9 or a V10 PS2. Is that a good decision? Which should I try to get... V9 or V10? Why?
