Big iFlash2PS2 breakthrough! @rezenclowd3 informed me that he and pcm720 had tried following the advice of @Gusse__ to add 100pf capacitors to ground on the RESET, DIOW, DIOR and DMACK pads of the PS2 motherboard. They found that with this modification in place the iFlash was much more reliable at detecting SD cards even when the PS2 was hot, which has been a problem with some PS2s (especially SCPH-70001 models). After some of my own tinkering I found that 200pf capacitors seem to work better for GH-032 motherboards, making hot reboots basically 100% reliable. I don't see any negative effects on GH-035 motherboards from using 200pf capacitors, so I'm going to recommend that as standard for all PS2s. Now for the big news. Not only does this mod improve hot restart reliability, it also has unlocked reliable detection of many previously incompatible SD cards including SanDisk 1TB and 1.5TB cards! There are probably many other previously incompatible cards that will work now, but I don't have a huge sample size to test at the moment. I've updated the install guide on my website to explain how to perform the mod. It works on all revisions of the iFlash flex. arthrimus.com/support/iflash… I've ordered a reel of 200pf capacitors and once they arrive next week I will begin including them with each iFlash kit sold.
