I am useing Neo power kit 2.2 SL3,it runs best but if I can find the right usb spot I can get XGpro and Neomax to burn without locking up,Neomax seems bugy for me some things NKP and XG run fine have troubles on NM.
As for the USB ports I try ALL of them it seems to hate Motherboard USB the most but I have a few mobos to paly with *L* but I still have to play with it on the USB port change cords try the hub to get it to work without locking up.
NM also cant keep some SMS saves prehaps my loader is fickle enough add neomaxs basic writeing abilty and you get fickleness desu *L* no bad
SOft reset is start,select,L,R and this works for both Neomax and XG ,NPK dosent have a SMS program so the games either save or overwrite eachothers save if they save.
Going to test XG pro 1.0 6 again to make sure it was keeping stuff,haveing to softreset and save the SMS is not to bad least I know it keeps it and with doing it that way I can run multi roms without the worry of it writeing over another games save,at least for games that are Sram flash seems to save regardless.
