i need Artemis and rebug cex 4.84 seems to be not compatible with it. a friend has overflow and it works on it. is it safe to update using usb from rebug 4.84.2 rex cobra 8.1 to overflow v5 cex 4.84 cobra 7.55??? i am afraid it won't works since overflow has cobra 7.55 and rebug has 8.1. and multiman will work again?i have to reinstall it? what about installed psn games already installed?do i have to reinstall them again? rebug is ok although using retroarch it did made my ps3 slim freeze a few times and i had to reset it.other than that,rebug works great.
