i wanted to drop a quick note and thank the couple people that posted the "review" explaining how to upgrade your SP-90 [even though it supposedly isnt upgradable]. i was very excited to find out that i had pretty much bought an sp100, minus the backlite and remote [that aint too important!]. the only thing i need to add is that when you open the file in the hex editor and change imp-100 to sp-90, you also need to add two periods [..] after the sp-90 to compensate for the two less letters/digits in the name. maybe its obvious to most, but i didnt think of that the first time. anyway, thats about it. thanks to yall who informed us of this trick, its well appreciated! and if you discover anything else, post another review because ill be stopping in once in a while from now on.
