Welcome to the scene Andy
Yes you do need a dump of the firmware, just wait until your GP32 arrives and then make the dump.
You can also use a custom firmware from here: http://www.gp32x.de/cgi-bin/cfiles.cgi?0,0,0,0,42
Beware though, that Geepee is only used for testing stuff and taking screenshots, it's not pretty optimized in terms of speed!
if you cant wait then i am sure that there is someone out there who has decided to leave their bios lying around on the web,, if someone posts the filename of it then you should be able to find it,, or i think you could use a free bios/fw like most have on their gps,,
anyhow welcome,, welcome,, btw did you get a blu or flu???
flus rules,,,
blu is far better, dont get confused
Do most people flash their firmware to a non standard release? I got the 166mhz blu. Should I have gotten a Flu?? I thught Blu was latest + greatest hehe. What would be really cool is if we could get a 266mhz hehe.
Don't count on getting over 188Mhz though, BLU's have a lower success rate at overclocking.
