those "survey" things are (i think) allways fake. just to make money people create these. even surveys that are "free" will not work. i tried some time ago for myself (on other things i wanted to download). even those "free" surveys where you have register on some other website (like amazon, etc) for advertised products or some other crap do not work. and those 360/ps3 emulators will not work on pc, because emulators allways need more performance than the system, you want to emulate, has by itself. for example: if you emulate ps2 or n64 it will take much pc performance, 20% ~ 80% more than ps2/n64 had by itself (only guessing those numbers). another problem is that in most cases its impossible to emulate the hardware to 100%, only similar hardware parts in your pc would be able to emulate to 100%. with similar hardware parts i mean that there a the same chips on the pcb/circuit board, but are made from different manufacturers. for emaple: some avm fritzbox routers had same components as speedport routers. ~> possible to make speedport router to be a avm fritzbox router, but even then there are still some problems in cause of functionality/performance. with all that in mind i would say that even modern high-end-pc would have trouble emulating 360/ps3. even the 360 has already x64 3-core-cpu (a 3,2 ghz), 512mb ddr3 ram (700 mhz) and custom ati gpu. could write more now, but i think its enough for now. edit: why not take the "bios" from a jtag/rgh 360? those 360 consoles use modified system software/kernel and are based on the original system software/kernel. people use programs to decrypt those files and modify them before flashing those on a 360, there you should get a "bios". and besides... they are usually not called "bios" (i know because i flashed my 360 myself). ~> another hint that those files you wanted to download are fake.
