1.0 - Installation
First off, start by burning the Stardust.iso file to a CD. I use NERO or cdrecord to do this. Burn it as a standard ISO disc-at-once with finalisation enabled. This should work, if it doesnt - try track-at-once and/or a lower speed.
There are now more methods of installation, the first of which is done by using Cromwell. Inside this archive you should have received a file named "800x600.bin" and one named "640x480.bin" (both in /Stardust BIOS/ - Obviously if one doesnt work, use the other, start with 640x480.bin).
To use this method you will need to either flash your modchip, or TSOP with either file (though the installer has been optimised for 640x480). I'll let you decide how to flash. It only requires a 256K bank but you may double it up to take up 512K or even a full 1MB.
