X-ROM
From PHWiki
A 512 Mbit flash cart. Unlike most flash carts that use flash chips from Intel, this one has flash chips from AMD.
Compatible with Pogoshell, and supposedly all 512 Mbits can be used in the compilation, as long as no more than 256 Mbits of it are non-GBA roms. For instance, you cannot have more than 256 Mbits of NES roms, JPEGs, books, GSM audio, etc.
The X-Rom went out of stock from all major suppliers that carried it in late 2005, and as of June 2006, it has not come back into stock.
