Here's a little sneaky peek at the RomWriter for 39SF040
that is coming soon. The board is for anybody that wants to upgrade or
reprogram their RomWBW ROM but doesn't have an EPROM programmer. It is
totally standalone so doesn't rely on Windows, Mac or Linux. Anything
that can put a file on an SD card will work! It has one job - writing
RomWBW ROMs. That's it. Available from December 11th for just £15
