Re: Sandy SuperQBoard firmware.

Hi all!

Are there any differences between 1.16 and 1.19 firmware versions for the Sandy Super Q Board ? An update form 1.16 to 1.19 firmware will be ok?

Re: JS ROM creation

About the spreadsheet, what is the difference between the ' Chip ' and ' PCB ' colums? If i burn and use two 27(C)256, for the 0000 and 8000 parts of firmware, the same moding is needed?
