instead of green. But, the listed checksums on the screen match the
checksums printed on the ROM labels... this seems wierd to me.
However, this has been verified to happen on a real PCB
+
+ There was a PCB on eBay that used mask roms for the program roms with the following CRC16 values:
+
+ U110 050C
+ u111 F343
+ U112 201D
+ U113 FB4x (x maybe 0, 6 or 8. The picture wasn't clear for this last number)
+
+ These are different then the current set and might have the checksum test corrected.
