- It seems like flashroms in the 16bit slot like the 29L3211 were accidentally programmed byte swapped up until now and only the 8bit slot worked correctly. - You can now program files smaller than the flashrom's size without getting a verification error - Added the special 29F1601 flashrom taken out of the Nintendo Power SF Memory carts
