The recommended write strategy using omnipatcher is TYG02. But I tested both 8x and 4x burn and 4x seems to have less errors. I do not mind the extra wait time.
Should I change revert the write strategy back to TYG01 since I'm only at 4x?
thanks for the replies.
ps. i got a 1693s with KS09 firmware (patched with recommended omnipatcher changes).
