Please add me to the interest list. Thank you.

I'll wait for your final outcome before getting the VG460 board as a donor or I'll get VG420 board instead if I find one.

Hammy, I re-programmed the chip with the same data but left "Protect after programming" unchecked. All games are working now. Thank you so much

I re-burned the 3 rom files but it was the same. I'm using 27c322 for all files. Is the 28c256 chip located at the position I circled on picture? Is the chip supposed to be empty? I never programmed 28c256. To erase the chip in unprotected mode, do I uncheck 2 checkboxes under Others and...
