I recently purchased this as a set. I'm selling it because the board alone is useless to me. 【Condition】 I ran it once to check its operation. I haven't checked its operation since then. This product does not include a ROM. Please prepare one yourself. To reduce shipping costs, the heat sink has been removed. Please install it yourself. It will be shipped via Yu-Packet Post. Also, if you would like a ROM included, please comment before purchasing and I will include it. (The product price will change.) Please consider this as junk and no returns or refunds will be accepted.
