TThere are multiple gameplay breaking bugs with the Brook Retro Board that I detail in these two threads:
What is a real concern is how easy it is to notice these bugs… they are not edge cases, they make the product unusable. Worse, the button press dropping bug has been known for a year, and yet no firmware update has been released. Even worse, after spending a couple weeks trying to get customer service from Brook, they told me to reach out to the retailer that I bought the board from: Arcade Shock. After exchanging emails back and forth with Arcade Shock, they were clear that there is no firmware update release date for fixing these issues. In fact, no firmware update of any kind has ever been released for the Brook Retro Board.
The nail in the coffin is when I requested to return the defective product to Arcade Shock, they said that I would have to pay shipping and a 15% restocking fee.
Buyer beware! Avoid the Brook Retro Board until the product has at least the basic advertised functionality fixed with a firmware update. I am skeptical that a firmware update will ever be released to address these issues, and I have doubts now about Arcade Shock’s customer service.
