Acid-burn

Hi all. This month I have acquired what I think is a pandora box 7 3d, but I'm not sure. The one I bought is this link: https://www.amazon.es/gp/product/B07F1LNYJT/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 and I have taken a picture of your plate in case someone is able to identify the chip. I'm having trouble integrating dreamcast games. I only manage to load games of psp, psx and n64. For how many more systems is compatible? Thank you
