Depends what you mean by failed
Astrocade has a pretty good number of above average games, it sold well but only for 2 years or so
MegaDuck no but it was probably capable of it
Pokemon mini, I assume no but capable of it
GX4000 not included because its a computer in a different case so it had many good games
Hanimex Soundic, just typical pong games but probably sold a lot for the time

it has hundreds of games, I consider a failed system something that lasts a couple of months and then they send back the unsold stock
