G&W Octopus has now been dumped smile Thanks to everyone involved!

The game is SM5A based and it's the oldest G&W game emulated by MAME so far. There are now three different SM5A games running without problems in MAME (Mickey Mouse, Fire and Octopus) so the MCU emulation seems be good. I'm currently working on some other wide screen series games (Turtle Bridge and Fire Attack) but they both are SM510 based.
