Bruno, please tell me you only will emulate this for keeping it safe for the future. Since your machine is running, it really deserves to be fixed in it's original form !
Of course
There is no reason to emulate something working
As far as I remember, only the laser disc players are broken, but there are a lot of specialists here and there
But emulation could be the only way to play 'Project Dragoon' mission by example (my GT-6 is loaded for playing 'Attack Of The Zolgear' only), and I'm not sure to have a complete set for 'Dragoon'
But hey, we are still very far for an *working* emulator anyway
Maybe the biggest challenge for the emulation scene ?
