Cool - I've got Galaxian3 PAL version with english dialogue and JPN version, I have to admit to prefer the PAL version although the JPN version is more authentic I guess. Im playing it on my PSX too with 42" Plasma and full blown 5.1 experience with REL subwoofer. Im lucky enough to have bought a PSX Analogue stick back then and still have it!
I have just got my pride and joy, a Starblade cab (Yellow Seat version). It needs a little work but I am going to restore it no expense spared.
Now my plan is to find another Starblade cab, I would prefer non-yellow seat version this time though, my plan is to turn it into a Galaxian3 cab. Thanks to the work done by Bruno we should have Galaxian3 emulated soon.
Although the PSX version is great, its just a shame that it is by todays standards quite low resolution. The emulated version will look so much better.
