Quoted from littlecammi:Your idea for hardware looks okay, but once all that stuff goes under the playfield all people will see (and judge) of your mod will be whatever video (and still picture) files come with it. MikeD's images were great, but you won't be re-using his files. And not many people will want to buy your system if they have to supply there own video files for it.
My Creature was built in March of 1993 and I bought it in 1994. Its original hologram hasn't been exposed much since then and is still nice and green. As soon as I get a pin I try to stockpile unique spare parts for it that I think I might need in future years, so I ordered a few lagoon window plastics and a spare OEM hologram (which I have stored in a closed box still in the WMS packaging). After enjoying the original hologram for twenty years I switched over to the MikeD mod for the variety of images displayed during gameplay (instead of just seeing the Creature occasionally during multiball). If only the game could display the original hologram during multiball and MikeD's images the rest of the time... (Spare hologram is not for sale. Please do not PM me.)
Uh, PinSound worked around that problem pretty effectively ...
