Viper Phase 1

Does anyone know if it's possible to "upgrade" a Japanese VP1 to VP1 New Version?

It looks like they use socketed eproms on the cartridge so it's probably not too difficult. I have no idea though.

You won't have to do a byte swap like you would for changing regions. I'm not sure if you would have to burn a full set or just a couple though.

If I had one I would test it but alas I do not.

Hmm, I suppose taking a look at at the MAME dumps would give a hint. Should have thought of that A ROM swap (partial or full) sounds a-ok Been looking for VP1 New for a while and possibly found a decently priced VP1 Old. Just wanted to make sure it wasn't an absolute no-no before I pick it up.

Thanks for the input guys

Let us know if you try it out.
