I tried the hacks, they didn't really work well and were super unstable. For the script, are you talking about one that takes VX Ace to MV/MZ? I've already done most of that now, I did run a script early on but it merely moved maps/events/database, etc. You still were left with doing all the work to migrate plugins to JS, upscale artwork appropriately, fix eventing that was broken between versions. The script was helpful, although I ended up just redoing all the maps to the new tilesets since they looked nicer and it was a bit jarring having some in new tilesets and others in old.
