I don't think they have one for the Wifi Plaza AFAIK.
What's notable is that they actually bothered to make 8-bit remixes of areas that didn't exist in G/S/C, or had incorrect music in G/S/C due to space limitations. These areas are:
*Global Terminal
*Cerulean City (It used the Viridian/Pewter/Saffron theme in G/S/C)
*Fuschia City (It used the Celadon theme in G/S/C. Now it uses the Cerulean theme, which is how it is in R/G/B/Y/FR/LG)
*Route 24 & Route 25 (It used the generic Kanto route theme in G/S/C)
*Route 47 & 48 (Didn't exist in G/S/C)
Also there's some music choices that bother me. Here's some areas with incorrect music:
*Mt. Moon
- Theme used in R/G/B/Y: Generic cave theme
- Theme used in G/S/C: Kanto cave theme
- Theme used in FR/LG: Generic cave theme
- Theme used in HG/SS: Johto cave theme (WTF!?!?!?)
*Diglett's Cave
- Theme used in R/G/B/Y: Viridian Forest theme
- Theme used in G/S/C: Kanto cave theme
- Theme used in FR/LG: Viridian Forest theme
- Theme used in HG/SS: Kanto cave theme
*Route 2
- Theme used in R/G/B/Y: Route 1 theme
- Theme used in G/S/C: Viridian Forest theme
- Theme used in FR/LG: Route 1 theme
- Theme used in HG/SS: Generic Kanto Route theme (even though they made a remix of the Route 1 music -_-)
*Seafoam Islands
- Theme used in R/G/B/Y: Viridian Forest theme
- Theme used in G/S/C: N/A
- Theme used in FR/LG: Viridian Forest theme
- Theme used in HG/SS: Ice Cave/Dark Cave theme (BUT THEY MADE A REMIX OF THE VIRIDIAN FOREST MUSIC -_-)
*Oak's lab
- Theme used in R/G/B/Y: Oak's theme
- Theme used in G/S/C: Oak's theme
- Theme used in FR/LG: Oak's theme
- Theme used in HG/SS: Pallet Town theme (WTF!?!?!?)
I wish they corrected those... I don't really care about Cerulean Cave however, since that theme was shared with the Celadon Team Rocket hideout in R/G/B/Y/FR/LG, which no longer exists by the time G/S/C/HG/SS takes place.
