Well, since I fixed the numbers thing when I made the Lanettes PC version, I figured I might as well go and apply what I'd learned to the old-school one.
To use it, you'll need Rainmeter installed. Unzip the file to your Skins folder, and install the "PKMN RB" font that's in there. Restart Rainmeter and add the meters you want and you're done.
HP numbers now change.
All the text on the meters is now stored in the INI, rather than being part of the image, so you can change that around if you like.
Battery status now shows "Charging" when on AC power.
Meters for up to 4 cores now available.
