Thanks for the response. Might you be able to share any partner channels that see a lot of cheermote activity so we can idle in the hopes of seeing one?
Failing that, an example of what a cheermote IRC message with tags looks like would be a good start. Would it be the same as a regular cheer but just with different text? e.g.
@bits=100 :twitch_username!twitch_username@twitch_username.tmi.twitch.tv PRIVMSG #channel :Kappa100
