Ads keep us online. Without them, we wouldn't exist. We don't have
paywalls or sell mods - we never will. But every month we have large bills
and running ads is our only way to cover them. Please consider unblocking us. Thank you from GameBanana <3
I doubt it's impossible, but it definitely wouldn't be easy. This would require completely replacing the intro (or adding a custom one if it's applied to Sonic alone), plus the code for the intro itself. Ideally, it'd also include touched up graphics (i.e. using Sonic 3 Sonic and bringing the surfboard up to snuff if it needs changes).
Suffice it to say, 43 points is a bit low for the amount of work that would need to be done here, so if you (or anyone else reading this) wants this to be completed you should consider adding more points to the bounty.
