Can someone help me make a Habbo Retro RP

[Jaden]

If only that would ever be released :L (Roleplay edition) the kid is asking for an already made emulator, not a base btw. If we are talking base wise I'll base it on the IDK Project or even Sierra if anything

I wrote my own Gradle Java Emulator, and I think Mango is fairly better than Seirra and IDK (Even though they're decent emulators).
And my MangoRP is finished.
