Is there any way/server to try all new sps?

I've been out of the game for 3 years and i would like to come back. The thing is, everything has changed a lot, 4 sps were added for every job so... My questions is: is there any private server where everything is unlocked and i can try all the new sps out. Or a way I can modifiy the game on a local server?
I dont mind if i have to code my own server following a guide or whatever.
Please let me know.
Thank you all :)

U can't try all with buffs/debuffs, and the same as gameforge.nostale, but you can try in OpenNos servers like Fagtale or CelestialNos, you can register and download easy and find all the info in this forum ^^

Good luck ^^
