Heya. If you mean developing something that uses dice instead of Pokémon showdown, not at this time unfortunately. I certainly tried when developing the system but there was just no way in my opinion to retain both the pace and mechanics of Pokémon battles without it. Other fan made systems try, and I encourage you to test those out! But they are going to be compromising on one or the other; either a very crunchy pace or different/less faithful mechanics.

at least thanks for an honest response, and i think that simplifying the mechanics doesnt hurt the system, like, i once was playing in one small camp, where dm used simplified type chart and a d6 and it was fun, it was quick, but allowed to think a bit. The only thing i do see troublesome to make is power for moves, as i still dunno how it is determined
