Is updating framedisp really harder than rollback caster?
Or is it just the fact that you're going to have to do more than one thing once the game's released?
it's more about quantity than anything else yeah.
i give absolutely no guarantees on rollback anything, that's a longterm anything
if i decide to go for it. i gave a big fat maybe on that for a reason. you don't even know how much work it'd be and i don't know how much time i'd be able or willing to give to it then. for all i know i'll play it and decide i hate the game and my rage will be the kind of thing heard for ages.
iamp's took two months to go from "i have a plan" to "it works 95% of the time", and a few more months before it hit 99%. i don't think anything else would go faster. you can read about it over at
an article i wrote on mizuumi. it still has a few bugs, like uncommon desyncs (mostly yuyuko/patchouli related in my experience) and spectator desyncs(the players are still fine, but the specs desync. no clue on this one.). there's not enough of a player base to make fixing them worth my while.
also, bear in mind that amp is probably the simplest of the doujin fighters available, the coding is very plain. more elaborate things would take more effort.
