Is it possible to just display the bosses (and their tails) hp bar?
Unless there is a reason to not filter non-bosses hp, non-bosses hp are just clutters.
Btw, there are indeed stutters every 2 second at the beginning, but resolved for the rest of the game after going into a quest.
US Old 3ds, MHXX v1.1, translation patch 2.1 (layeredfs.plg method).
Anyway, nice work on this plugin! Thank you for doing this!
Yes, that's planned for a future update. Currently pretty low priority however.
As for the stuttering, I had suspected that old3DS machines might run into problems.
The plugin does some aggressive memory searching in order to locate the main pointer to the monster structures; however, it's not going to find it until you enter the first quest after a game reboot.
As soon as you do that, it saves the pointer and stops searching, which explains why the stuttering disappears.
A similar effect occurs on the New3DS, except it's just a generic drop in framerate; I implemented a counter-measure to ensure that it runs smoothly on New3DSs, but apparently that wasn't enough for the older hardware.
Try this build, see if it changes anything.
