Has anyone tried the tohkbd in android console emulators ?

I tried several and all of them have the problem that you can't hold a key especially the up/down/left/right keys. so games are unplayable. for example in jumpnruns you can't run. is there any workaround for that problem? i use sailfish os 1.1.7.25 and tohkbd software 0.41.

last but not least:
Thank you Dirk Kimmo and Andrew for this great piece of Hardware which makes my Jolla complete ! I tried it for a month now use it daily for messaging and really get used to it. Only things missing are qwertz layout support in sailfishos and gaming capabilities if the problem mentioned above is fixed.
