@zing Thanks! I will trie it.

Ok I think I can try it with

bluemsx_vdp_synctype

But what is the option for the fMSX?

And where in my recalbox installation must I change this?

Hello, i have searched for a solution but cannot find it.
I really love recalbox 2.7.7 on my Pi. Lots of platforms run very good but ween I play good old MSX games they go a bit too fast. Faster than normal MSX. So I cannot break my records anymore or am I too slow ?

Anyway is there a setting where I can change this?
I must affect only my MSX…

Thanks in advance for your help!
