Just keep in mind to have at least 7 t-states between every transfer

MSX-turboR and 7MHz have automatic slowdowns implemented to that works
too.
No, this is not completely true!!

I have to write a gfx data burst to VRAM as quickly as possible while the
display, and possibly sprites are enabled.
I've noticed data corruption when using quick transfer loops (via POP)

disappears when display is disabled.
Is there an accurate way to determine required VDP timings
