Hi guys,

I'm joining the team, to exchange some ideas and findings about FM Towns and PC emulation on Amiga 😀

On FM Towns to turn Fastmode on, all we need is set the lower bit of I/O port 0x05ec to 1.

mov dx,0x05ec
mov al,1
out dx,al

Compile in nasm with usual boilerplate, and voila enjoy faster mem access 😀

Just set it back to 0, to turn it off. The Fast led will turn on/off accordingly.

Hope this helps!
