The Z80 turbo is almost complete Smile Thanks to some tips from grauw I managed to adapt the SFX player in such a way that the frequency gets correctly compensated for turbo CPU's. This little trick will propably only work well on panasonic turbo enable MSX2+ machines but we could try the 7Mhz turbo machines out there as well.

From this stage on all the MSX2 and higher machines are fully supported, this side project however is starting to take too much time so it stops from here. We now are going to focus on the map building as soon as the new gfx tiles are available. In the mean time I finish the joypad support.

Ah, you shift the frequency table? Glad to hear that you tried it, ’cause I was also planning to use it in Synthesix Smile. It should work on 7MHz circuits which insert wait states, but not on those which throttle the clock frequency (probably the majority, though I think it’s easy to adapt them, given that I recall doing that once in the 8250 we used to have).

Nice to hear an update Smile.

No I simply multiplied the frequency value that is read from the data by 1,5 (divide by two then add to the originial value) and it works Smile

Allright work is done. Smile 2 questions:

1: can sombody test thisrom on a 7Mhz MSX2? boot with key 2 pressed to enable the turbo compensation mechanisms. I need to know how the screensplit looks like and how it sounds.
2: How can I detect the presence of a joystick?

The ROM enables panasonic turbo, on openmsx I get vram scrambeling. Does the wait feature work on panasonic?

I have no clue. But indeed on openmsx I see the same scrambling. not on bluemsx and on the real machine it runs excellent.

Oh then openmsx is missing the wait pin simulation.
On bluemsx is no scrambeling because vram scrambeling simulation is new.
