Tomy Upgrades


Recommended Posts

I put an F18A in mine. 

And then replaced the powersupply with a PicoPSU. 

 

Not many of the PicoPSU's provide -5v, and after changing to the F18A, the only place -5v went was the cartridge port. So I didn't care if it was not available.

 

At that point, I think the sound chip gets it's clock from the F18A, and the crystal for the 9995 could be upgrade from 10.whatever to 12Mhz. But I haven't tried that yet.

 

It would be interesting to try forcing it to zero wait states too.
