Retro Computing: Commodore 64 Ultimate 64 48MHZ
A new amazing firmware upgrade has been released for the Ultimate 64 which enables the CPU to be over clocked from 2mhz right up to 48mhz.
I decided to install the upgrade and put it through its paces.
I'm also working on a part two where I test a few more games and GEOS.
Features Elite 128, starglider and stunt car racer and some REU tests.
