TRX64 Alternative Firmware Emerges for Ultimate 64

A new project called TRX64 has appeared offering alternative firmware for the Ultimate 64 Elite II and C64 Ultimate. The work is still in its early stages, but demonstrates the hardware's capability to run systems beyond the Commodore 64 it was designed for, since the Ultimate 64 is built around an FPGA. The Ultimate 64 is a modern FPGA-based recreation of the C64 developed to run original hardware and software at full speed without emulation.
