What is an FPGA and why is it important for the C64 Ultimate?

An FPGA (Field-Programmable Gate Array) is a type of integrated circuit that can be programmed after manufacturing. In the C64 Ultimate, it emulates the original hardware of the Commodore 64, allowing it to run classic software. Its programmability makes it ideal for running different computer cores, enhancing the retro experience.

Will this decision affect other retro computing hardware?

While this specific incident involved Commodore, it sets a precedent. If companies see strong community engagement and a willingness to compromise on firmware control, it could encourage similar flexibility across the retro computing market. Conversely, if issues arise from this freedom, it might lead others to reconsider.

Can I still get my Commodore 64 Ultimate repaired if I mod it?

Commodore has stated they will not provide free support, warranty service, or replacements for units bricked or damaged by community-installed firmware or modifications. While the machine itself might still be repairable, any damage incurred due to your mods will likely be at your own expense.
