Some of the Jaguar or PC Engine people may already know of my website.
But I have recently added a far more universal service:
Cartridge battery replacement and refurbishment for ANY system.
I am based in the UK but will provide the service globally.
If you are interested, my website is www.tennokoe.co.uk
Thanks for looking!
P.S. *hat in hand* I have no online presence beyond Atariage and my website and YouTube channel, so if folks with social media skillz could spread the word, I'd be grateful
