I checked out your website: Your collection is simply breathtaking!
You must know lot about gaming hardware. I always find console hardware for the French market exciting. The reason is the issues with SECAM video and therefore greater chance of finding a system with eigther RGB output, i.e. the French Amiga CD32, or that can modded for RGB output, i.e. the NUS-001(FRA) models of the N64.
Are there any other console versions for the French market that one should be aware of?
