I may be wrong, but it looks to me that POKE 65344,1 pages in the cartridge memory and POKE 65344,0 restores the original memory area. Am tempted to agree, so that's &FF40 (for readability), and presumably just switches between the 16K ROM and RAM. The issue 2 board has 6K (but can take upto 16K) w...

Do we know how the RAM is accessed? And is there a ROM dump of this French version?

Looks like someone has now implemented this, see https://github.com/mamedev/mame/commit/ ... 7c6bbc1e55
