Thanks a lot Gerald.
As i see, here is the good bytes you have to put :
For 64kb cartridge bit 4,5,6 and 7 must be : #24,00,01,00
For 128kb cartridge bit 4,5,6 and 7 must be : #44,00,02,00
For 256kb cartridge bit 4,5,6 and 7 must be : #84,00,04,00 <- sorry to forget this size
For 512kb cartridge, bit 4,5,6 and 7 must be : #04,01,08,00
Maybe It can help someone, who knows?
