Flashcard work on the same idea, same design
Hardware is: A chip + A memory Chip
Software: Simple Kernel, with a menu can run game, with a file for fix game list
But what a simple kernel cant run with every flashcard,
is because of the "Addresses" of the hardware !
You dont have the right addresses, you cant run your kernel on it!
Wood, for example, can run on every flashcard, if "YWG" add all the hardware addresses
of each flashcard in his wood !
You can see with YSMenu, you have YSMenu for R4/M3 Simply,
YSMenu for M3 REAL/M3i Zero, YSMenu for DSTT, etc...
So, to run WOOD, we need to decrypt, edit the program,
find the Hardware addresses, change them, and it will work!
