Description

Kernel driver for the SuperSmartCard (SSC) Gameboy flash card writer.
The SSC was made by SSL, but I have head that they went out of buisness around '95.

Installation / configuration

To install the driver, just run the install.sh file in the archive.

The driver presumes that you have hooked the write to a parallel port that uses io port 0x378, if this is not the case, you must edit/create the file /boot/home/config/settings/kernel/drivers/ssc and set the ioport option to the right port (on intel you can use the Preferences/Devices app to find the right port).
The scc file should look something like this:

ioport 0x378

If you switch between diffrent devices on you parallel port, you have to use the rescan program to let the ssc driver know that you have changed hardware, you run it from a Terminal, like this:

rescan ssc

Usage

The driver exports these devices in the /dev/misc/ssc directory:

Device	Description
flash/all	all banks (boot+0+1+2+3) for a complete 512Kbytes card
flash/boot	The 64Kbytes boot area, used internaly for the small boot menu.
flash/0	a 64Kbytes bank.
flash/1	a 128Kbytes bank.
flash/2	another 128Kbytes bank.
flash/3	and yet a 128Kbytes bank.
flash/23	bank 2 and 3 joined to a 256Kbytes bank.
ram/0	8Kbytes savegame bank for flash/0
ram/1	8Kbytes savegame bank for flash/1
ram/2	8Kbytes savegame bank for flash/2 or flash/23
ram/3	8Kbytes savegame bank for flash/3

So if you want to install MegaMan X's T2 demo (512K), you just copy it like this:

cp t2.gb /dev/misc/ssc/flash/all

You can also install more that one romimage at a time, this is how you install Anders Granlund's Big Scroll demo, Ian Jame's Bond, Harry Mulder's Kirby XXL and Jeff Frohwein's Basic into one cardridge:

cp Bc.gb /dev/misc/ssc/flash/0
cp bond.gb /dev/misc/ssc/flash/1
cp kirbyxxl.gb /dev/misc/ssc/flash/2
cp basic.gb /dev/misc/ssc/flash/3

The kerneldriver will append a small boot selector to the card, so that you may choose which program to run when you power up the gameboy.

To backup or restore the savegame ram (does not work with the black/transparent color gameboy card's):

cp /dev/misc/ssc/ram/0 savegame.backup
or
cp savegame.backup /dev/misc/ssc/ram/0

Bugs / limitations

The boot selecter does not work with color programs, so if you want to see color demos, you have to upload them to either the boot or the all bank.

The memory controller in the flash card that comes with the SSC seems to have problems with dma's when the cpu is runnning in dobbelt speed, this means that a lot of demos just won't work :(
