7 Programming the ﬂash ROM

restriction to 64k blocks does of course not apply to the freezer RAM. There every 8k

bank can be programmed separately.

If the start bank is not at a 64k block boundary, then the ﬂash program asks if the

complete 64k block shall ﬁrst be erased or not. If the 64k block is not erased, unused (

e. g.

previously erased) parts of a 64k block can be ﬁlled with data. If you accidentally try to

overwrite already used parts, an error message appears and you have to re-program the

complete 64k block.

7.3 Starting the ﬂash program

To program the ﬂash ROM resp. the freezer RAM the “

FlashWrite

” switch must be

turned right (

). The program

FLASH.COM

must be loaded from the system disk. If the

switch is turned

OFF

, then the program will not ﬁnd the ﬂash ROM and will output an

error message. In this case you can turn the switch right and conﬁrm the question

restart

program?

with

[Y]

. The ﬂash program outputs the following information when it starts:

• Type of the ﬂash ROM

• Version number and date of freezer software in the ﬂash ROM

In case no freezer software is present in the ﬂash ROM, the output reads

n/a

instead of

the version number. The version number can also be displayed in the debugger via the

VER command.

7.4 Using the ﬂash program

The ﬂash program oﬀers the following operations:

Program CartEmu flash

Program the ﬂash ROM area of the cartridge emulation (banks 0. . . 119). The

area for the freezer software (banks 120. . . 127) remains protected in this case

and cannot be overwritten accidentally. If you only work with the cartridge

emulation, then you should always only use this operation.

Program CartEmu+Freezer flash

Program the complete ﬂash ROM (banks 0. . . 127). With this you can update

also the freezer software (banks 120. . . 127).

Write flash to file

Write the ﬂash ROM content to a ﬁle.

Program RAM

Program the freezer RAM (banks 0. . . 47).

Write RAM to file

Write the freezer RAM content to a ﬁle.
