Filename
A filename is specified as a C-language string. This string
has to follow some rules :
0
1
2
x x x x x x x x .
l
length string = 12
l
x = character of the base name (= 8 characters)
'a'
'b'
'k'
'l'
'u'
'v'
'4'
'5'
l
y = kind of file (= 1 character)
's'
standard file
predefined file stored in read-only memory
'c'
custom file
file created by the user and stored in non-volatile read-
write memory
l
z = file index (= 2 characters)
'0'
'1'
- zz specifies the location in memory where the file
is stored
- for standard files : zz = 00..maximum standard files
- for custom files : zz = 00..63 where 00 is reserved
for the file 'none .c00' (file loaded when no signal
is applied).
l
yzz is a unique combination. In other words, no two
files can exist with the same extension yzz.
To specify more than one file you can use the question
mark (?) wildcard character for x, y and z. This wildcard
character can represent any possible character on that
location.
Examples : "ntsc .c01", "svga_60v.s?7", "????????.???"
