.CRT File Format – Hardware types

The list, and where it ends

The two bytes at $16 of the header name the cartridge's hardware, and with it how its banks are switched. This list has 80 types, 0 to 79. It is the table of VICE 3.8's cartconv program: its names were read from the strings of the program on this machine (it could not be run), and each number is the name's position in that table, which comes in this order and agrees with the numbering of the format description as remembered. No number was read from a file. Newer VICE versions have further types after 79 (they are not listed because no source for them was available), so a larger number is not an error of the file, only of this list. The names are as the tool prints them, with some spelled out.

Only the types marked described have a line on how their banks are switched; that line says what the hardware does and was not checked against hardware. For the others the explorer names the type and shows every chip at its own load address. The same numbers are used by the C64 only: the C128, VIC-20 and Plus/4 images have their own, shorter lists, which this page does not have.

Not described

Known, not yet covered

• Reference: the bank-switching rules of the 74 types marked not described. They are documented in the VICE source and manual, which are not on this machine.
• Reference: the types above 79.

Unknown

• Reference: the numbers of the table were taken from the order of the names and not from a file or a document; one name out of place would shift the types after it. The order was checked only against the order of the strings in the converter.
