@ -4,18 +4,4 @@ Unifile/Duofile drivers have surfaced; this is the beginning of their disassembl
|
|||
|
||||
The code for the driver (`df1.driver_code_0x2000`) was extracted from a working disk using Rob Justice's a3driverutil
|
||||
project: https://github.com/robjustice/a3driverutil .
|
||||
The disassembly can be reproduced with the `da65` tool, part of the `cc65` toolchain: https://github.com/cc65/cc65 .
|
||||
The invocation looks like this:
|
||||
|
||||
```
|
||||
da65 df1.driver_code_0x2000 -i unifile.info
|
||||
```
|
||||
|
||||
There are several problems with the disassembly, most notably it isn't capable of making sense of the table of
|
||||
addresses that are "minus-one" values of locations; it's used by the dispatcher to push program counter values
|
||||
to the stack, then running an `RTS` instruction to branch to it. `da65` isn't having it, so right now
|
||||
these values are hacked to be `something-1` so we can at least get a view into what's going on. That will need
|
||||
to be (manually?) fixed up later.
|
||||
|
||||
Also, the constants for SOS return codes as well as zero page addresses can be ambiguous, so a bunch of those aren't
|
||||
being assigned yet.
|
||||
The disassembly and reassembly can be reproduced with Andy McFadden's `6502Bench` tool: https://6502bench.com/ .
