Trilogic Expert Disassembly
I wonder if anyone here ever did a complete disassembly of any of Trilogic Expert monitors programs and is willing to share it?
The rationale behind it: I prefer Expert drivers 2.x without the multimenu but they lack illegal opcode support and any driver I am aware of does not support direct access to drive memory and disk sectors. I'd like to try to add at least some of the missing functionality. Superfluid release inspired me ;)
On the other hand those early Expert drivers have some usefull functions like # (get file size) or B (list basic bypassing some simple antilisting tricks) for example.
I've started to take a peek at 2.9 (the one in the most popular crt file) but due to time constrains it may take some time. |

Not really unfortunately :(- had time to load it into IDA and make few comments. In the meantime however it turned out that Expert emulation is somehow broken in Vice. Here is the discussion: http://www.lemon64.com/forum/viewtopic.php?t=65416
and here is the bug report:
https://sourceforge.net/p/vice-emu/bugs/939/
I had never used "Z" command since I've been always doing crunching manually without Expert so for all those years I never noticed that bug.
Coming back to original topic: if someone has those sources or is willing to help/cooperate I'm open for proposals ;) |

if you want to help fixing this in VICE... having test programs that check the memory map on various different register settings (and in normal and in freezer mode) would speed up the process a lot. i have an expert cartridge here to cross-check against, but i dont have time to spend on making test programs right now. (you can look at https://sourceforge.net/p/vice-emu/code/HEAD/tree/testprogs/C64.. for inspiration :)) |
