GCR decoding on the fly

Wed 1-May-2019 01:47
Hi Linus and everybody,

thanks to this work, i've been inspired to come up with the next step.
Full on-the-fly GCR block read+decode+checksumming on a stock 1541: https://csdb.dk/release/?id=167152

I'd like to write a follow-up guest article about it at some point. :)



Awesome work here I agree, and I just had a chance to look @ something you recently did some work on (Space Beer), and Fuck Me that is a fast loader. I re-ran the demo 3 times to make sure I wasn't just high or something. Which loader is that?

Right, apparently I have two problems: firstly, when I try to register a new account here, I get a database error.

Anyway, the real reason I wanted to post is this: I'm still trying to add autorestore to Spatterlight, and after the fix to Fizmo throw/catch, Fizmo now runs Tethered, but whenever I restore it, auto or manual, I get this:

Game state restored successfully.
(Technical trouble: Invalid error code! Attempting to recover with UNDO.)
Undoing the last turn.
(Technical trouble: Invalid error code!)

This microcomputer is so famous that it's emulated on MAME ( emulator that is mostly known for arcade emulation)

This is absolutely the most impressive thing I've seen done with this type of micro controller. You have my respect good Sir!

It says 'Please come back later'.
And the Austrian text version is missing an E, or rather: the E should shift:

I think there may be a bug with (fungibility enabled appearance $ $ $)

I noticed that when I had (fungibility enabled) an explicit (appearance $ $ $) rule set on an object did not fire until the object had been moved. After a bit of digging I came to the conclusion that the problem was with stdlib line 3788. What seems to be happening is that when nothing's been touched the list being handled by (fungibility-enabled appearance $ $ $) starts with an object with no appearance, which means that a rule fails on the first object and it never recurses.

If I add an (or) so that it reads

(if)($Ninc = 1)(then)
(appearance $Head $Rel $Loc)

it works. I'm not sure that adding an (or) simply to prevent failure is good style of course ...

I think there may be a bug with (fungibility enabled appearance $ $ $)

Thank you! This was indeed a bug, and I've added the '(or)' in library version 0.24. I think it's a reasonably clean fix. The alternative would have been to add a default rule definition for '(appearance $ $ $)' with a blank rule body, but such a change would also have affected stories that do not make use of fungibility, so I decided against it. For now, at least.
