AR 7.0 freeze bug (?)
Hi there!
At the weekend I was coding on my c128, when this bug costed me about half an hour extra... I thought that my code locks up, but it was the AR's failure IMHO.
it's the following:
inc $d020:jmp *-3
when I place the above code at $9000, start it, and push the freeze button,the machine either locks, or the freezer shows that the code was stopped at $e4xx or some other egzotic mem location.
the same code can be freezed nicely if run at $2000.
What can be the explanation to this ? My AR is buggy ? or this is a feature, not a bug ? |

Oswald, you have too rude fingers! Freezing needs loose wrist with gentle passion. :)
I will try it for you, if it's the case with my mk7.
BEst regards,
Clarence
ps: when will you reply my priv. message?? |

Clarence, old pal :)
yes, ofcourse I know it does matter HOW I press the freeze button, but this bug (?) is not due my rude fingers I'm sure. |

the problem is the bouncing of the button which can cause another freeze in the early stages of the freeze routines. this bug has been fixed in the retro replay hardware. |

argh..
as I wrote:
I can freeze running code at $2000 anytime
but when I freeze code running at $9000 it locks the machine anytime.
its not the FUCKING button. |

Oswald,
under vice and ccs it works, as soon as I get home I will test it for you. Maybe it's a c128 thingy?! |

Clarence: the hardware is too much the same, but might be...
the strangest thing in this, that I use the cart since about 8 years by now with the c128, and I've never experienced anything similar... and I have a strange feeling, that when I will check it today at home, this bug wont show up again.. lets see.. :) |

Oswald,
it's the same here with my c64. Weird...
It goes to address e9xx or eaxx when freezing, but on 2000 it's fine.

wow! now thats strange :) So graham whats up with the buttons ? :)
Maybe its caused by the AR rom, since its somewhere around 8000-a000 if I'm not wrong.. could it be that when freezing the rom gets turned on, but the code at 9000 is not yet "freezed" ? |

Sounds very interesting ... will dig into the AR code for that and update you on the weekend or so :)
Everybody: write exactly what version you are using! V7 is something non-standard according to my researches. Real development only happened up to version 5. On v6 a little bug was fixed and a the white screen introduced plus some cosmetic changes.
Other versions, such as 7.0, 8.0 or translations have no reliable versioning anymore at all eventhough they are regionally far spread. (e.g. some german "Action Cartridge 7" was sold on teleshop. It IS an action replay, but strangely translated and renamed. Similar happened to some clone-carts in eastern europe regions.)
Also, for testing wether it is a hardware or software problem, one may try using a nordic power cartridge whenever available. The hardware was cloned, aswell as the software, but some little things have changed which may fix such a bug.
Several monitor bugs are the same on both carts.
More info at rr.c64.org in the all_in_one package afair. :)
