Disabling AR freeze button

Is it possible to disable the Action
Replay freeze function 100% ?

In that case, please enlighten me... :)

There is no huge operation involved, and every sub-operation has an upper bound for data to be accessed and logical complexity.

Anyhow, this discussion doesn't really belong here, plus bigger/faster FPGAs and other devices will come along eventually, allowing for straight-forward raw image operation.

I still think you can master a tape that will always load but never on emulator. I should maybe give that a try :)

But will you be able to duplicate during manufacturing process? I remember that company duplicating Rubicon tapes had such problems.

Very interesting challenge indeed :)

I'm sure there have been a number of things that have tripped up folk over the years, exile by audigenic comes to mind and more. I guess being subtle about it, instead of "FU you ain't getting it to work" , is a better approach / catches out more folk.

thats a totally different thing :) but indeed, subtle ingame protections are the only ones that *really* work. (spyro on ps1 comes to mind... what a fucking bitch)

Please note that I am not an expert on tape mastering hardware but I wonder did anyone ever did a tape protection scheme that would load on original C64 with stock Datasette but would fail on duplicate done with hardware like Datel Clonemaster?

I've seen this topic but I am not sure it was copy protection issue - I mean it could be one of the possible reasons. I never took a peek into how those devices operate but they must be very simple looking at the PCB.

with high quality tape decks there is very little you can do about dubbing. the usual problems with dual tape copies were almost all related to phase-inverting and some silly auto-gain stuff. both problems do not exist when using two datasettes (but then, you dont have high quality tape decks..)
