100% versions..? Party versions..? etc..?

So, I was wondering ...

Both "Delirious 11" and "X Marks the Spot" have the RESTORE key crash... and "X Marks" has a last minute glitch that crept in...

For myself I'd love to release a 100% version ... but I also kinda wouldn't - because doing so "dirties" the CSDB releases somewhat ... there'd then be something like an "X Marks Party Version" and "X Marks 100% Version" sullying the charts ........

I know Comaland had a 100% version, I can see it right now sat nicely at #2 in the charts ... but that version has more changed since the party version than what I'd likely do...

What do others think? Leave the demos alone and move on .. or go back and fix them.

What I said at X was ”don’t tell Burglar not to press Restore, as that might trigger him to actually press it” ;)

The only disadvantage of Krills proposal that I see is that you cannot use $dd04 and $dd05 any more to put a jump directly into the CIA timer A, so you can only jump indirectly with jmp ($dd04).
And no, I don't want to store code into data direction registers of the CIAs.
2 cycles wasted ...

The Burglar cannot push restore if you disable his hand!

Alright, then how about this:

Have the 63-cycle period in a CIA2 timer (A or B does not matter) and let it trigger interrupts (NMIs).
Then have the 9-cycle counter in CIA1 timer B. CIA1 timer A counter registers $dc04/05 are free to use for the JMP opcode $4c and the jump address lo-byte. The jump address hi-byte is $dc06 (the current cycle counter of timer B), so you can point the NMI vector to $dc04.

That is, the second timer does not need to count underflows of the other timer. Both merely need to be synchronised, which is only a matter of starting them at the correct time, as both are running with the same clock.

@Krill : still the problem is not solved of writing values to $d011 at the wrong time (without extras checks this will happen), which results in shifting bad lines all over your screen layout. Also a problem is running into unintended VSP problems.
