A320 Airbus II Crack Intro issue

[thor]

Thanks for the fixes!

Found another culprit: A320 Airbus II Crack Intro (19xx)(TRSI).adf (61170F72).
Tested with the three Kick1.3 1MB total quickstart settings:

1.3.2: everything fine
1.3.3: text output extremly slow
1.3.4 beta 1: no text output, no music
1.3.4 beta 2: no text output, with music

It does work in all those versions, if cycle-exact is disabled

Haha. Guess what, cycle-exact mode is correct... Confirmed on my real A500, works 100% identically (=text writer freezes after 2 characters)

Added:

I debugged this (because I thought it was a bug in UAE..) and it freezes because of CIA TOD "bug" (explained here) Demo enables both EXTER and VERTB interrupts (EXTER probably accidentally), TOD counts to 0x1000 -> "buggy" ALARM interrupt -> EXTER interrupt -> KS 1.3 EXTER handler gets confused and enables BLIT interrupt -> intro's VERTB handler gets BLIT interrupt but it never clears it -> freeze..

What does this mean? Either this intro was never tested on KS 1.3/1.2 Amigas or there are some non-buggy CIAs. (highly unlikely but you never know)

Moved from WinUAE beta #2 thread.

I think this intro needs more real Amiga testing.. This is quite interesting case

If it means anything A320 Airbus II came out long after the A1200 was launched.

Even though the game is only OCS/ECS, what are the chances this cracktro was coded on an A1200?

Would be still strange as A320 Airbus II works on A500s too and the cracktro breaks that even when there wasn't something to crack.
