Strange cartridge issue [V1.38]
ULTIMATE 64: Firmware V1.38 ... Some games with cartridge protection detect cartridges and fails on running games properly - even when no internal/external cartridge is enabled. Example: My legal tape original of Great Gurianos by Elite Software runs the program after loading the last block. However, the game cannot be played. A message "REMOVE CARTRIDGE AND RELOAD" scrolls across locking the game from being played.
That is quite interesting indeed. I'd love to see the code that performs this test, so I can figure out what it sees.

does it do this in VICE as well? if so, the TAP file would be useful in diagnosing the issue
It works in VICE with Action Replay plugged in and unplugged if "fast load option (F7)" is not used. Otherwise like with the Ultimate 64, the game is locked.
Yeah, seems to be all the same problem indeed. :-) The solution is already known, but just needs to be implemented and tested. BTW, @p2mate , since you have provided patches to some titles, maybe you could help to extract some failing code from another demo, in such a way that a PRG file is created that exposes the problem right from the start?
Barry McGuigan World Championship Boxing_MRZ detection code reimplemented as a standalone prg. Only tested on vice and 1.37 U64 so far. I don't actually own a real C64 anymore.
Update: Also works on fw 1.28
@p2mate The demo is vampy. I am on it already. And it is not related to this issue.
