TAPClean: Enigma Variations scanner improved

The load/end address gathering of all files in a non-multiload game is now available for the “Enigma” scanner in TAPClean.

With this new piece of functionality all data blocks in a non-multiload game (most games using this loader are single-load) can be verified for integrity. What this means in practice:

  • the broken last pulse of the last data byte can now be detected and repaired (manually as it requires content inspection and information reconstruction);
  • pulses that belong to the trailer are not being mixed with the data itself any longer (there are a few cases in which there is a trailer sequence even if most Enigma files haven’t got it): this is expected to produce an overall CRC-32 that does not match what we have documented previously. Hopefully this is only the case for a few tapes;
  • every raw dump of game using the Enigma loader should be checked with TAPClean 0.32-pre2 (in CVS) and cleaned: in case of non 100% recognition I am more than happy to assess the situation;

I am happy to manually test those titles that are not supported in TAPClean due to the fact they use multiload to load subsequent stages (e.g. “Rally Cross” and “Implosion”), if you care sending through your raw dumps.

Dig your dumps and do your bit now 🙂
