Installation:

    Unpack the original "makaveli.exe" with xfddecrunch or similar
tool (it's Crunchmania packed) Then apply makaveli.pch with the
supplied spatch utility.

    Run the demo from cold boot with all the caches on. Note that the
module player routine in the demo doesn't like VBR in fast mem and
other screen modes than PAL aren't handled correctly.

CPU CACHE
makaveli.exe

Note! Do not apply this patch if you own M68030

Description:

    The original version of the demo doesn't work on M68040 or M68060
because it uses self modifying code heavily and depends on certain
bits of the CACR register to clear the caches which simply aren't
there on these processors. It would be a better idea to use
exec.library functions CacheClearE() and CacheClearU() to perform this
task. Then you can be rest assured that it will work on all the
processors.

    For you technically minded here are the M68040 CACR register bits:

31 - DE (Enable data cache)
15 - IE (Enable instruction cache)

Other bits are undefined and should be kept zero.

    M68060 CACR register bits:

31 - EDC (Enable data cache)
30 - NAD (No allocate mode)
29 - ESB (Enable store buffer)
28 - DPI (Disable CPUSH invalidation)
27 - FOC (1/2 Cache mode operation)
23 - EBC (Enable branch cache)
22 - CABC (Clear all entries in the branch cache)
21 - CUBC (Clear all user entries in the branch cache)
15 - EIC (Enable instruction cache)
14 - NAI (No allocate mode)
13 - FIC (1/2 Cache mode operation)

Other bits are reserved by Motorola and should be kept zero.
