XCONTROL patches
================
This archive contains programs and data related to updating XCONTROL modules
for CT60 copyback-cache support.  It currently updates the following modules:
    XCONTROL.ACC v1.31 (French, UK, and USA versions)
    GENERAL.CPX v1.30 (French) & v1.40 (English)

The updated XCONTROL is backward-compatible, and may be used on a standard
Atari system as well as a CT60-accelerated Falcon.  However, the updated
GENERAL is intended for the CT60 only and, unlike the original version,
does not support cache control on 68030 systems.  For this reason, it may
be desirable to rename it (to e.g. GENERAL6.CPX) so that both the old and
new versions may be concurrently active in the CPX folder.
