Subject: dragon: Fix stack offsets in usermem get/put functions
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=bd05f3aafb97463da0c99b73a89609b8c8ae0ba3;p=FUZIX.git

dragon: Fix stack offsets in usermem get/put functions

In commit 9b442847 the CC register was added to the stack, but the
new offsets to the passed values were not correctly modified.
The CC register takes only one byte on the stack.
