 In 0.125u9 it's worse, you don't even have to enable the relative address cheat - even trying to run lastblad now causes MAME to crash straightaway with this error:-

D:\Emulators\Arcade\MAME>mame lastblad
cheat: [cheat entry] memory allocation error
length = 00000015
new_length = 00000016
cheat_list = 00000000

 (In 0.126) Either this:

c:\mame>mame avsp
cheat: [cheat action] memory allocation error
        length = 00000006
        new_length = 00000007
        action_list = 00000000

or an exception like that:

c:\mame>mame avsp

 Redesign of the cheat system is in progress.
Bugs for the old system are invalid now.
