He, he, he, this is the original Karnov...
Use cheats then:
... Pugsy's MAME cheats
has just been updated to v0.106
(about time, the last one was for MAME v0.81 - 21 April 2004) http://cheat.retrogames.com/
... Extract this to the root of your MAME32 directory.
... Once the game has loaded, press <TAB> and then go down to the Cheats menu.
... Select your desired cheats.
PS. I hope that you are using MAME32 (Windows GUI) and not MAME (command line based). You can get the latest version of MAME32 from http://mame32qa.classicgaming.gamespy.com/
Although try to find v0.106 and not v0.106u1 (as MAME Devs are playing around with re-writing the video systems, bound to be issues)...
If you cannot find MAME32 v0.106 then let me know and I'll upload it to YouSendIt for you...
