Yeah, I had kind of excluded the MAX basic from the list for exactly 
that reason. As you know, the cartridge port on the Max is subtely 
different and you don't have the same select lines exposed so it seemed 
easiest to use the /exram line to gate the latch. Maybe you have an idea 
for how we can use alternative lines that exposed that will leave the 
/exram free for it's intended purpose?

The list of images I was going with was:

;    1    Avenger V02
;    2    Avenger V03 - C64
;   3    Billiards V02
;    4    Bowling
;    5    Clowns V02
;    6    Gorf
;    7    Jupiter Lander V02
;    8    Kickman V03
;    9    Le Mans
;    10    Mole Attack
;    11    Money Wars
;    12    Music Composer
;    13    Music Machine
;    14    Omega Race V02
;    15    Omega Race V03
;    16    Radar Rat Race V02B
;    17    Road Race V02
;    18    Seawolf
;    19    Speed Bingo / Math
;    20    Super Alien
;    21    Visible Solar System
;    22    Wizard of Wor V02
;    23    Mini Basic

The only 3 other Max compatible cartridges I was aware of that are not 
on the list are Max Basic, Pinball & Slalom where the last 2 have ROM's 
in the /ROML bank.

Cheers,

Rob
