Some games don't like RAM past 16MB. I use a program on my 486 (64MB FPM) and my Toshiba Satellite Pro 410CDT (40MB EDO) that drops the RAM down to 32MB or even 16MB for certain games and it does a great job with it, but, on my 486, I use QEMM 8.03 so my conventional RAM is always at 610KB free.
And the memory management being a big factor with the games is the number 1 thing to look at.
My 410CDT had the CMOS and wake batteries leak, but it didn't cause any damage and it cleaned off rather nicely and my CMOS battery is the Lithium-Vanadium from a parted 4800CT. The main Li-Ion works, but if the laptop is left sitting out in storage for a month or so, the battery goes flat (needs a calibration, but it charges and it runs without the charger being plugged in), much like my PSP 2001 console.
