i remember something on jrok or clay's site about increasing the value of an electrolytic cap to fix this problem.

i'll see if i can find it for you.
-------------------------------------
found it, jroks site says:

As part of this project I also discovered another problem which was occurring to three other Q*Bert boards. Even though the high-scores were being saved, they would get reset or corrupted without warning ! This turned out to be a reset error, the capacitor which gives a delay on the CPU reset was failing, causing the CPU reset to be too short a time period. This was fixed by replacement of capacitor C25 with a 470uF electrolytic.
-----------------------------------------

so there's something to try.
