i was testing a 2600 jr that i'm planning on putting on ebay, and as i was going through carts to check on it, i decided to see if the burgertime cart that i have with a bad eprom (i can feel the weight difference, and the graphics and sound are messed up) was still alive or not. it was, and for curiousity's sake, i tried it on a pirate 2600 jr i have with 32 games built in. (one that CPUWIZ is intimately familiar with. ) i guess i shouldn't have been surprised to see a difference in the performance between the legit and pirate hardware, but i thought the difference was interesting. first, the legit jr:
one note continually beeps over and over, peter pepper can't leave the top level, the hot dog is misshaped and the buns continually fall down.
and on the pirate:
nothing happen no matter what you do, just the silent screen.
for the heck of it, i tried the spider fighter-labeled cart i have that is actually seaquest inside. (the label is lifted at the end, but there is no sign that the cart has been opened.) it would not boot at all on the legit jr, but came up immediately w/o problem on the pirate.
nothing earth-shattering, but just some little weirdness that i thought i'd share.
