I purchased a Rescue 911 recently and when I go into settings it shows 150,??0,000 for the 1st replay level. I set it to factory defaults and it shows the same thing. I'm trying to find out if its a RAM or ROM issue. The RAM passes its test but I don't think that is always accurate. Does anyone have the checksum for the 740/2 ROM for Rescue 911? It will display when you turn the game on. I would like to verify mine is correct.

Thank you.

Morning bump. I checked that mine is B401. Any other Rescue owners with 740/2 ROM chips that can check their checksum?

Thanks.

Do you ever run Visual Pinball? It would be perfect for checking something like this. If my R911 wasn't in storage right now, I would have responded with results for you.

PinMAME only has the v1 ROMs available. But it would be interesting for OP to dump his ROM and then try playing it in PinMAME to see if his problem is the ROM.

I don't have visual pinball but Pinball Resource just confirmed by checksum should be B401. But they aren't sure if its a RAM or ROM problem. I'm going to order a new RAM chip since its much cheaper and see what happens.
